This listener is triggered when the Sidebar is expanded.
Parameters ▼
fn: Callable | None | Literal['decorator']
default `= "decorator"`
the function to call when this event is triggered. Often a machine learning
model's prediction function. Each parameter of the function corresponds to one
input component, and the function should return a single value or a tuple of
values, with each element in the tuple corresponding to one output component.
inputs: Component | B | expand | https://gradio.app/docs/gradio/sidebar | Gradio - Sidebar Docs |
to one
input component, and the function should return a single value or a tuple of
values, with each element in the tuple corresponding to one output component.
inputs: Component | BlockContext | list[Component | BlockContext] | Set[Component | BlockContext] | None
default `= None`
List of gradio.components to use as inputs. If the function takes no inputs,
this should be an empty list.
outputs: Component | BlockContext | list[Component | BlockContext] | Set[Component | BlockContext] | None
default `= None`
List of gradio.components to use as outputs. If the function returns no
outputs, this should be an empty list.
api_name: str | None
default `= None`
defines how the endpoint appears in the API docs. Can be a string or None. If
set to a string, the endpoint will be exposed in the API docs with the given
name. If None (default), the name of the function will be used as the API
endpoint.
api_description: str | None | Literal[False]
default `= None`
Description of the API endpoint. Can be a string, None, or False. If set to a
string, the endpoint will be exposed in the API docs with the given
description. If None, the function's docstring will be used as the API
endpoint description. If False, then no description will be displayed in the
API docs.
scroll_to_output: bool
default `= False`
If True, will scroll to output component on completion
show_progress: Literal['full', 'minimal', 'hidden']
default `= "full"`
how to show the progress animation while event is running: "full" shows a
spinner which covers the output component area as well as a runtime display in
the upper right corner, "minimal" only shows the runtime display, "hidden"
shows no progress animation at all
show_progress_on: Component | list[Component] | None
default `= None`
Component or list of components to show the progress animation on. If None,
will show the progress animat | expand | https://gradio.app/docs/gradio/sidebar | Gradio - Sidebar Docs |
at all
show_progress_on: Component | list[Component] | None
default `= None`
Component or list of components to show the progress animation on. If None,
will show the progress animation on all of the output components.
queue: bool
default `= True`
If True, will place the request on the queue, if the queue has been enabled.
If False, will not put this event on the queue, even if the queue has been
enabled. If None, will use the queue setting of the gradio app.
batch: bool
default `= False`
If True, then the function should process a batch of inputs, meaning that it
should accept a list of input values for each parameter. The lists should be
of equal length (and be up to length `max_batch_size`). The function is then
*required* to return a tuple of lists (even if there is only 1 output
component), with each list in the tuple corresponding to one output component.
max_batch_size: int
default `= 4`
Maximum number of inputs to batch together if this is called from the queue
(only relevant if batch=True)
preprocess: bool
default `= True`
If False, will not run preprocessing of component data before running 'fn'
(e.g. leaving it as a base64 string if this method is called with the `Image`
component).
postprocess: bool
default `= True`
If False, will not run postprocessing of component data before returning 'fn'
output to the browser.
cancels: dict[str, Any] | list[dict[str, Any]] | None
default `= None`
A list of other events to cancel when this listener is triggered. For example,
setting cancels=[click_event] will cancel the click_event, where click_event
is the return value of another components .click method. Functions that have
not yet run (or generators that are iterating) will be cancelled, but
functions that are currently running will be allowed to finish.
trigger_mode: Literal['once', 'multiple', 'always_last'] | None
defaul | expand | https://gradio.app/docs/gradio/sidebar | Gradio - Sidebar Docs |
ators that are iterating) will be cancelled, but
functions that are currently running will be allowed to finish.
trigger_mode: Literal['once', 'multiple', 'always_last'] | None
default `= None`
If "once" (default for all events except `.change()`) would not allow any
submissions while an event is pending. If set to "multiple", unlimited
submissions are allowed while pending, and "always_last" (default for
`.change()` and `.key_up()` events) would allow a second submission after the
pending event is complete.
js: str | Literal[True] | None
default `= None`
Optional frontend js method to run before running 'fn'. Input arguments for js
method are values of 'inputs' and 'outputs', return should be a list of values
for output components.
concurrency_limit: int | None | Literal['default']
default `= "default"`
If set, this is the maximum number of this event that can be running
simultaneously. Can be set to None to mean no concurrency_limit (any number of
this event can be running simultaneously). Set to "default" to use the default
concurrency limit (defined by the `default_concurrency_limit` parameter in
`Blocks.queue()`, which itself is 1 by default).
concurrency_id: str | None
default `= None`
If set, this is the id of the concurrency group. Events with the same
concurrency_id will be limited by the lowest set concurrency_limit.
api_visibility: Literal['public', 'private', 'undocumented']
default `= "public"`
controls the visibility and accessibility of this endpoint. Can be "public"
(shown in API docs and callable by clients), "private" (hidden from API docs
and not callable by clients), or "undocumented" (hidden from API docs but
callable by clients and via gr.load). If fn is None, api_visibility will
automatically be set to "private".
time_limit: int | None
default `= None`
stream_every: float
default `= 0.5`
key: int | str | t | expand | https://gradio.app/docs/gradio/sidebar | Gradio - Sidebar Docs |
api_visibility will
automatically be set to "private".
time_limit: int | None
default `= None`
stream_every: float
default `= 0.5`
key: int | str | tuple[int | str, ...] | None
default `= None`
A unique key for this event listener to be used in @gr.render(). If set, this
value identifies an event as identical across re-renders when the key is
identical.
validator: Callable | None
default `= None`
Optional validation function to run before the main function. If provided,
this function will be executed first with queue=False, and only if it
completes successfully will the main function be called. The validator
receives the same inputs as the main function and should return a
`gr.validate()` for each input value.

Creates a button, that when clicked, allows a user to download a single
file of arbitrary type.
| Description | https://gradio.app/docs/gradio/downloadbutton | Gradio - Downloadbutton Docs |
**Using DownloadButton as an input component.**
How DownloadButton will pass its value to your function:
Type: `str | None`
(Rarely used) passes the file as a `str` into the function.
Example Code
import gradio as gr
def predict(
value: str | None
):
process value from the DownloadButton component
return "prediction"
interface = gr.Interface(predict, gr.DownloadButton(), gr.Textbox())
interface.launch()
**Using DownloadButton as an output component**
How DownloadButton expects you to return a value:
Type: `str | Path | None`
Expects a `str` or `pathlib.Path` filepath
Example Code
import gradio as gr
def predict(text) -> str | Path | None
process value to return to the DownloadButton component
return value
interface = gr.Interface(predict, gr.Textbox(), gr.DownloadButton())
interface.launch()
| Behavior | https://gradio.app/docs/gradio/downloadbutton | Gradio - Downloadbutton Docs |
Parameters ▼
label: str
default `= "Download"`
Text to display on the button. Defaults to "Download".
value: str | Path | Callable | None
default `= None`
A str or pathlib.Path filepath or URL to download, or a Callable that returns
a str or pathlib.Path filepath or URL to download.
every: Timer | float | None
default `= None`
Continously calls `value` to recalculate it if `value` is a function (has no
effect otherwise). Can provide a Timer whose tick resets `value`, or a float
that provides the regular interval for the reset Timer.
inputs: Component | list[Component] | set[Component] | None
default `= None`
Components that are used as inputs to calculate `value` if `value` is a
function (has no effect otherwise). `value` is recalculated any time the
inputs change.
variant: Literal['primary', 'secondary', 'stop']
default `= "secondary"`
'primary' for main call-to-action, 'secondary' for a more subdued style,
'stop' for a stop button.
visible: bool | Literal['hidden']
default `= True`
If False, component will be hidden. If "hidden", component will be visually
hidden and not take up space in the layout but still exist in the DOM

default `= "lg"`
size of the button. Can be "sm", "md", or "lg".
icon: str | None
default `= None`
URL or path to the icon file to display within the button. If None, no icon
will be displayed.
scale: int | None
default `= None`
relative size compared to adjacent Components. For example if Components A and
B are in a Row, and A has scale=2, and B has scale=1, A will be twice as wide
as B. Should be an integer. scale applies in Rows, and to top-level Components
in Blocks where fill_height=True.
min_width: int | None
default `= None`
minimum pixel width, will wrap if not sufficient screen space to satisfy this
value. If a certain scale v | Initialization | https://gradio.app/docs/gradio/downloadbutton | Gradio - Downloadbutton Docs |
nts
in Blocks where fill_height=True.
min_width: int | None
default `= None`
minimum pixel width, will wrap if not sufficient screen space to satisfy this
value. If a certain scale value results in this Component being narrower than
min_width, the min_width parameter will be respected first.

default `= True`
If False, the UploadButton will be in a disabled state.
elem_id: str | None
default `= None`
An optional string that is assigned as the id of this component in the HTML
DOM. Can be used for targeting CSS styles.

default `= None`
An optional list of strings that are assigned as the classes of this component
in the HTML DOM. Can be used for targeting CSS styles.
render: bool
default `= True`
If False, component will not render be rendered in the Blocks context. Should
be used if the intention is to assign event listeners now but render the
component later.
key: int | str | tuple[int | str, ...] | None
default `= None`
in a gr.render, Components with the same key across re-renders are treated as
the same component, not a new component. Properties set in 'preserved_by_key'
are not reset across a re-render.
preserved_by_key: list[str] | str | None
default `= "value"`
A list of parameters from this component's constructor. Inside a gr.render()
function, if a component is re-rendered with the same key, these (and only
these) parameters will be preserved in the UI (if they have been changed by
the user or an event listener) instead of re-rendered based on the values
provided during constructor.

Description
Event listeners allow you to respond to user interactions with the UI
components you've defined in a Gradio Blocks app. When a user interacts with
an element, such as changing a slider value or uploading an image, a function
is called.
Supported Event Listeners
The DownloadButton component supports the following event listeners. Each
event listener takes the same parameters, which are listed in the Event
Parameters table below.

Blocks is Gradio's low-level API that allows you to create more custom web
applications and demos than Interfaces (yet still entirely in Python).
Compared to the Interface class, Blocks offers more flexibility and control
over: (1) the layout of components (2) the events that trigger the execution
of functions (3) data flows (e.g. inputs can trigger outputs, which can
trigger the next level of outputs). Blocks also offers ways to group together
related demos such as with tabs.
The basic usage of Blocks is as follows: create a Blocks object, then use it
as a context (with the "with" statement), and then define layouts, components,
or events within the Blocks context. Finally, call the launch() method to
launch the demo.
| Description | https://gradio.app/docs/gradio/blocks | Gradio - Blocks Docs |
import gradio as gr
def update(name):
return f"Welcome to Gradio, {name}!"
with gr.Blocks() as demo:
gr.Markdown("Start typing below and then click **Run** to see the output.")
with gr.Row():
inp = gr.Textbox(placeholder="What is your name?")
out = gr.Textbox()
btn = gr.Button("Run")
btn.click(fn=update, inputs=inp, outputs=out)
demo.launch()
| Example Usage | https://gradio.app/docs/gradio/blocks | Gradio - Blocks Docs |
Parameters ▼
analytics_enabled: bool | None
default `= None`
Whether to allow basic telemetry. If None, will use GRADIO_ANALYTICS_ENABLED
environment variable or default to True.
mode: str
default `= "blocks"`
A human-friendly name for the kind of Blocks or Interface being created. Used
internally for analytics.
title: str | I18nData
default `= "Gradio"`
The tab title to display when this is opened in a browser window.
fill_height: bool
default `= False`
Whether to vertically expand top-level child components to the height of the
window. If True, expansion occurs when the scale value of the child components
>= 1.
fill_width: bool
default `= False`
Whether to horizontally expand to fill container fully. If False, centers and
constrains app to a maximum width. Only applies if this is the outermost
`Blocks` in your Gradio app.
delete_cache: tuple[int, int] | None
default `= None`
A tuple corresponding [frequency, age] both expressed in number of seconds.
Every `frequency` seconds, the temporary files created by this Blocks instance
will be deleted if more than `age` seconds have passed since the file was
created. For example, setting this to (86400, 86400) will delete temporary
files every day. The cache will be deleted entirely when the server restarts.
If None, no cache deletion will occur.

updated components from functions. Defaults to 10000.
share_server_address: str | None
default `= None`
Use this to specify a custom FRP server and port for sharing Gradio apps (only
applies if share=True). If not provided, will use the default FRP server at
https://gradio.live. See https://github.com/huggingface/frp for more
information.
share_server_protocol: Literal['http', 'https'] | None
default `= None`
Use this to specify the protocol to use for the share links. Defaults to
"https", unless a custom share_server_address is provided, in which case it
defaults to "http". If you are using a custom share_server_address and want to
use https, you must set this to "https".
share_server_tls_certificate: str | None
default `= None`
The path to a TLS certificate file to use when connecting to a custom share
server. This parameter is not used with the default FRP server at
https://gradio.live. Otherwise, you must provide a valid TLS certificate file
(e.g. a "cert.pem") relative to the current working directory, or the
connection will not use TLS encryption, which is insecure.
auth_dependency: Callable[[fastapi.Request], str | None] | None
default `= None`
A function that takes a FastAPI request and returns a string user ID or None.
If the functio | launch | https://gradio.app/docs/gradio/blocks | Gradio - Blocks Docs |
nsecure.

be used with external authentication systems like OAuth. Cannot be used with
`auth`.
max_file_size: str | int | None
default `= None`
The maximum file size in bytes that can be uploaded. Can be a string of the

Enables traffic monitoring of the app through the /monitoring endpoint. By
default is None, which enables this endpoint. If explicitly True, will also
print the monitoring URL to the console. If False, will disable monitoring
altogether.
strict_cors: bool
default `= True`
If True, prevents external domains from making requests to a Gradio server
running on localhost. If False, allows requests to localhost that originate
from localhost but also, crucially, from "null". This parameter should
normally be True to prevent CSRF attacks but may need to be False when
embedding a *locally-running Gradio app* using web components.

default `= None`
node_port: int | None
default `= None`
ssr_mode: bool | None
default `= None`
If True, the Gradio app will be rendered using server-side rendering mode,
which is typically more performant and provides better SEO, but this requires
Node 20+ to be installed on the system. If False, the app will be rendered
using client-side rendering mode. If None, will use GRADIO_SSR_MODE
environment variable or default to False.
pwa: bool | None
default `= None`
If True, the Gradio app will | launch | https://gradio.app/docs/gradio/blocks | Gradio - Blocks Docs |
rendered
using client-side rendering mode. If None, will use GRADIO_SSR_MODE
environment variable or default to False.
pwa: bool | None
default `= None`
If True, the Gradio app will be set up as an installable PWA (Progressive Web
App). If set to None (default behavior), then the PWA feature will be enabled
if this Gradio app is launched on Spaces, but not otherwise.

default `= None`
If True, the Gradio app will be set up as an MCP server and documented
functions will be added as MCP tools. If None (default behavior), then the
GRADIO_MCP_SERVER environment variable will be used to determine if the MCP
server should be enabled.
i18n: I18n | None
default `= None`
An I18n instance containing custom translations, which are used to translate
strings in our components (e.g. the labels of components or Markdown strings).
This feature can only be used to translate static text in the frontend, not
values in the backend.
theme: Theme | str | None
default `= None`
A Theme object or a string representing a theme. If a string, will look for a
built-in theme with that name (e.g. "soft" or "default"), or will attempt to
load a theme from the Hugging Face Hub (e.g. "gradio/monochrome"). If None,
will use the Default theme.

Parameters ▼
status_update_rate: float | Literal['auto']
default `= "auto"`
If "auto", Queue will send status estimations to all clients whenever a job is
finished. Otherwise Queue will send status at regular intervals set by this
parameter as the number of seconds.
api_open: | queue | https://gradio.app/docs/gradio/blocks | Gradio - Blocks Docs |
will send status estimations to all clients whenever a job is
finished. Otherwise Queue will send status at regular intervals set by this
parameter as the number of seconds.
api_open: bool | None
default `= None`
If True, the REST routes of the backend will be open, allowing requests made
directly to those endpoints to skip the queue.
max_size: int | None
default `= None`
The maximum number of events the queue will store at any given moment. If the
queue is full, new events will not be added and a user will receive a message
saying that the queue is full. If None, the queue size will be unlimited.
default_concurrency_limit: int | None | Literal['not_set']
default `= "not_set"`
The default value of `concurrency_limit` to use for event listeners that don't
specify a value. Can be set by environment variable
GRADIO_DEFAULT_CONCURRENCY_LIMIT. Defaults to 1 if not set otherwise.

This listener is triggered when the Blocks initially loads in the browser.
Parameters ▼
block: Block | None
fn: Callable | None | Literal['decorator']
default `= "decorator"`
the function to call when this event is triggered. Often a machine learning
model's prediction function. Each parameter of the function corresponds to one
input component, and the function should return a single value or a tuple of
values, with each element in the tuple corresponding to o | load | https://gradio.app/docs/gradio/blocks | Gradio - Blocks Docs |
ction function. Each parameter of the function corresponds to one
input component, and the function should return a single value or a tuple of
values, with each element in the tuple corresponding to one output component.
inputs: Component | BlockContext | list[Component | BlockContext] | Set[Component | BlockContext] | None
default `= None`
List of gradio.components to use as inputs. If the function takes no inputs,
this should be an empty list.
outputs: Component | BlockContext | list[Component | BlockContext] | Set[Component | BlockContext] | None
default `= None`
List of gradio.components to use as outputs. If the function returns no
outputs, this should be an empty list.
api_name: str | None
default `= None`
defines how the endpoint appears in the API docs. Can be a string or None. If
set to a string, the endpoint will be exposed in the API docs with the given
name. If None (default), the name of the function will be used as the API
endpoint.
api_description: str | None | Literal[False]
default `= None`
Description of the API endpoint. Can be a string, None, or False. If set to a
string, the endpoint will be exposed in the API docs with the given
description. If None, the function's docstring will be used as the API
endpoint description. If False, then no description will be displayed in the
API docs.
scroll_to_output: bool
default `= False`
If True, will scroll to output component on completion
show_progress: Literal['full', 'minimal', 'hidden']
default `= "full"`
how to show the progress animation while event is running: "full" shows a
spinner which covers the output component area as well as a runtime display in
the upper right corner, "minimal" only shows the runtime display, "hidden"
shows no progress animation at all
show_progress_on: Component | list[Component] | None
default `= None`
Component or list of components to show the pro | load | https://gradio.app/docs/gradio/blocks | Gradio - Blocks Docs |
the runtime display, "hidden"
shows no progress animation at all
show_progress_on: Component | list[Component] | None
default `= None`
Component or list of components to show the progress animation on. If None,
will show the progress animation on all of the output components.
queue: bool
default `= True`
If True, will place the request on the queue, if the queue has been enabled.
If False, will not put this event on the queue, even if the queue has been
enabled. If None, will use the queue setting of the gradio app.
batch: bool
default `= False`
If True, then the function should process a batch of inputs, meaning that it
should accept a list of input values for each parameter. The lists should be
of equal length (and be up to length `max_batch_size`). The function is then
*required* to return a tuple of lists (even if there is only 1 output
component), with each list in the tuple corresponding to one output component.
max_batch_size: int
default `= 4`
Maximum number of inputs to batch together if this is called from the queue
(only relevant if batch=True)
preprocess: bool
default `= True`
If False, will not run preprocessing of component data before running 'fn'
(e.g. leaving it as a base64 string if this method is called with the `Image`
component).
postprocess: bool
default `= True`
If False, will not run postprocessing of component data before returning 'fn'
output to the browser.
cancels: dict[str, Any] | list[dict[str, Any]] | None
default `= None`
A list of other events to cancel when this listener is triggered. For example,
setting cancels=[click_event] will cancel the click_event, where click_event
is the return value of another components .click method. Functions that have
not yet run (or generators that are iterating) will be cancelled, but
functions that are currently running will be allowed to finish.
trigger_mode: | load | https://gradio.app/docs/gradio/blocks | Gradio - Blocks Docs |
s .click method. Functions that have
not yet run (or generators that are iterating) will be cancelled, but
functions that are currently running will be allowed to finish.
trigger_mode: Literal['once', 'multiple', 'always_last'] | None
default `= None`
If "once" (default for all events except `.change()`) would not allow any
submissions while an event is pending. If set to "multiple", unlimited
submissions are allowed while pending, and "always_last" (default for
`.change()` and `.key_up()` events) would allow a second submission after the
pending event is complete.
js: str | Literal[True] | None
default `= None`
Optional frontend js method to run before running 'fn'. Input arguments for js
method are values of 'inputs' and 'outputs', return should be a list of values
for output components.
concurrency_limit: int | None | Literal['default']
default `= "default"`
If set, this is the maximum number of this event that can be running
simultaneously. Can be set to None to mean no concurrency_limit (any number of
this event can be running simultaneously). Set to "default" to use the default
concurrency limit (defined by the `default_concurrency_limit` parameter in
`Blocks.queue()`, which itself is 1 by default).
concurrency_id: str | None
default `= None`
If set, this is the id of the concurrency group. Events with the same
concurrency_id will be limited by the lowest set concurrency_limit.
api_visibility: Literal['public', 'private', 'undocumented']
default `= "public"`
controls the visibility and accessibility of this endpoint. Can be "public"
(shown in API docs and callable by clients), "private" (hidden from API docs
and not callable by clients), or "undocumented" (hidden from API docs but
callable by clients and via gr.load). If fn is None, api_visibility will
automatically be set to "private".
time_limit: int | None
default `= None`
stream_every: | load | https://gradio.app/docs/gradio/blocks | Gradio - Blocks Docs |
s but
callable by clients and via gr.load). If fn is None, api_visibility will
automatically be set to "private".
time_limit: int | None
default `= None`
stream_every: float
default `= 0.5`
key: int | str | tuple[int | str, ...] | None
default `= None`
A unique key for this event listener to be used in @gr.render(). If set, this
value identifies an event as identical across re-renders when the key is
identical.
validator: Callable | None
default `= None`
Optional validation function to run before the main function. If provided,
this function will be executed first with queue=False, and only if it
completes successfully will the main function be called. The validator
receives the same inputs as the main function and should return a
`gr.validate()` for each input value.

Reduce capacity to reduce memory usage when using gradio.State or returning
updated components from functions. Defaults to 10000.
share_server_address: str | None
default `= None`
Use this to specify a custom FRP server and port for sharing Gradio apps (only
applies if share=True). If not provided, will use the default FRP server at
https://gradio.live. See https://github.com/huggingface/frp for more
information.
share_server_protocol: Literal['http', 'https'] | None
default `= None`
Use this to specify the protocol to use for the share links. Defaults to
"https", unless a custom share_server_address is provided, in which case it
defaults to "http". If you are using a custom share_server_address and want to
use https, you must set this to "https".
share_server_tls_certificate: str | None
default `= None`
The path to a TLS certificate file to use when connecting to a custom share
server. This parameter is not used with the default FRP server at
https://gradio.live. Otherwise, you must provide a valid TLS certificate file
(e.g. a "cert.pem") relative to the current working directory, or the
connection will not use TLS encryption, which is insecure.
auth_dependency: Callable[[fastapi.Request], str | None] | None
default `= None`
A function that takes a FastAPI request and returns a string user ID or None.
If the functio | launch | https://gradio.app/docs/gradio/blocks | Gradio - Blocks Docs |
nsecure.
auth_dependency: Callable[[fastapi.Request], str | None] | None
default `= None`
A function that takes a FastAPI request and returns a string user ID or None.
If the function returns None for a specific request, that user is not
authorized to access the app (they will see a 401 Unauthorized response). To
be used with external authentication systems like OAuth. Cannot be used with
`auth`.
max_file_size: str | int | None
default `= None`
The maximum file size in bytes that can be uploaded. Can be a string of the
form "<value><unit>", where value is any positive integer and unit is one of
"b", "kb", "mb", "gb", "tb". If None, no limit is set.
enable_monitoring: bool | None
default `= None`
Enables traffic monitoring of the app through the /monitoring endpoint. By
default is None, which enables this endpoint. If explicitly True, will also
print the monitoring URL to the console. If False, will disable monitoring
altogether.
strict_cors: bool
default `= True`
If True, prevents external domains from making requests to a Gradio server
running on localhost. If False, allows requests to localhost that originate
from localhost but also, crucially, from "null". This parameter should
normally be True to prevent CSRF attacks but may need to be False when
embedding a *locally-running Gradio app* using web components.
node_server_name: str | None
default `= None`
node_port: int | None
default `= None`
ssr_mode: bool | None
default `= None`
If True, the Gradio app will be rendered using server-side rendering mode,
which is typically more performant and provides better SEO, but this requires
Node 20+ to be installed on the system. If False, the app will be rendered
using client-side rendering mode. If None, will use GRADIO_SSR_MODE
environment variable or default to False.
pwa: bool | None
default `= None`
If True, the Gradio app will | launch | https://gradio.app/docs/gradio/blocks | Gradio - Blocks Docs |
rendered
using client-side rendering mode. If None, will use GRADIO_SSR_MODE
environment variable or default to False.
pwa: bool | None
default `= None`
If True, the Gradio app will be set up as an installable PWA (Progressive Web
App). If set to None (default behavior), then the PWA feature will be enabled
if this Gradio app is launched on Spaces, but not otherwise.
mcp_server: bool | None
default `= None`
If True, the Gradio app will be set up as an MCP server and documented
functions will be added as MCP tools. If None (default behavior), then the
GRADIO_MCP_SERVER environment variable will be used to determine if the MCP
server should be enabled.
i18n: I18n | None
default `= None`
An I18n instance containing custom translations, which are used to translate
strings in our components (e.g. the labels of components or Markdown strings).
This feature can only be used to translate static text in the frontend, not
values in the backend.
theme: Theme | str | None
default `= None`
A Theme object or a string representing a theme. If a string, will look for a
built-in theme with that name (e.g. "soft" or "default"), or will attempt to
load a theme from the Hugging Face Hub (e.g. "gradio/monochrome"). If None,
will use the Default theme.

Custom html code to insert into the head of the demo webpage. This can be used
to add custom meta tags, multiple scripts, stylesheets, etc. to the page.
head_paths: str | Path | list[str | Path] | None
default `= None`
Custom html code as a pathlib.Path to a html file or a list of such paths.

Parameters ▼
status_update_rate: float | Literal['auto']
default `= "auto"`
If "auto", Queue will send status estimations to all clients whenever a job is
finished. Otherwise Queue will send status at regular intervals set by this
parameter as the number of seconds.
api_open: | queue | https://gradio.app/docs/gradio/blocks | Gradio - Blocks Docs |
will send status estimations to all clients whenever a job is
finished. Otherwise Queue will send status at regular intervals set by this
parameter as the number of seconds.
api_open: bool | None
default `= None`
If True, the REST routes of the backend will be open, allowing requests made
directly to those endpoints to skip the queue.
max_size: int | None
default `= None`
The maximum number of events the queue will store at any given moment. If the
queue is full, new events will not be added and a user will receive a message
saying that the queue is full. If None, the queue size will be unlimited.
default_concurrency_limit: int | None | Literal['not_set']
default `= "not_set"`
The default value of `concurrency_limit` to use for event listeners that don't
specify a value. Can be set by environment variable
GRADIO_DEFAULT_CONCURRENCY_LIMIT. Defaults to 1 if not set otherwise.

This listener is triggered when the Blocks initially loads in the browser.
Parameters ▼
block: Block | None
fn: Callable | None | Literal['decorator']
default `= "decorator"`
the function to call when this event is triggered. Often a machine learning
model's prediction function. Each parameter of the function corresponds to one
input component, and the function should return a single value or a tuple of
values, with each element in the tuple corresponding to o | load | https://gradio.app/docs/gradio/blocks | Gradio - Blocks Docs |
ction function. Each parameter of the function corresponds to one
input component, and the function should return a single value or a tuple of
values, with each element in the tuple corresponding to one output component.
inputs: Component | BlockContext | list[Component | BlockContext] | Set[Component | BlockContext] | None
default `= None`
List of gradio.components to use as inputs. If the function takes no inputs,
this should be an empty list.
outputs: Component | BlockContext | list[Component | BlockContext] | Set[Component | BlockContext] | None
default `= None`
List of gradio.components to use as outputs. If the function returns no
outputs, this should be an empty list.
api_name: str | None
default `= None`
defines how the endpoint appears in the API docs. Can be a string or None. If
set to a string, the endpoint will be exposed in the API docs with the given
name. If None (default), the name of the function will be used as the API
endpoint.
api_description: str | None | Literal[False]
default `= None`
Description of the API endpoint. Can be a string, None, or False. If set to a
string, the endpoint will be exposed in the API docs with the given
description. If None, the function's docstring will be used as the API
endpoint description. If False, then no description will be displayed in the
API docs.
scroll_to_output: bool
default `= False`
If True, will scroll to output component on completion
show_progress: Literal['full', 'minimal', 'hidden']
default `= "full"`
how to show the progress animation while event is running: "full" shows a
spinner which covers the output component area as well as a runtime display in
the upper right corner, "minimal" only shows the runtime display, "hidden"
shows no progress animation at all
show_progress_on: Component | list[Component] | None
default `= None`
Component or list of components to show the pro | load | https://gradio.app/docs/gradio/blocks | Gradio - Blocks Docs |
the runtime display, "hidden"
shows no progress animation at all
show_progress_on: Component | list[Component] | None
default `= None`
Component or list of components to show the progress animation on. If None,
will show the progress animation on all of the output components.
queue: bool
default `= True`
If True, will place the request on the queue, if the queue has been enabled.
If False, will not put this event on the queue, even if the queue has been
enabled. If None, will use the queue setting of the gradio app.
batch: bool
default `= False`
If True, then the function should process a batch of inputs, meaning that it
should accept a list of input values for each parameter. The lists should be
of equal length (and be up to length `max_batch_size`). The function is then
*required* to return a tuple of lists (even if there is only 1 output
component), with each list in the tuple corresponding to one output component.
max_batch_size: int
default `= 4`
Maximum number of inputs to batch together if this is called from the queue
(only relevant if batch=True)
preprocess: bool
default `= True`
If False, will not run preprocessing of component data before running 'fn'
(e.g. leaving it as a base64 string if this method is called with the `Image`
component).
postprocess: bool
default `= True`
If False, will not run postprocessing of component data before returning 'fn'
output to the browser.
cancels: dict[str, Any] | list[dict[str, Any]] | None
default `= None`
A list of other events to cancel when this listener is triggered. For example,
setting cancels=[click_event] will cancel the click_event, where click_event
is the return value of another components .click method. Functions that have
not yet run (or generators that are iterating) will be cancelled, but
functions that are currently running will be allowed to finish.
trigger_mode: | load | https://gradio.app/docs/gradio/blocks | Gradio - Blocks Docs |
s .click method. Functions that have
not yet run (or generators that are iterating) will be cancelled, but
functions that are currently running will be allowed to finish.
trigger_mode: Literal['once', 'multiple', 'always_last'] | None
default `= None`
If "once" (default for all events except `.change()`) would not allow any
submissions while an event is pending. If set to "multiple", unlimited
submissions are allowed while pending, and "always_last" (default for
`.change()` and `.key_up()` events) would allow a second submission after the
pending event is complete.
js: str | Literal[True] | None
default `= None`
Optional frontend js method to run before running 'fn'. Input arguments for js
method are values of 'inputs' and 'outputs', return should be a list of values
for output components.
concurrency_limit: int | None | Literal['default']
default `= "default"`
If set, this is the maximum number of this event that can be running
simultaneously. Can be set to None to mean no concurrency_limit (any number of
this event can be running simultaneously). Set to "default" to use the default
concurrency limit (defined by the `default_concurrency_limit` parameter in
`Blocks.queue()`, which itself is 1 by default).
concurrency_id: str | None
default `= None`
If set, this is the id of the concurrency group. Events with the same
concurrency_id will be limited by the lowest set concurrency_limit.
api_visibility: Literal['public', 'private', 'undocumented']
default `= "public"`
controls the visibility and accessibility of this endpoint. Can be "public"
(shown in API docs and callable by clients), "private" (hidden from API docs
and not callable by clients), or "undocumented" (hidden from API docs but
callable by clients and via gr.load). If fn is None, api_visibility will
automatically be set to "private".
time_limit: int | None
default `= None`
stream_every: | load | https://gradio.app/docs/gradio/blocks | Gradio - Blocks Docs |
s but
callable by clients and via gr.load). If fn is None, api_visibility will
automatically be set to "private".
time_limit: int | None
default `= None`
stream_every: float
default `= 0.5`
key: int | str | tuple[int | str, ...] | None
default `= None`
A unique key for this event listener to be used in @gr.render(). If set, this
value identifies an event as identical across re-renders when the key is
identical.
validator: Callable | None
default `= None`
Optional validation function to run before the main function. If provided,
this function will be executed first with queue=False, and only if it
completes successfully will the main function be called. The validator
receives the same inputs as the main function and should return a
`gr.validate()` for each input value.

Gradio includes pre-built components that can be used as inputs or outputs
in your Interface or Blocks with a single line of code. Components include
preprocessing steps that convert user data submitted through browser to
something that be can used by a Python function, and postprocessing steps to
convert values returned by a Python function into something that can be
displayed in a browser.
Consider an example with three inputs (Textbox, Number, and Image) and two
outputs (Number and Gallery), below is a diagram of what our preprocessing
will send to the function and what our postprocessing will require from it.

Components also come with certain events that they support. These are
methods that are triggered with user actions. Below is a table showing which
events are supported for each component. All events are also listed (with
parameters) in the component’s docs.

Creates an image component that can be used to upload images (as an input)
or display images (as an output).
| Description | https://gradio.app/docs/gradio/image | Gradio - Image Docs |
**Using Image as an input component.**
How Image will pass its value to your function:
Type: `np.ndarray | PIL.Image.Image | str | None`
Passes the uploaded image as a `numpy.array`, `PIL.Image` or `str` filepath
depending on `type`.
Example Code
import gradio as gr
def predict(
value: np.ndarray | PIL.Image.Image | str | None
):
process value from the Image component
return "prediction"
interface = gr.Interface(predict, gr.Image(), gr.Textbox())
interface.launch()
**Using Image as an output component**
How Image expects you to return a value:
Type: `np.ndarray | PIL.Image.Image | str | Path | None`
Expects a `numpy.array`, `PIL.Image`, or `str` or `pathlib.Path` filepath to
an image which is displayed.
Example Code
import gradio as gr
def predict(text) -> np.ndarray | PIL.Image.Image | str | Path | None
process value to return to the Image component

Parameters ▼
value: str | PIL.Image.Image | np.ndarray | Callable | None
default `= None`
A `PIL.Image`, `numpy.array`, `pathlib.Path`, or `str` filepath or URL for the
default value that Image component is going to take. If a function is
provided, the function will be called each time the app loads to set the
initial value of this component.
format: str
default `= "webp"`
File format (e.g. "png" or "gif"). Used to save image if it does not already
have a valid format (e.g. if the image is being returned to the frontend as a
numpy array or PIL Image). The format should be supported by the PIL library.
Applies both when this component is used as an input or output. This parameter
has no effect on SVG files.
height: int | str | None
default `= None`
The height of the component, specified in pixels if a number is passed, or in
CSS units if a string is passed. This has no effect on the preprocessed image
file or numpy array, but will affect the displayed image.
width: int | str | None
default `= None`
The width of the component, specified in pixels if a number is passed, or in
CSS units if a string is passed. This has no effect on the preprocessed image
file or numpy array, but will affect the displayed image.
image_mode: Literal['1', 'L', 'P', 'RGB', 'RGBA', 'CMYK', 'YCbCr', 'LAB', 'HSV', 'I', 'F'] | None
default `= "RGB"`
The pixel format and color depth that the image should be loaded and
preprocessed as. "RGB" will load the image as a color image, or "L" as black-
and-white. See https://pillow.readthedocs.io/en/stable/handbook/concepts.html
for other supported image modes and their meaning. This parameter has no
effect on SVG or GIF files. If set to None, the image_mode will be inferred
from the image file type (e.g. "RGBA" for a .png image, "RGB" in most other
cases).
sources: list[Literal['upload', 'webcam', 'clipboard']] | Literal['upload', 'webcam', 'clipboa | Initialization | https://gradio.app/docs/gradio/image | Gradio - Image Docs |
erred
from the image file type (e.g. "RGBA" for a .png image, "RGB" in most other
cases).
sources: list[Literal['upload', 'webcam', 'clipboard']] | Literal['upload', 'webcam', 'clipboard'] | None
default `= None`
List of sources for the image. "upload" creates a box where user can drop an
image file, "webcam" allows user to take snapshot from their webcam,
"clipboard" allows users to paste an image from the clipboard. If None,
defaults to ["upload", "webcam", "clipboard"] if streaming is False, otherwise
defaults to ["webcam"].
type: Literal['numpy', 'pil', 'filepath']
default `= "numpy"`
The format the image is converted before being passed into the prediction
function. "numpy" converts the image to a numpy array with shape (height,
width, 3) and values from 0 to 255, "pil" converts the image to a PIL image
object, "filepath" passes a str path to a temporary file containing the image.
To support animated GIFs in input, the `type` should be set to "filepath" or
"pil". To support SVGs, the `type` should be set to "filepath".
label: str | I18nData | None
default `= None`
the label for this component. Appears above the component and is also used as
the header if there are a table of examples for this component. If None and
used in a `gr.Interface`, the label will be the name of the parameter this
component is assigned to.
every: Timer | float | None
default `= None`
Continously calls `value` to recalculate it if `value` is a function (has no
effect otherwise). Can provide a Timer whose tick resets `value`, or a float
that provides the regular interval for the reset Timer.
inputs: Component | list[Component] | set[Component] | None
default `= None`
Components that are used as inputs to calculate `value` if `value` is a
function (has no effect otherwise). `value` is recalculated any time the
inputs change.
show_label: bool | None
default `= None`
if True, will disp | Initialization | https://gradio.app/docs/gradio/image | Gradio - Image Docs |
calculate `value` if `value` is a
function (has no effect otherwise). `value` is recalculated any time the
inputs change.
show_label: bool | None
default `= None`
if True, will display label.
buttons: list[Literal['download', 'share', 'fullscreen'] | Button] | None
default `= None`
A list of buttons to show in the corner of the component. Valid options are
"download", "share", "fullscreen", or a gr.Button() instance. The "download"
button allows the user to download the image. The "share" button allows the
user to share to Hugging Face Spaces Discussions. The "fullscreen" button
allows the user to view in fullscreen mode. Custom gr.Button() instances will
appear in the toolbar with their configured icon and/or label, and clicking
them will trigger any .click() events registered on the button. by default,
all of the built-in buttons are shown.
container: bool
default `= True`
If True, will place the component in a container - providing some extra
padding around the border.
scale: int | None
default `= None`
relative size compared to adjacent Components. For example if Components A and
B are in a Row, and A has scale=2, and B has scale=1, A will be twice as wide
as B. Should be an integer. scale applies in Rows, and to top-level Components
in Blocks where fill_height=True.
min_width: int
default `= 160`
minimum pixel width, will wrap if not sufficient screen space to satisfy this
value. If a certain scale value results in this Component being narrower than
min_width, the min_width parameter will be respected first.
interactive: bool | None
default `= None`
if True, will allow users to upload and edit an image; if False, can only be
used to display images. If not provided, this is inferred based on whether the
component is used as an input or output.
visible: bool | Literal['hidden']
default `= True`
If False, component will be hidden. If "hidd | Initialization | https://gradio.app/docs/gradio/image | Gradio - Image Docs |
ovided, this is inferred based on whether the
component is used as an input or output.
visible: bool | Literal['hidden']
default `= True`
If False, component will be hidden. If "hidden", component will be visually
hidden and not take up space in the layout but still exist in the DOM
streaming: bool
default `= False`
If True when used in a `live` interface, will automatically stream webcam
feed. Only valid is source is 'webcam'. If the component is an output
component, will automatically convert images to base64.
elem_id: str | None
default `= None`
An optional string that is assigned as the id of this component in the HTML
DOM. Can be used for targeting CSS styles.
elem_classes: list[str] | str | None
default `= None`
An optional list of strings that are assigned as the classes of this component
in the HTML DOM. Can be used for targeting CSS styles.
render: bool
default `= True`
If False, component will not render be rendered in the Blocks context. Should
be used if the intention is to assign event listeners now but render the
component later.
key: int | str | tuple[int | str, ...] | None
default `= None`
in a gr.render, Components with the same key across re-renders are treated as
the same component, not a new component. Properties set in 'preserved_by_key'
are not reset across a re-render.
preserved_by_key: list[str] | str | None
default `= "value"`
A list of parameters from this component's constructor. Inside a gr.render()
function, if a component is re-rendered with the same key, these (and only
these) parameters will be preserved in the UI (if they have been changed by
the user or an event listener) instead of re-rendered based on the values
provided during constructor.
webcam_options: WebcamOptions | None
default `= None`
placeholder: str | None
default `= None`
Custom text for the upload area. Overri | Initialization | https://gradio.app/docs/gradio/image | Gradio - Image Docs |
