print(result)PPOCRV6SmallRecForTextRecognition
class transformers.PPOCRV6SmallRecForTextRecognition
< source >( config: PPOCRV6SmallRecConfig )
Parameters
- config (PPOCRV6SmallRecConfig) — Model configuration class with all the parameters of the model. Initializing with a config file does not load the weights associated with the model, only the configuration. Check out the from_pretrained() method to load the model weights.
PPOCR6SmallRec model for text recognition tasks.
This model inherits from PreTrainedModel. Check the superclass documentation for the generic methods the library implements for all its model (such as downloading or saving, resizing the input embeddings, pruning heads etc.)
This model is also a PyTorch torch.nn.Module subclass. Use it as a regular PyTorch Module and refer to the PyTorch documentation for all matter related to general usage and behavior.
forward
< source >( pixel_values: FloatTensor **kwargs: typing_extensions.Unpack[transformers.utils.generic.TransformersKwargs] ) → BaseModelOutputWithNoAttention or tuple(torch.FloatTensor)
Parameters
- pixel_values (
torch.FloatTensorof shape(batch_size, num_channels, image_size, image_size)) — The tensors corresponding to the input images. Pixel values can be obtained using PPOCRV6SmallRecImageProcessor. SeePPOCRV6SmallRecImageProcessor.__call__()for details (processor_classuses PPOCRV6SmallRecImageProcessor for processing images).
Returns
BaseModelOutputWithNoAttention or tuple(torch.FloatTensor)
A BaseModelOutputWithNoAttention or a tuple of
torch.FloatTensor (if return_dict=False is passed or when config.return_dict=False) comprising various
elements depending on the configuration (PPOCRV6SmallRecConfig) and inputs.
The PPOCRV6SmallRecForTextRecognition forward method, overrides the __call__ special method.
Although the recipe for forward pass needs to be defined within this function, one should call the
Moduleinstance afterwards instead of this since the former takes care of running the pre and post processing steps while the latter silently ignores them.
last_hidden_state (
torch.FloatTensorof shape(batch_size, num_channels, height, width)) — Sequence of hidden-states at the output of the last layer of the model.hidden_states (
tuple(torch.FloatTensor), optional, returned whenoutput_hidden_states=Trueis passed or whenconfig.output_hidden_states=True) — Tuple oftorch.FloatTensor(one for the output of the embeddings, if the model has an embedding layer, + one for the output of each layer) of shape(batch_size, num_channels, height, width).Hidden-states of the model at the output of each layer plus the optional initial embedding outputs.

float, optional, defaults to2.0) — Ratio of the MLP hidden dim to the embedding dim. - depth (
int, optional, defaults to2) — Number of Transformer layers in the vision encoder. - head_out_channels (
int, optional, defaults to 18714) — The number of output channels from the PPOCRV6SmallRecHead, responsible for final classification. - conv_kernel_size (
list, optional) — The size of the convolutional kernel. - qkv_bias (
bool, optional, defaults toTrue) — Whether to add a bias to the queries, keys and values. - num_attention_heads (

This is the configuration class to store the configuration of a PPOCRV6SmallRecModel. It is used to instantiate a Pp Ocrv6 Small Rec model according to the specified arguments, defining the model architecture. Instantiating a configuration with the defaults will yield a similar configuration to that of the PaddlePaddle/PP-OCRv6_small_rec_safetensors
Configuration objects inherit from PreTrainedConfig and can be used to control the model outputs. Read the documentation from PreTrainedConfig for more information.
