Data Format

All train datasets follow a unified format:

{
    "images": [PIL.Image],           # List of images                           
    "question": str,                 # Question text
    "options": Dict[str, str],       # Multiple choice options
    "answer_label": str,             # Correct answer label (A, B, C, D, E)
    "answer": str,                   # Full answer text
    "reasoning": str,                # Chain-of-thought reasoning (optional)
    "dataset_name": str,             # Source dataset name
    "dataset_index": int             # Unique sample identifier
