Evaluation Results

✅ Evaluation Instructions

ChartQAPro is supported in VLMEvalKit, the standard evaluation toolkit for Vision–Language Models.
We strongly recommend using VLMEvalKit for consistent and reproducible evaluation.
🔗 https://github.com/open-compass/VLMEvalKit

To evaluate your model on ChartQAPro using our repo codebase (NOT RECOMMENDED), follow the steps below:

1. Format Your Predictions

Save your model's predictions in a .json file that contains a list of dictionaries.
Each dictionary should include the following keys (first three keys taken from the original huggingface dataset):

• "Answer": the ground truth answer
• "Question Type": the type of the question (e.g., Factoid, MCQ, etc.)
• "Year": useful for evaluating year-based answers
• "prediction": your model’s predicted answer

📝 Example Format

[
  {
    "Answer": ["2016"]
    "Question Type": "Factoid",
    "Year": ["YES"]
    "prediction": "2016"
  },
  ...
]

2. Install Required Dependencies

pip install anls pandas

3. Run the Evaluation Script

python evaluate_predictions.py --predictions-file path/to/your/predictions.json

This will print your model’s performance across different question types and the overall score, following the official evaluation metrics used in the paper. 📊
