# MapEval-Visual

This dataset was introduced in [MapEval](https://arxiv.org/abs/2501.00316)

## Prerequisite

Download the [Vdata.zip](https://huggingface.co/datasets/MapEval/MapEval-Visual/resolve/main/Vdata.zip?download=true) and extract in the working directory. This directory contains all the images.

## Usage
```python
from datasets import load_dataset
import PIL.Image
# Load dataset
ds = load_dataset("MapEval/MapEval-Visual", name="benchmark")

for item in ds["test"]:
   
    # Start with a clear task description
    prompt = (
        "You are a highly intelligent assistant. "
        "Based on the given image, answer the multiple-choice question by selecting the correct option.\n\n"
        "Question:\n" + item["question"] + "\n\n"
        "Options:\n"
    )
    
    # List the options more clearly
    for i, option in enumerate(item["options"], start=1):
        prompt += f"{i}. {option}\n"
    
    # Add a concluding sentence to encourage selection of the answer
    prompt += "\nSelect the best option by choosing its number."
    
    # Load image from Vdata/ directory
    img = PIL.Image.open(item["context"])
    
    # Use the prompt as needed
    print([prompt, img])  # Replace with your processing logic
```
