How to Evaluate Large Vision-Language Models with VLMEvalKit

Dec 6, 2020 | Data Science

Welcome to the guide on leveraging VLMEvalKit, an open-source evaluation toolkit designed specifically for Large Vision-Language Models (LVLMs). This toolkit simplifies the benchmarking process by allowing users to evaluate models with just a single command, enabling efficiency and accuracy in research and development.

Understanding VLMEvalKit

Think of VLMEvalKit as a Swiss Army knife for evaluating large-scale AI models. Just like the versatility of a Swiss Army knife in tackling various tasks, VLMEvalKit is equipped to handle multiple evaluation benchmarks without the headache of managing extensive data preparation or multiple repositories. It supports generation-based evaluation and provides results using both exact matching and LLM-based answer extraction.

Quickstart Guide

Getting started with VLMEvalKit is straightforward. Here’s how you can do it:

  • Ensure you have Python installed on your system.
  • Install VLMEvalKit using pip:
  • pip install vlmeval
  • Import the required modules:
  • from vlmeval.config import supported_VLM
  • Select the model you wish to work with:
  • model = supported_VLM[idefics_9b_instruct]()
  • Feed an image for evaluation:
  • ret = model.generate(['assets/apple.jpg', 'What is in this image?'])
  • Print the result
  • print(ret)

The Goal of VLMEvalKit

The primary objectives of VLMEvalKit are:

  • To provide an easily accessible evaluation toolkit for researchers and developers.
  • To facilitate the evaluation of LVLMs across various benchmarks with minimal setup.
  • To enhance reproducibility of evaluation results in the field.

Troubleshooting Tips

Should things not go as planned, or if you run into issues during the setup or execution process, consider the following troubleshooting ideas:

  • Ensure Dependencies Are Met: Make sure that your installed transformers and torchvision libraries match the recommended versions.
  • Check Image Paths: Make sure the paths to your images are correct and accessible by the script.
  • Review Error Messages: Read through any output error messages carefully to identify what might have gone wrong.
  • If you continue to experience issues, don’t hesitate to seek help or check for updates on the VLMEvalKit Discord.
  • For more insights, updates, or to collaborate on AI development projects, stay connected with fxis.ai.
