Multimodal Chain-of-Thought Reasoning in Language Models
"Imagine learning a textbook without figures or tables."
Multimodal-CoT incorporates vision features in a decoupled training framework. The framework consists of two training stages: (i) rationale generation and (ii) answer inference. Both stages share the same model architecture but differ in the input and output.
Requirements
Install all required python dependencies:
pip install -r requirements.txt
Datasets
Download the dataset from the following repository:
https://github.com/lupantech/ScienceQA/tree/main/data
Download the extracted vision features from vision_features and unzip the files under vision_features

Inference
Our trained models are available at models. To use our trained models, please put the them under the models folder.
