LATIN-Prompt

Layout and Task Aware Instruction Prompt for Zero-shot Document Image Question Answering

News

• 2024.05.28: We release the instruction-tuning data for LATIN-Tuning.
• 2023.09.07: We support the Llama2 and Llama2-chat models.
• 2023.09.06: We introduce LATIN-Tuning for Alpaca, which enhances its zero-shot performance on DocVQA from 0.3567 to 0.6697.
• 2023.06.30: We now provide implementations based on Azure OpenAI text-davinci-003 Completion.
• 2023.06.29: We now provide implementations based on Alpaca-7B and Vicuna-13B.

Preparation

Prepare the environment

pip install -r requirements.txt

Set environment variable for Cluade and OpenAI

Set the ANTHROPIC_API_KEY for Cluade. Please refer to the script ./utils/claude.py.

export ANTHROPIC_API_KEY="Your API key"

Set the OPENAI_API_KEY and OPENAI_API_BASE for Azure OpenAI. Please refer to the script ./utils/openai_api.py. For the differences between Azure OpenAI and OpenAI, see here.

export OPENAI_API_KEY="Your API key"
export OPENAI_API_BASE="Your base url"

Note: Currently, due to resource constraints, our experiments are all based on the Azure OpenAI API. At the same time, we are working hard to seek access to official OpenAI API. If you can provide relevant resources, please contact the author and we will be very grateful.

Set environment variable for data directory

export DATAS_DIR="Your data directory"

Prepare the dataset

• Download DocVQA dataset with Azure OCR results from DUE Benchmark and put it into the DATAS_DIR.
• Download DocVQA dataset with Official OCR results from Robust Reading Competition and put it into the DATAS_DIR.

Set the path of model checkpoints

Refer to the script ./utils/model_path_config.py.
