🧑‍💻 How to Run?

🏠 Set Up

Dataset Download

Download tsv files from HuggingFace and store them in data/tsv/. The directory should be like data/tsv/{DATASET}_{SETTING}_{LANGUAGE}.tsv.

Environment Configuration

conda create -n pm4bench python=3.10.5
conda activate pm4bench
pip install -r requirements.txt

⚙️ Inference

API Inference

Step 0. Configure .env file

API inference requires an API_KEY. Please configure the API_KEY in the .env file in the following format:

gpt-4o-2024-11-20='xxx'
step-1o-vision-32k='xxx'
qwen2.5-vl-72b-instruct='xxx'
gemini-2.0-flash-thinking-exp='xxx'
DeepSeek-R1='xxx'
gpt-4o-mini='xxx'

The API_KEY will be loaded through the infer_api.py file using:

load_dotenv()  # load .env file to get API_KEY
API_KEY = os.getenv(MODEL)

Step 1. Start Inference!

🔴 Attention: All codes and scripts files are executed in the root directory! e.g. python code/infer_api.py [MODEL] [MODE] [SETTING] [LANGUAGE] [TASK] [DATASET] [MAX_TOKENS]

• MODEL: Official model name, such as gpt-4o-2024-11-20, qwen2.5-vl-72b-instruct, etc.
• MODE: For normal VLMs, use direct; for reasoning VLMs, use cot.
• SETTING: traditional or vision, for detailed explanations please refer to our paper.
• LANGUAGE: 10 languages choices, [ZH, EN, AR, SR, TH, RU, KO, CS, HU, VI]
• TASK: OCR for OCR tasks, and VQA for VQA tasks under traditional or vision settings.
• DATASET: [MDUR, MIQA, MMJB, MSOCR]
• MAX_TOKENS: For different models, the MAX_TOKENS should be different in case of cut off problems.

Besides, we provide a standard script template scripts/infer_api.sh. You can modify parameters directly and run it using

nohup bash scripts/infer_api.sh > logs/infer_api.log 2>&1 &

Local VLMs Inference

Step 0. Use LMDeploy to serve models

A special thanks to LMDeploy for their work, which has greatly assisted in providing local inference for our work. Please refer to LMDeploy docs for detailed information of VLMs' deployment and serve. Before inference, you should make sure that VLM is running and you have a local port (like 23333) to call it:

CUDA_VISIBLE_DEVICES=$CUDA_DEVICES nohup lmdeploy serve api_server $MODEL_PATH 
--backend turbomind --dtype $DTYPE --server-port $SERVER_PORT --tp $TP > $LOG_PATH 2>&1 &

We only provide a simplified command line here and if you want to know more paramters and their meanings, please run

lmdeploy serve api_server --help

Step 1. Start Inference!

🔴 Attention: All codes and scripts files are executed in the root directory! e.g. python code/infer_lmdeploy.py [MODEL] [MODE] [SETTING] [LANGUAGE] [TASK] [DATASET] [MAX_TOKENS] [PORT]

• MODEL: Model name, such as InternVL2_5-78B-MPO, qwen2.5-vl-72b-instruct, etc.
• MODE: For normal VLMs, use direct; for reasoning VLMs, use cot.
• SETTING: traditional or vision, for detailed explanations please refer to our paper.
• LANGUAGE: 10 languages choices, [ZH, EN, AR, SR, TH, RU, KO, CS, HU, VI]
• TASK: OCR for OCR tasks, and VQA for VQA tasks under traditional or vision settings.
• DATASET: [MDUR, MIQA, MMJB, MSOCR]
• MAX_TOKENS: For different models, the MAX_TOKENS should be different in case of cut off problems.
• PORT: Local port (like 23333) for lmdeploy server to call.

Besides, we provide a standard script template scripts/infer_lmdeploy.sh. You can modify parameters directly and run it using

nohup bash scripts/infer_lmdeploy.sh > logs/infer_lmdeploy.log 2>&1 &

📉 Evaluation & Statistics

Step 0. Evaluation

We use gpt-4o-2024-11-20 to judge VQA performance so you should configure API_KEY before evaluation. Besides, you can change base model in code/eval/{DATASET}/eval_{DATASET}_vqa.py:

OPENAI_API_BASE = "https://api.openai.com/v1"
client = OpenAI(
    api_key = os.getenv('gpt-4o-2024-11-20'),
    base_url = OPENAI_API_BASE
)

The evaluation codes are executed by:

python code/eval/{DATASET}/eval_{DATASET}_{TASK}.py

where DATASET is chosen from [MDUR, MIQA, MMJB, MSOCR] and TASK is chosen from [VQA, OCR].

Step 1. Statistics

The statistics codes are executed by:

python code/score.py

and the results are stored in data/results/{DATASET}_{TASK}_{SETTING}.csv
