LLMSanitize

An open-source library for contamination detection in NLP datasets and Large Language Models (LLMs).

Installation

The library has been designed and tested with Python 3.9 and CUDA 11.8.

First make sure you have CUDA 11.8 installed, and create a conda environment with Python 3.9:

conda create --name llmsanitize python=3.9

Next activate the environment:

conda activate llmsanitize

Then install LLMSanitize from PyPI:

pip install llmsanitize

Notably, we use vllm 0.3.3.

The repository supports all the following contamination detection methods:

vLLM

The following methods require to launch a vLLM instance which will handle model inference:

Method
guided-prompting
min-prob
cdd
ts-guessing-question-based
ts-guessing-question-multichoice

To launch the instance, first run the following command in a terminal:

sh llmsanitize/scripts/vllm_hosting.sh

You are required to specify a port number and model name in this shell script.

Run Contamination Detection

To run contamination detection, you can follow the multiple test scripts in scripts/tests/ folder.

For instance, to run sharded-likelihood on Hellaswag with Llama-2-7B:

sh llmsanitizescripts/tests/closed_data/sharded-likelihood/test_hellaswag.sh -m <path_to_your_llama-2-7b_folder> 

To run a method using vLLM like guided-prompting for instance, the only difference is to pass the port number as argument:

sh llmsanitizescripts/tests/closed_data/guided-prompting/test_hellaswag.sh -m <path_to_your_llama-2-7b_folder> -p <port_number_from_your_vllm_instance>

Or, since llmsanitize has been installed as a Python package, you can call the detection methods directly in your Python script:

from llmsanitize ClosedDataContaminationChecker
args = <setup your argparse here>
contamination_checker = ClosedDataContaminationChecker(args)
contamination_checker.run_contamination("guided-prompting") # make sure that your args contain all parameters relevant this specific method
