RankLLM

We offer a suite of prompt decoders, albeit with a current focus on RankVicuna. Some of the code in this repository is borrowed from RankGPT!

Releases

current_version = 0.2.3

📟 Instructions

Create Conda Environment

conda create -n rankllm python=3.10
conda activate rankllm

Install Pytorch with CUDA
