siddeo99/job_search_finetune

Fine-Tuned Llama 2 model for Multilingual Text Generation

This repository contains adapters for the adapter-transformers library aimed at enabling multilingual text generation. It leverages datasets such as siddeo99/sidtestfiverrmulti and supports multiple languages including English, Hindi, and Punjabi.

Installation

To install the necessary library, you can use pip:

!pip install -q accelerate==0.21.0 peft==0.4.0 bitsandbytes==0.40.2 transformers==4.31.0 trl==0.4.7
!pip install pyarrow

This Section is for GPU enabled devices(For cpu code is below,skip the below code for cpu)
