Prepare data

Run prepare_dataset to create a similarity dataset with one postive and negative pair from SNLI.

python prepare_dataset.py

Run model

set the model cache folder export TRANSFORMERS_CACHE=.cache/

First, run accelerate config --config_file ds_zero3_cpu.yaml

check the sample file for Single GPU here
