I am trying to evaluate the perplexity of Llama-2 13b on WikiText-2.

When using the script from GitHub - yxli2123/LoftQ, I get a perplexity of 12.02.

However when using the code from this repo I get a value of 5.43. I get the same value when using GitHub - locuslab/wanda: A simple and effective LLM pruning approach..

What is the reason for the large difference?
