Questions about replication experiments.

Are the code and parameters in this repository consistent with the parameters used in the experiments described in the paper? I conducted an experiment on an A100 using the provided command "bash 10_optimize_rotation.sh meta-llama/Llama-2-7b 4 4 4" keeping the parameters unchanged in the script. However, the results I obtained differ somewhat from the results reported in the paper.
This is my command "bash 10_optimize_rotation.sh meta-llama/Llama-2-7b 4 4 4", and I only change the nproc_per_node to 1. When I use the eval command "2_eval_ptq.sh $model_name 4 4 4", the ppl is about 8.49.
The model I use is NousResearch/Llama-2-7b-chat-hf.
