[SOLVED] FineTune llama3 model with torch tune gives error

Im trying to fine tune the llama3 model with torch tune.

these are the steps that ive already done :

1.pip install torch
2.pip install torchtune
3.tune download meta-llama/Meta-Llama-3-8B --output-dir llama3 --hf-token ***(my token)***
4.tune run lora_finetune_single_device --config llama3/8B_lora_single_device device="cpu"

and then this error happens:

should i copy the original folder from llama3 download path to /tmp folder ? its like 16g model. Can i gave the already downloaded model path to tune ?
