The instructions to install Llama3 is horrible

[Eyesun23]

I followed the steps of getting access to the models; I received a link. But I am getting this error after I ran:

torchrun --nproc_per_node=1 example_chat_completion.py \ --ckpt_dir Meta-Llama-3-8B-Instruct/ \ --tokenizer_path Meta-Llama-3-8B-Instruct/tokenizer.model \ --max_seq_len 512 --max_batch_size 6

I suspect the issue lies in the first line: ‘’/opt/anaconda3/envs/llama3/bin/python: can't open file 'example_chat_completion.py': [Errno 2] No such file or directory‘’，you can check if there is any problem with the file path when you run this command.
