How to arrange the file ‘models’？？？

[LensGrinder4E00]

I have downloaded all the models mentioned in the README, and for one model, I've created a special folder for it, like "CodeT5-large/". But when I run the script 'generate.sh', I received the “ValueError: Connection error, and we cannot find the requested files in the cached path. Please try again or make sure your Internet connection is on.” for this line： tokenizer = RobertaTokenizer.from_pretrained('Salesforce/codet5-base', cache_dir=args.tokenizer_path)

Is there anyone can teach me how to arrange the models in the folder 'models'？？
