Mistake in the preparation of vicuna weights (error when loading delta weights) about minigpt-4 HOT 7 OPEN

Change "tokenizer_class": "LLaMATokenizer" in llama-13b-hf/tokenizer_config.json into "tokenizer_class": "LlamaTokenizer". It worked for me~

I have ever seen this issue in here, see that if this can help you?

I still met this issue and I chacked it's "Llama"

You should probably TRAIN this model on a down-stream task to be able to use it for predictions and inference.

I have observed that a few seconds before the error occurred, the memory usage suddenly spiked to 60GB out of my total 64GB memory. I suspect this issue might be related to the memory consumption. Could you please provide some guidance or suggestions on how to handle this situation? Thank you in advance. @gch8295322

Dear @gch8295322

Thank you for your help earlier. I have prepared the model, but I am still encountering the "TypeError: argument of type 'WindowsPath' is not iterable" issue. I noticed that this problem is also being discussed in #28. I would like to ask if there is a solution to this issue at the moment? Once again, thank you for your assistance.

Best regards

@Wenbobobo
that's wield, I changed the class name and it works, maybe you should just reboot the terminal?
