I’m trying to use autotrain to fine-tune a llama 2 7b base model. I’m trying to use the ChatUI module to use my trained model and it fails. To narrow the issue I tried to use the same ChatUI space with the original base llama-2-7b model but got the same error so it looks like the issue is with the ChatUI config not the fine-tuning part. Here’s the error I’m getting when ChatUI it built:

Traceback (most recent call last):

Note that I do have access to the llama 2 model.  
Any help will be much appreciated.
