Hello everyone, thank you for the great job!

I am trying to further fine-tune the LLaVA architecture using your implementation with LLaMA 3 Instruct 8B. I can already fine-tune the Vicuna model using the original LLaVA code and now I am looking for some implementation with LLaMA 3.

I found your repo and followed your instructions from the README.md file for each step. I am able to train the model using the following bash file and it looks like it's correctly saved. NOTE: I downloaded the model from your huggingface repo

I then tried to merge (using this script from LLaVA) the resulting adapters with the original model LLaVA-Meta-Llama-3-8B-Instruct-FT and I got the following error.

Special tokens have been added in the vocabulary, make sure the associated word embeddings are fine-tuned or trained.

Finally, I even tried using the adapters (without merging) with the following script but I get the same identical error. The file llava/eval/test_llava.py is very similar to the inference script from the original LLaVA repo, but I made very little changes for my convenience (such as --prompt-version, --input-file-path, etc.).

Do you have any idea what I am doing wrong? I can't find anything online.

I also have the same problem. I think it is connected to #25

Can someone help us?

Thank you!!!
