Question about fine-tuning

[kimwin2]

Firstly, thank you for your great effort to make this project.

When will the fine-tuning code be released? If it's delayed, could you please let me know the learning rate used in the end-to-end training? I've tried to reimplement the fine-tuning using the model output logits, but while the train loss decreases, the evaluation loss keeps increasing.

Sorry, I've been too busy lately, and I'll need to delay the open-sourcing by a few more weeks. The VPTQ paper includes the learning rate —make sure to fine-tune it carefully, as I remembered it being quite sensitive. Additionally, the trainable parameters are RMSNorm, centroids, and the LM head. Remember to keep the embeddings frozen.

I guess your experiment is overfitting. Remember to increase the accumulation batch size.

Thank you for your kind reply.

I have loaded a packed model into my existing QAT pipeline, but I'm getting a multi-GPU error. It seems to be caused by the int16 precision. Should I train with a saved model instead of a packed one?

Yes, I encountered the same issue at the time. It seemed to be related to the data type handling in NCCL. My workaround was to save the unpacked model as a .pt file and use approaches like viewing the index as a float. This was also one of the reasons for the delay in releasing the fine-tuning code. Apologies for the inconvenience—this definitely needs to be addressed.
