Hi! Thanks for the great work! I encountered an issue during the pretraining stage. I was fine-tuning the vision tower, the linear adapter, and the Large Language Model (LLM) in the pretraining stage. The loss decreased to around 0.7X at 0.02, but it suddenly spiked to over 20. After some time, it gradually decreased to around 6.x. Is this normal? And why did this happen?

It is so wired. Could you provide your training script? Have you modified any training code?

Sure,I just follow the LLaVa1.5.

And I note that the learning rate and batch size are not the same as yours. I will fix that and tell you later. My modifications to the training code did not influence the results with the llava dataset.

I found you close this issue. Did you solve it?

I changed the learning rate from 1e-3 to 2e-5, which is same as yours, and trained the vision encoder in the last half of the architecture during the pre-training stage. Finally, the loss continued to decrease to the 0.2x range.
However, I can't explain this issue, and ultimately, my results are not better than those from LLaVA1.5 based on your dataset and using the LLaVA1.5 code. Perhaps there are some other aspects that I haven't considered.
