During repeated tests, I also observed significant variation in the loss values during the first iteration. Here are the loss values for reference: [2023-06-08 17:46:05,132][main][INFO] - [1]: total_loss=5423033104869406.0000 rot_loss=5423033104869354.0000 trans_loss=3.3963 bb_atom_loss=39.0931 dist_mat_loss=9.6093 examples_per_step=3.0000 res_length=291.0000, steps/sec=5.74526

However, regardless of the initial loss variation, the training process consistently encounters an error on the second iteration
Hi,
Regarding the NaNs with different GPUs, I don't know what's happening and can't offer help. I train with A6000 or A100 on my servers. It's likely something weird with CUDA. I would expect there to be significant variance of the loss on the first iteration. The batch sizes can be pretty small so you may get a bad batch on the first step. As long as training stabilizes it should be fine. What error are you running into on the second iteration? Is it the NaN so it's about the GPU device?
I found that during the first time the loss backpropagated, many .grad became Nan, but I don't know the specific reason yet.
Hi, we just posted a update that affects the rotation score learning. Please take a look at our README. I'm not sure if it's related to your problem but it might help.
@Z-MU-Z, I personally have not encountered an error like this while reproducing the results for this model. The issue might be related to your local CUDA version or (more specifically) your GPU. Are your local CUDA drivers up to date?
Closing due to inactivity.
I encountered an issue while using a specific GPU (NVIDIA GeForce RTX 4090) for training(However, when I use the same environment on 3090, the training process runs smoothly without any errors). During the training process, I received the following error message:
