ValueError: matrix contains invalid numeric entries

[1653042420]

Hi! Thanks for sharing your excellent work! when I trained the Lidar branch
I only have one RTX 4080，and my batch size is 4. I encountered this issue when using the previously released code to train the LiDAR branch.Now,I know that it was caused by an incorrect learning rate. I want to konw if I use the latest released code, do I still need to adjust the learning rate based on the total batch size？

I have the same problem. Do you have any new progress?

I have the same problem, too. And when I increase the max_epoch, the corresponding lr needs to be smaller. I have to adjust the lr again and again.

Hi, I have adjusted also the learning rate but in the 5th epoch it starts to slow down a lot. If you have made any modification in the lr schedule, can you show it? As my batch_size if 3 (approx 1/10 of the original) I have changed lr (from optimizer and min_lr_ratio) to 1/10 of original. Before this change my training was stucked at epoch2 and now it reaches epoch5, but as said, it starts to go too slow.

Thanks in advance
