Invalid training loss

[hshiah]

The training loss on brats2020 of new version is usually nan.

[hshiah]

When the loss is not NAN, the grad_norm is extremely large like 7.44e+04, while the previous version is usually around 10.
May I ask the reason? I train the model on raw brats2020 training data.

I fixed the bug, please update the project and try again.

Hi, I tried the newest version and the model is stuck at training stage. I checked the GPU memory usage and it keeps a small value (around 2500 MiB) instead of normal value.

@hshiah I checked it again, it works fine in my workplace. Did you run it on GPU? You may need to add --gpu 0.

I tried it again and it works. Sorry for my mistake. 获取Outlook for Android<https://aka.ms/AAb9ysg>
