Hi, I'm the author of PyTorch Metric Learning. I wandered in here after I noticed this repo in my dependencies list.
Not sure if this is the cause, but FYI if you have pytorch-metric-learning >= v0.9.90 and pytorch < 1.6.0, the loss will be NaN. This is due to a bug in pytorch that was only fixed in 1.6.0. So if you can't use pytorch 1.6.0, you should use pytorch-metric-learning <= v0.9.89.

Hi, Kevin. Thanks for your kindness and a great package!
Since I use Pytorch ==1.5.0, I downgrade pytorch-metric-learning to v.0.9.89 and it works well.
Thanks for your help!

Great to hear, that you managed to start training now. Just to make sure. You are using the most recent version from github?
What exact command did you use? I try to reproduce the error then.
Further, the most valuable information from the error is cut. I just see that train.py
throws an error. I assume that the loss is overloading for a reason.
You can try this command, to see if something happens to the metric loss:
python train.py dataset=ntu_swap_axis loss=only_classifier
You could also check if the error happens with one of the other datasets , looks like you are using the NTU 120 one shot experiments. E.g. with the Simitate experiment as described here.

Yes, I downloaded the newest version from GitHub.
I created env with requirements.txt and cudatoolkit==10.1.
I tried python train.py dataset=ntu_swap_axis
and encountered the error.
I tried python train.py dataset=ntu_swap_axis loss=only_classifier
with one epoch and it works well. (total_loss is calculated.)

@KevinMusgrave, first thanks for actively joining this issue. I will missuse the issue to also thank you for the great pytorch-metric-learning
library, which I think is a great contribution towards more reproducible and comparable metric learning approaches. I also recently read your "A metric learning reality check" paper [1] which pointed me out to a great set of hyperparameters and flaws in the training and evaluation strategy of the first preprint. I tried my best to follow your suggestions where applicable to which an updated preprint will follow.
