It looks as though the assets haven't installed properly. Can you close the plugin window, restart Unreal, reopen the plugin window and try to reinstall the dependencies then restart Unreal again?

Oct 31 '22 07:10 Mystfit

Ok, I just ran into the error from the first part. At the moment the UI will throw that error when the plugin is visible when opening Unreal. Closing the plugin window and reopening it should fix that issue.

Now it just says "collecting torch" while my computer freezes

Nov 01 '22 03:11 ltsfwrs

What happens if you leave it for around 15 minutes?

Nov 01 '22 09:11 Mystfit

@ltsfwrs Did you manage to install torch int he end?

Nov 03 '22 06:11 Mystfit

No, it just keeps getting stuck after a certain point.

Can you try installing the latest version of the plugin? It will get rid of the first batch of errors and try and update your torch to the latest version.

I'm going to try and finally fix this error tomorrow. It should go away if you reload the plugin window but I think the earlier error about torch not finding caffe2_nvrtc.dll is the culprit here which then causes the other libraries to not get loaded later on like the huggingface_hub module. Since torch is the culprit here I will have to examine what that dll actually links against to try and figure out if you are missing some sort of dependency. I'm hoping that the upstream torch hasn't gone and uploaded a broken package. I'm thinking about adding a button to recursively remove all installed packages so we can force a full dependency reinstallation and see if that solves the problem.

Nov 11 '22 09:11 Mystfit

@gschian0 Just checking in on this issue. If you pull one of the latest plugin versions does it fix the caffe.dll error?

Nov 29 '22 22:11 Mystfit

Closing this issue as the dependency installer process has been updated since this issue.
