RuntimeError: Input type (torch.cuda.HalfTensor) and weight type (torch.FloatTensor) should be the same
See original GitHub issueIssue Description
Tried running a training session following the example on the site but I keep getting this error.
Tried launching webui with --no-half option but does not change anything.
Any idea?

This happens for me if I select ‘Train with reconstruction’, it also seems to break regular textual inversion permanently though I only noticed that once and haven’t tried again.
To fix it, I had to:
Replace /modules/ui.py with the original, since this extension makes minor changes to the file and then it can’t work anymore without the extension present, which is a big problem.
Remove the DreamArtist folder from /extensions/ (not just disable it).
Start the web-ui.
Then with the ui running, redownload or move the DreamArtist folder back into extensions.
Then with the ui still open, use the refresh button in the extensions tab.
Ensure the extension is checked to be enabled
Close and restart the web-ui completely
It should work again, and make sure to not click ‘Train with reconstruction’
If you just want to remove the extension permanently, you just need to do 1 & 2.
It’s either that or remove --no-half --precision full from the commands, it works at 512x512 with those removed again.
