What happened?

Errors when trying to use 4xUltrasharp_4xUltrasharpV10.pt and 4xNMKDSuperscale_4xNMKDSuperscale.pt.

Steps to reproduce the problem

1. Enter any prompt.
2. turn on upscaling.
3. select 4xUltrasharp_4xUltrasharpV10 or 4xNMKDSuperscale_4xNMKDSuperscale from the dropdown menu.
4. Press "Generate"
5. watch console output

What should have happened?

Scaler should have loaded and properly executed without error, as per previous versions (I was on 1.7.0 until recently).

RuntimeError: PytorchStreamReader failed reading zip archive: failed finding central directory

Corrupt download, delete and re-download is my best guess.

maybe you're right I assume that he's using the same known good file because he wrote

Scaler should have loaded and properly executed without error, as per previous versions (I was on 1.7.0 until recently).

I take this as fine 1.7 but in 1.8 when we switch to spandrel it stoped not working
not sure now

I'm sorry, I guess I wasn't 100% clear.

This was tested on not one, but two installs of 1.9.3, done days apart. Logs are taken from a minutes-old, fresh, clean install, which I did in order to satisfy the The issue exists on a clean installation of webui checkbox on my report. The two scaler files in question, 4xUltrasharp_4xUltrasharpV10.pt and 4xNMKDSuperscale_4xNMKDSuperscale.pt were copied directly from my 1.7.0 install, which is functioning correctly.

[EDIT] I do not know why it is even mentioning a zip file in the error log - the .pt files aren't zipped, unless there is something I do not understand about the .pt format?

I skipped from 1.7.0 to 1.9.3 - doing a fresh install, not an update. Then to get the information for this report, I did another fresh, clean install. Copied the previously working .pt files over from my 1.7.0 install.

Well, just working off the error message: If the .pt files are actually intact .pt files (i.e. zips) you should be able to rename them to e.g. 4xUltrasharp_4xUltrasharpV10.zip and open them with your favorite archiver. Alternately, if you're on an UNIX system, file 4xUltrasharp_4xUltrasharpV10.pt and/or zipinfo -l 4xUltrasharp_4xUltrasharpV10.pt should show you what they actually are.

It's possible our earlier architecture had been happy loading files with the wrong extension.

F I think I found the issue
try rename the .pt to .pth
btw I don't think 4xUltrasharp(ESRGAN) are zip files

[AlexysLovesLexxie]

Renaming the `,pt` files to `.pth` worked a treat. interestingly enough, renaming them to .zip and trying to open them was a no-go, even on re-download. but your fix actually fixed it. I will suggest to the uploaders of these files on CivitAI that they may want to update the file extension, unless you guys plan on changing the code so that they work as they used to? cheers!
