[Bug]: upscaler for batch processing doesn't work

tralala87 commented 1 year ago

What happened?

Upscaling from a batch in extras doesn't seem to work. Neither from a directory.

Colab cell output

It is because the image you try to upscale don't have any png infos and so can't grab any parameters using stealth_pnginfo.py. It still seems to upscale it though.

Thank you for your answer! Will try with png type of format later in the day :))

Anonimouche commented 1 year ago

It's not the format in itself, when you create an image using the webUI it will inserts data in the image itself after creating it. For example here's the png infos on one of my generated image: https://i.postimg.cc/sgHXtc6B/pnginfos.png The image you were using had probably none of those which made retrieving any parameters impossible and sent an error.
