OCR does nothing, it seems

[Juiin]

I tried to build the new OCR Support Version, it seems to have build correctly. But when i try to scan something an empty Search Window appears to the right and thats it. I assume this feature is for scanning Image-based subtitle files like .sup, but i also tried to scan Characters in the actual Video. Since i am not sure about what is supposed to happen, i can't exactly tell what is not working.

I'm on Windows 10

Launch memento_debug.exe and post the output.

Surprisingly, it seems to work fine with memento_debug.exe The ocr scans correctly now and a dictionary entry is shown. Still the same issue with memento.exe though.

Bizzare. The only difference between the two versions is the one that doesn't work uses WinMain. The fact that a search opens when OCR is triggered means it returns something. I'll have to try to reproduce it later. Due to the holidays I won't have access to a computer running Windows for about a week. Sorry I can't get to this sooner.

I'm going to need your help. I tested OCR on Windows as far as being certain it would work if you managed to get manga-ocr installed. I wasn't able to actually get manga-ocr installed since I couldn't get pytorch to install via pip. Can you give me instructions on what you did to get it working on Windows?

[Juiin]

Hmm, it has been a while so i don't remember exactly what i did. But i remember already having had installed Manga-ocr through https://github.com/kha-white/mokuro this, so i didn't need to install it again for Memento.

I don't remember having any problems with pytorch, but i'm not 100% sure. Sorry, that i can't be of more help.

[ripose-jp]

No problem. I might have to wait until PyTorch supports Python 3.10 on Windows before I can fix this though.
