Issue: RuntimeError: PytorchStreamReader failed reading zip archive: failed finding central directory --- What zip archive are we talking about ?
Labels: bug-report

Hello everyone,

I'm trying to lauch stable-diffusion-webui from few days, but impossible.
I'm a newbie, I am on windows 10.
I dowloaded model, stable-diffusion, python 3, git.
There were some bugs until the one which bring me here to ask for help.



_**To correct first bugs** I had to add to the "webui-user" (batch) in the line set_ **COMMANDLINE_ARGS= "--skip-torch-cuda-test --disable-safe-unpickle --lowvram**" 👍 


### And now I arrived to the point where there is :

I tried to re-download stable-diffusion, python 3, put codeformer.pth in models/codeformer (all this "solutions" were find on internet), but nothing.
I checked on this site, on reddit and some others websites to get any solutions, nothing.



RuntimeError: PytorchStreamReader failed reading zip archive: failed finding central directory :
**which zip archive and where are we talking about ?**

**Do you have any general idea for this issue please ?**


_**The idea of someone experienced, even trivial, may be the right one, I will try the proposed solutions.**_


_Thanks by advance for your time and your expertise !_
