Pytorchstreamreader failed reading zip archive: failed finding central directory

Error while using CPU for segmentation- "NET ERROR: PytorchStreamReader failed reading zip archive: failed finding central directory"

closed

When I try segmentation using CPU, I am getting the error- "NET ERROR: PytorchStreamReader failed reading zip archive: failed finding central directory" I can't check if it works using GPU because my graphics card compute capacity seems to be incompatible with pytorch

Windows 10 OS, and NVIDIA GEforce GT730

can you try deleting your models folder and redownloading them? there may have been an interruption during download (see this issue: //github.com/pytorch/pytorch/issues/31620)?

the models folder is in your home directory /.cellpose/models, in windows e.g. C:/Users/carsen/.cellpose or linux e.g. /home/carsen/.cellpose

going to close issue for now please comment if it's still not working

Hey everyone... I've been really looking forward to trying out DiscoDiffusion for quite some time now. I finally sat down to give it a go but I'm getting some error messages and am not sure how to fix it. Any one have an idea what these errors refer to and how I can remedy them?

Question:

I’m trying to run Disco Diffusion v5 with basically default settings and getting this error when I try to create the image. Does anyone know how to fix this?

Starting Run: Horse 02(0) at frame 0 Prepping model...

Answer:

My way to solve this problem is to delete folder ‘AI’ in google Drive and run it all again. I guess the problem may be caused by an incomplete pre-traning model that was not downloaded correctly by the first run, which prevents the correct version of the model from being downloaded.

If you have better answer, please add a comment about this, thank you!

Pytoch reports an error:

PytorchStreamReader failed reading zip archive: failed finding central directory

Error reporting position

An error is reported if the pre training model is not downloaded

resnet101 = torchvision.models.resnet101(pretrained=True)

Solution:

Delete the file C:\Users\Username/.cache\torch\hub\checkpoints.pth
