The program hangs on `Setting up PyTorch plugin "filtered_lrelu_plugin"... `

[ll2pakll]

Hello, I had everything working fine, but at some point, I interrupted the program without letting it finish. And now I'm facing the fact that the program hangs on Setting up PyTorch plugin "filtered_lrelu_plugin"... and nothing else happens. This happens both when trying to generate new images with gen_images.py and when trying to open the visualizer. In this case, visualizer opens but hangs with Loading and then the name of the network file. First I reinstalled torch and all related packages, then I replaced all the stylegan3 files with the ones downloaded from the repository. This didn't help. So I completely deleted the virtual environment and re-created it by downloading and installing all the required modules. But the behavior has not changed. I have no idea what to do.

I had to reinstall Windows completely to make it work again

Same issue here, solved by clearing the torch extension cache inside windows user folder \AppData\Local\torch_extensions\torch_extensions\Cache solution found in #48 (I didn't do the first step of installing gcc, just clearing the cache worked)

also, for macos the directory might be /home/jack/.cache/torch_extensions according to #114

In my experience I've had this happen several times and realized it was caused by closing the command prompt window while the bias_act_plugin or upfirdn2d_plugin was loading. Then the next time you're starting up a training session it will hang. So it seems that the plugins cache folder becomes corrupted and needs to be flushed. As mentioned above, this can be achieve by doing the following:

• Completely remove: $HOME/.cache/torch_extensions (Linux) or C:\Users\<username>\AppData\Local\torch_extensions\torch_extensions\Cache (Windows) and re-run StyleGAN3 python code.

Thanks, removing the .cache directory has worked for me.

Removing .cache worked for me as well.
