Cannot install Pytorch #17

Open lacan opened 6 months ago

lacan commented 6 months ago

This is related to the same issue as https://github.com/qupath/qupath-extension-wsinfer/issues/54

On a Win11 machine, with QuPath 0.5.0 I cannot install pytorch due to a java.nio.file.AccessDeniedException

I tried running QuPath as a standard user or as an administrator, with no success...

Sorry Oli, missed this issue when you reported it. I can't reproduce on Win10 nor Win11, and my only suggestions would've been to try changing the permissions on the folder, try elevated permissions, or try a different folder.
