Detectron2 for Windows?

[felixgeen]

I cannot get Detectron2 to install, presumably because I am using Windows? Will there be a future update where there is an alternative tool that works with Windows? Would be very cool!

Detectron2 is not installed. Press enter to install it.

ModuleNotFoundError: No module named 'torch'

Indicates that you can likely fix this by installing pytorch first

I installed pytorch with conda install -c conda-forge pytorch and ran the script again with --mask_categories person car but it errored out somewhere near the end of the process. Is this something to do with the detectron2?

It seems like this error is unrelated to the Detectron2 command since I now get this error if I run --mask_categories or not. Could his be because I installed pytorch and broke something else in the process?

Colmap fails now on every dataset. Is there a potential fix?

Hi, how do you use detectron2 in instant-ngp? What is the command? Thx
