Error installing with pip - ERROR: No matching distribution found for torchvision==0.8.2

After doing pip install --upgrade git+https://github.com/rbrtwlz/fastai_object_detection
ERROR: No matching distribution found for torchvision==0.8.2

I already have torchvision 0.10 installed, does this absolutely require 0.8.2? It wants older fastai too (current ver. is 2.5.2).

Is there a way to install this without downgrading?

Ok, I created new empty environment and manually installed everything from setup.py. Everything install except
mean_average_precision @ git+https://github.com/bes-dev/mean_average_precision

It doesnt work (package not found error). I then tried pip install your package (the only thing I was missing was mean_average_precision ) and of course your repo fails installing it as well

Hi roboserg,

currently there is a error with fastai's type dispatch when using torch > 1.7.1, so torchvision==8.2 is required. I recommend using a virtual environment.

And mean_average_precision is just required for testing now, by default it uses my port of it (from numpy to pytorch).

But your error is regarding to the installation of pycocotools. I never tested it on windows, but according to this issue you could try to install pycocotools-windows.

Btw, if you don't want to create a dataset with CocoData class, then you don't need pycocotools.
