Issue

I am trying to add Detectron2 (https://detectron2.readthedocs.io/en/latest/) to my project. I am using a very recent version of pytorch for other reasons, so I first installed a nightly build of torch/torchvision (see pyproject.toml), and am now trying to add detectron2 from this pull request facebookresearch/detectron2#4868 :

poetry -vvv add git+https://github.com/johnnynunez/detectron2.git

I am getting the following output: https://gist.github.com/ldorigo/4bcc4b270cf24afbab3f9d20810c82a8

I am not sure whether this is an issue with Poetry or the upstream package, if so let me know and I will open an issue there.

it's a detectron packaging problem, as you can verify with pip install --use-pep517 <package-name>

please close

[dimbleby]

also duplicate #3712, so please close it twice!

[ldorigo]

Sorry I missed that issue. Since apparently upstream Detectron2 facebookresearch/detectron2#4234 does not want to fix the issue, is there anything that can be done to include detectron2 in a poetry project?

[dimbleby]

no

[radoering]

You can build wheels (with other means than poetry) and add them. (You probably need one wheel for each platform and python version you want to support.)
