#21210 Installing detectron2 through pants New discussion created by johnathanchiu I am trying to install

detectron2

via

pants generate-lockfiles

. I've added the following line to my `requirements.txt`:

detectron2 @ git+<https://github.com/facebookresearch/detectron2.git@2a420edb307c9bdf640f036d3b196bed474b8593>

The error I get is
