pip install detectron2_densepose-0.6-py3-none-any.whl failed

[waaaok]

my python==3.11.9
i placed detectron2-0.6-cp311-cp311-win_amd64.whl and detectron2_densepose-0.6-py3-none-any.whl to ./ComfyUI/python/Lib/site-packages/
pip install detectron2-0.6-cp311-cp311-win_amd64.whl successfully installed
pip install detectron2_densepose-0.6-py3-none-any.whl failed

@waaaok facing the same issue, have you solved it?

[SohmP]

anyone got the solution ??

Here is the solution:

The error occurs because the build process for detectron2 can't find PyTorch (torch) in its isolated environment, even though it's installed in your virtual environment. This is due to pip's default behavior of using build isolation, which creates a temporary environment without your installed packages. Here's how to fix it:

Ensure Torch is Installed: Verify that PyTorch is installed in your activated virtual environment:

pip show torch

Install detectron2 with Build Isolation Disabled: Use the --no-build-isolation flag to allow the build process to access your installed packages:

pip install git+https://github.com/facebookresearch/[email protected] --no-build-isolation

Same for:

git+https://github.com/facebookresearch/[email protected]#subdirectory=projects/DensePose

You also need to patch the detectron2 because pillow changed some things.

Modify the detectron2 source code to use BILINEAR instead of LINEAR:

Open the file:

/path/to/venv/lib/python3.12/site-packages/detectron2/data/transforms/transform.py

Replace Image.LINEAR with Image.BILINEAR (line 46).

Save and restart ComfyUI.
