Cannot Install `octree_handler` on Google Colab

[xbais]

Hello. I am trying to run the code on Google Colab. While trying to install the third party dependency (following the instructions given in the Dockerfile) octree_handler via the command:

cd depoco/submodules/octree_handler && pip3 install -U .

...I get the following error:

Processing /content/git-clone/submodules/octree_handler
  DEPRECATION: A future pip version will change local packages to be built in-place without first copying to a temporary directory. We recommend you use --use-feature=in-tree-build to test your packages with this new behavior before it becomes the default.
   pip 21.3 will remove support for this functionality. You can find discussion regarding this at https://github.com/pypa/pip/issues/7555.

same issue...any solution now?

The issue is somewhere with pybind11-dev apt package getting installed in the Colab runtime.

Doing : !pip install "pybind11[global]" ...instead of : !sudo apt install pybind11-dev ...and then proceeding with the usual steps works for me....(for now).
