How to install a non-pip and non-conda pacakge

Currently I use the environment.yml file to install the packages needed for this challenge via conda.

Now I would like to use an additional package developed by others on github where they only made it installable via cloning the repo and do pip install . and I am not sure how to actually do this.

I read in the repo2docker link provided by you (https://repo2docker.readthedocs.io/en/latest/config_files.html#setup-py-install-python-packages) that it is possible to include a setup.py file but it sounded like this is to install the repo I push instead of installing someone else’s code.

In summary: I would like to use a bunch of conda installed packages as well as one package that I need to install from source in my own code. How should I do that?

Thank you for your help.
