no datalad/packages - using python venv on RHEL

[samanthareisman]

I am using a remote Linux desktop (RHEL) and my organization's documentation requires that we use python venv to install python packages. I am trying to install datalad & git-annex and running into many issues. I have tried to install git-annex a number of ways, including using the datalad-installer (which is where I run into the above issue). I can pip install datalad and pip install datalad-installer successfully, but this does not install a datalad/packages dir. I cannot install git-annex using sudo apt get because this is a shared cluster, and I don't have sudo permissions. When I did this in a conda env, I was able to successfully install everything using the relevant conda commands on the same Linux. Unfortunately, I can no longer use conda and have to make the switch to the python venv.
