Hi @basernapairs , I believe this problem is related to where PyCall is looking for our python packages. PyCall defaults to a python build that comes in Conda.jl. Following the docs on PyCall I was able to set up a new environment, install openfermion, point my PyCall build to that envs python, and then successfully import OpenFermion.

I used the following after making a new env with a fresh OpenFermion build.

julia> ENV["PYTHON"]="<path to your python3.x"
pkg> add PyCall  # or Pkg.build("PyCall") if you have it already

Then close your julia console. Reopen and try importing OpenFermion. I was able to see the modules from inside the Julia console so I assume they are usable.
