Thanks, this appears to be a very useful package which would solve many compatibility problems between windows, linux etc.

One thing I am wondering is how to import a local module. In PyCall this would be done as:

const pymodule = PyNULL()
pushfirst!(PyVector(pyimport("sys")["path"]), (@__DIR__)*"/dir_relative_to_src") 
copy!(pymodule, pyimport("mylocalmodule"))

Help on how to do this in PythonCall would be highly appreciated!

    Glad you like it!

    The equivalent in PythonCall is:

    const pymodule = PythonCall.pynew()
pyimport("sys").path.append("some/path")
PythonCall.pycopy!(pymodule, pyimport("mylocalmodule"))

    Thanks, that works! See https://github.com/JuliaGeodynamics/geomIO. Next up is figuring out why CI fails on windows, but works on Mac/Linux.

    I'm following this pattern and getting occasional segfaults when I try to access the imported module (the one that I pycopy!ed). Do I need to do something like GC protect that pointer so it doesn't get GCed? Can I even do that on the julia side or do I need to do it on the python side somehow?

    I get the same behavior FWIW when using Ref{Py} to store the imported module as well...

    Wow and when I pyimport the module afresh each time before referring to it. I suspect this may be something specific to my module and how I'm using it!
