import of pyarrow fails #373

Open hhaensel opened 9 months ago

hhaensel commented 9 months ago

I observe a very strange behaviour that pyimport fails on windows if it was installed via conda-forge. If it was installed via pip, everything works fine.

I've opened an issue on conda-forge pyarrow, but maybe someone here has an idea...

MWE:

julia> ENV["JULIA_PYTHONCALL_EXE"] = "C:\\ProgramData\\mambaforge\\envs\\pyarrow_conda\\python.exe"
"C:\\ProgramData\\mambaforge\\envs\\pyarrow_conda\\python.exe"

julia> using PythonCall

julia> pyimport("pyarrow")
