Importing Statsmodels API

[Sinansi]

It is always headache to import statsmodels.

I have the statmodels installed in the target environment but PyCall insist that is not there.

julia> sm = PyCall.pyimport("statsmodels.api")
ERROR: PyError (PyImport_ImportModule

The Python package statsmodels.api could not be imported by pyimport. Usually this means
that you did not install statsmodels.api in the Python version being used by PyCall.

PyCall is currently configured to use the Python version at:

C:\Users\sinan\anaconda3\envs\py38\python.exe

and you should use whatever mechanism you usually use (apt-get, pip, conda,
etcetera) to install the Python package containing the statsmodels.api module.

One alternative is to re-configure PyCall to use a different Python
version on your system: set ENV["PYTHON"] to the path/name of the python
executable you want to use, run Pkg.build("PyCall"), and re-launch Julia.

Another alternative is to configure PyCall to use a Julia-specific Python
distribution via the Conda.jl package (which installs a private Anaconda
Python distribution), which has the advantage that packages can be installed
and kept up-to-date via Julia. As explained in the PyCall documentation,
set ENV["PYTHON"]="", run Pkg.build("PyCall"), and re-launch Julia. Then,
To install the statsmodels.api module, you can use pyimport_conda("statsmodels.api", PKG),
where PKG is the Anaconda package the contains the module statsmodels.api,
or alternatively you can use the Conda package directly (via
using Conda followed by Conda.add etcetera).

The problem was solved by the following lines:

ENV["PYTHON"] = ""
Pkg.build("PyCall")

I was using an Anaconda Conda environment, but now switched to Julia Conda environment.
Not sure how that solved it. Perhaps, Conda.jl is more compatible with Julia than Anaconda Conda.
