ERROR: InitError: PyError (PyImport_ImportModule

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

PyCall is currently configured to use the Python version at:

/usr/bin/python3

and you should use whatever mechanism you usually use (apt-get, pip, conda,
etcetera) to install the Python package containing the scipy 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 scipy module, you can use `pyimport_conda("scipy", PKG)`,
where PKG is the Anaconda package that contains the module scipy,
or alternatively you can use the Conda package directly (via
`using Conda` followed by `Conda.add` etcetera).
