Numpy error when loading package

[simonbyrne]

ERROR: LoadError: PyError (PyImport_ImportModule

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

PyCall is currently configured to use the Julia-specific Python distribution
installed by the Conda.jl package.  To install the vtk.util.numpy_support module, you can
use `pyimport_conda("vtk.util.numpy_support", PKG)`, where PKG is the Anaconda
package the contains the module vtk.util.numpy_support, or alternatively you can use the
Conda package directly (via `using Conda` followed by `Conda.add` etcetera).

Alternatively, if you want to use a different Python distribution on your
system, such as a system-wide Python (as opposed to the Julia-specific Python),
you can re-configure PyCall with that Python.   As explained in the PyCall
documentation, set ENV["PYTHON"] to the path/name of the python executable
you want to use, run Pkg.build("PyCall"), and re-launch Julia.

Something perhaps similar is described here: https://marc.info/?l=vtkusers&m=142478433909254

It seems that the default vtk Python package installation assumes that instead of "python" command one will use "vtkpython". So, there is a chance that either pointing PyCall to vtkpython instead of python (PYCALL_JL_RUNTIME_PYTHONHOME and PYTHON env vars) or setting PYTHONPATH and LD_LIBRARY_PATH to include location of the vtkCommonCorePython.so file will help.

Somehow I missed this issue. You seem to be using Python 3.7. I will try to simplify the setup process using PythonCall.jl #6.
