For some time I have been using python 3.6.0 on a windows computer.
Suddenly, my numpy does not work any more.
This one-liner program:
import numpy as np
results in the long error message below.
In an effort to solve the problem I tried to install python 3.6.2 followed by
all the modules I need. Here, there was no problem with numpy but then another
problem appeared: Installing mayavi apparently needs vtk but pip couldn't find
an acceptable vtk version.
What is the easiest way to make things work again?

raise ImportError(msg)
ImportError:
Importing the multiarray numpy extension module failed. Most
likely you are trying to import a failed build of numpy.
If you're working with a numpy git repo, try `git clean -xdf` (removes all
files not under version control). Otherwise reinstall numpy.
Original error was: DLL load failed: Den angivne procedure blev ikke fundet.
