I mentioned in my original question that I have tried Python 3.6.2 and that it indeed had no problems with numpy but that it on the other hand gave rize to another problem, namely failing installation of vtk (pip says 'Couldn't find a version that satisfies the requirement vtk'.

The short answer is you need to upgrade Python, not numpy. For the long answer please see https://stackoverflow.com/questions/44537131/numpy-library-importerror-dll-load-failed-the-specified-procedure-could-not-be which in turn refers to https://bugs.python.org/issue29943.

Apparently, the module "multiarry" is implemented in a separate DLL (= "Dynamically Loaded Library") and loading this DLL failed. There can be several reasons for such a failure, among others: * the DLL is missing * the DLL is corrupted * the DLL depends on something which is missing or corrupted * there is a version mismatch (e.g. between the DLL and the Python trying to load it) An initial step could be to try to reinstall "numpy" and see whether the problem goes away. -- https://mail.python.org/mailman/listinfo/python-list
numpy not working any more
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? Poul Riis Traceback (most recent call last): File "C:\Users\pr\AppData\Local\Programs\Python\Python36\lib\site-packages\numpy\core\__init__.py", line 16, in from . import multiarray ImportError: DLL load failed: Den angivne procedure blev ikke fundet. During handling of the above exception, another exception occurred: Traceback (most recent call last): File "C:/pr/python/numpy_test.py", line 1, in import numpy as np File "C:\Users\pr\AppData\Local\Programs\Python\Python36\lib\site-packages\numpy\__init__.py", line 142, in from . import add_newdocs File "C:\Users\pr\AppData\Local\Programs\Python\Python36\lib\site-packages\numpy\add_newdocs.py", line 13, in from numpy.lib import add_newdoc File "C:\Users\pr\AppData\Local\Programs\Python\Python36\lib\site-packages\numpy\lib\__init__.py", line 8, in from .type_check import * File "C:\Users\pr\AppData\Local\Programs\Python\Python36\lib\site-packages\numpy\lib\type_check.py", line 11, in import numpy.core.numeric as _nx File "C:\Users\pr\AppData\Local\Programs\Python\Python36\lib\site-packages\numpy\core\__init__.py", line 26, in 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. -- https://mail.python.org/mailman/listinfo/python-list
