I have been trying to load Animation Nodes, but can't seem to get Numpy to work, and have no idea how to install. I have done a clean install on latest version (and other tower works fine) but this particular machine won't work. I have not had to install Numpy on the working machine. The Numpy folder has been installed, I even copied it to the Modules folder, and it still won't work.

I really need to use these nodes.

When I try import I get: 

Traceback (most recent call last):
  File "<blender_console>", line 1, in <module>
  File "C:\Program Files\Blender Foundation\Blender\2.78\scripts\modules\numpy\__init__.py", line 180, in <module>

  • $\begingroup$ I think this relates to library loading on your system. See if this answer provides enough info to resolve the issue. I'm not sure of the equivalent in windows. $\endgroup$ Commented Sep 21, 2017 at 4:14

Blender installation issue

Blender comes with numpy installed. Maybe something got wrong in your blender installation, if so you should not be able to import numpy directly from the python console: (deactivate AN first)

Numpy Test

If these simple commands do work, this means AN is the problem and you should create an issue thread on the github repo or contact Jacques Luke directly. If they don't work, it means Blender wasn't installed correctly, and you should try:

  • to copy directly the site-packages folder at %version%\python\lib\site-packages directory. (Download the blender zip and copy the directory).
  • As I have not tried it myself, maybe the last method will create conflicts, so if it doesn't work, make a new installation of blender.

"pip install --user --upgrade numpy" run this in cmd

  • $\begingroup$ Blender uses a bundled python install not on the system path, and should already include numpy. I don't think this will work as it stands. $\endgroup$ Commented Jan 6, 2019 at 23:05
