Versions: OS Ubuntu 18.04.6 LTS, Blender 2.92, Default Python version of machine 3.7.6 Anaconda, Blender's python interpreter 3.7.7, BlenderGIS 2.2.8/2.2.5
First of all I want to install an add-ons in Blender, the so called "BlenderGIS".
Like many users before me I'm exposed to the issue of numpy package:
Traceback (most recent call last):
File "/usr/lib/python3/dist-packages/numpy/core/__init__.py", line 16, in
from . import multiarray
ImportError: cannot import name 'multiarray' from 'numpy.core' (usr/lib/python3/dist-packages/numpy/core/__init__.py)
During handling of the above exception, another exception occurred:
Traceback (most recent call last):
File "/usr/share/blender/2.92/scripts/modules/addon_utils.py", line 351, in enable
mod = import(module_name)
#... and so on...
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: cannot import name 'multiarray'
I tested 2 main approaches:
- While numpy was clearly installed, I unistalled it
pip uninstall numpyand installed again the 1.19.3 version as adviced by Dope and otherspip install numpy==1.19.3. Evenpython3.7 -m pip install numpy imageioas shown by eudoxos - To try different versions of BlenderGIS: 2.2.5 (numpy import issue), 2.2.7 (not adapted to my blender version that is too old), 2.2.8 (numpy import issue).
Both did not work.
Now I remarked something in the blender's python console. The version used is not the same as my default python interpreter:
Default python in my machine:
(base) avy@machine:~$ python
Python 3.7.6 (default, Jan 8 2020, 19:59:22)
[GCC 7.3.0] :: Anaconda, Inc. on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import numpy
>>> #no problem
Blender's python interpreter:

numpy is clearly present in /usr/lib/python3/dist-packages. Making a search of "multi" in the /usr/lib/python3/dist-packages/numpy folder gives those few files: [Name | Place]
- multiarray.cpython-36m-x86_64-linux-gnu.so | core
- multiarray_tests.cpython-36m-x86_64-linux-gnu.so |core
- test_multiarray.py | core/tests
- test_multiarray.py | matrixlib/tests
- test_multiarray.cpython-36.pyc | core/tests/pycache
- test_multiarray.cpython-36.pyc | matrixlib/tests/pycache
- multiarray_api.txt | core/include/numpy
- __multiarray_api.h | core/include/numpy
This is not very clear for me why blender use a different python interpreter and moreover the absence of clear possibilty to change it maybe because modules like bpy, bpy.data and so on are very specific to blender
The last thing I did not try is the PYTHONPATH because I prefer advices on it instead of making more mess as told by sardathrion "However, do not mess with PYTHONPATH. More often than not, you are doing it wrong and it will only bring you trouble in the long run. For example, virtual environments could do strange things… "
