I have installed the package python-numpy on Ubuntu 16.04 LTS. Unfortunately, the package is broken:

>>> import numpy
Traceback (most recent call last):
 File "<stdin>", line 1, in <module>
 File "/usr/lib/python2.7/dist-packages/numpy/__init__.py", line 180, in <module>
 from . import add_newdocs
 File "/usr/lib/python2.7/dist-packages/numpy/add_newdocs.py", line 13, in <module>
 from numpy.lib import add_newdoc
 File "/usr/lib/python2.7/dist-packages/numpy/lib/__init__.py", line 8, in <module>
 from .type_check import *
 File "/usr/lib/python2.7/dist-packages/numpy/lib/type_check.py", line 11, in <module>
 import numpy.core.numeric as _nx
 File "/usr/lib/python2.7/dist-packages/numpy/core/__init__.py", line 14, in <module>
 from . import multiarray
 ImportError: cannot import name multiarray

Does Python often get broken in Ubuntu? Numpy is a pretty basic package.

    Is your system up-to-date? I have no problem with numpy. What is your python and numpy version? – salman Jun 23 '16 at 13:19

    Sorry for message. I found the problem. I was using the wrong python since I had installed anaconda. Removing anaconda make the system works – Mathieu Dutour Sikiric Jun 23 '16 at 13:30

    @MathieuDutourSikiric You should write an answer to let others on the site know how you solved your problem. And no, it is not frequent to have `numpy` broken on Ubuntu if you knew how to install it. – edwinksl Jun 23 '16 at 19:11
  • I had a similar problem, simply because my LD_LIBRARY_PATH included a directory with an incompatible Openblas – xiawi Aug 25 '16 at 07:49

    VTR because this is yet another example of the perils of using Anaconda in Ubuntu. – karel Feb 24 '18 at 07:23

  • OP solved the problem:

    ...I found the problem. I was using the wrong python since I had installed anaconda. Removing anaconda make the system works

  • An alternative way without uninstalling Anaconda, reset python link to default (pointing to python2 from repository)

    $ ls -l /usr/bin/python
lrwxrwxrwx 1 root root 9 Dec 10  2015 /usr/bin/python -> python2.7

  • Thank you for adding the answer. I don't know why they close this question. – aerin Feb 23 '18 at 22:47
  • @ToussaintLouverture , I was one of close voters my reasons: from new user who didn't submit a answer but just mention a work around in comment without any further collaboration, no up-votes on question (but it was new anyway). Now I would change my mind as reason are not valid anymore: it get some interest from other users and also xiawi mention another option with better fit as answer. I'll as for reopening. Thank you. – user.dz Feb 24 '18 at 07:01
