Error importing numpy after update

Hi guys, i just updated numpy (from 1.12 to 1.13) but it throws this error when i try to import it:

>>> import numpy
Traceback (most recent call last):
  File "/usr/lib/python3.6/site-packages/numpy/core/__init__.py", line 16, in <module>
    from . import multiarray
ImportError: /usr/lib/python3.6/site-packages/numpy/core/multiarray.cpython-36m-x86_64-linux-gnu.so: undefined symbol: PySlice_AdjustIndices

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/lib/python3.6/site-packages/numpy/__init__.py", line 142, in <module>

    from numpy.lib import add_newdoc

    import numpy.core.numeric as _nx
  File "/usr/lib/python3.6/site-packages/numpy/core/__init__.py", line 26, in <module>
    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: /usr/lib/python3.6/site-packages/numpy/core/multiarray.cpython-36m-x86_64-linux-gnu.so: undefined symbol: PySlice_AdjustIndices

PD: I am using Python 3.6.0

How can i solve it?

Wow, a different error than I was expecting.

Why are you on 3.6.0? Remember, partial updates are NOT supported!

Re: Error importing numpy after update

Hi, thank you for answer.

I am working with Python 3.6.0 because Python 3.6.1 it's giving me a lot of trouble, it just dies (throws "core generated" and other erros i can't remember right now) so i had to downgrade it.

Re: Error importing numpy after update

The best advice would be to seek help fixing the real problem then.

Less good but still sound advice would be to downgrade numpy to a version that is suitable for 3.6.0 which would be 1.12 ... so it's really no surpises that updating from 1.12 to 1.13 led to problems.
