numpy/core/multiarray.so: undefined symbol: _Py_ZeroStruct

I'm new to both Linux and Python. I'm working on a Ubuntu 16.04.

My original Python is

python --version Python 2.7.8

I'm trying to import numpy into python3. However, when I try to import numpy I get this error

Traceback (most recent call last):

File "/usr/local/lib/python2.7/dist-packages/numpy/core/init.py", line 16, in from . import multiarray ImportError: /usr/local/lib/python2.7/dist-packages/numpy/core/multiarray.so: undefined symbol: _Py_ZeroStruct

During handling of the above exception, another exception occurred:

Traceback (most recent call last): File "", line 1, in File "/usr/local/lib/python2.7/dist-packages/numpy/init.py", line 142, in from . import add_newdocs File "/usr/local/lib/python2.7/dist-packages/numpy/add_newdocs.py", line 13, in from numpy.lib import add_newdoc File "/usr/local/lib/python2.7/dist-packages/numpy/lib/init.py", line 8, in from .type_check import * File "/usr/local/lib/python2.7/dist-packages/numpy/lib/type_check.py", line 11, in import numpy.core.numeric as _nx File "/usr/local/lib/python2.7/dist-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:

/usr/local/lib/python2.7/dist-packages/numpy/core/multiarray.so: undefined symbol: _Py_ZeroStruct"

The python I'm using to import numpy is Python 3.5.2 and it seems to be trying to use the package in Python 2.7.

I've tried :

sudo apt-get update
sudo apt-get install python3-pip
sudo apt-get install python3-numpy

and also :

sudo python3 -m pip uninstall pip && sudo apt install python3-pip --reinstall 
sudo apt install python3-numpy python3-scipy

It seems a similar problem to what others have faced but none of the solutions seem to work?

You installed pip for both python2.7 and python3. To use pip of python3 just you need to use pip3 instead of pip.

pip3 install package
