numpy / core / multiarray.so：未定义符号：_Py_ZeroStruct

Question

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?

Answer 1

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
