Question

I’m tired to import cv and numpy and get errors. I started importing cv and I got this error:

ImportError: numpy.core.multiarray failed to import
Traceback (most recent call last):
File “”, line 1, in <module>
File “/usr/lib/pymodules/python2.7/cv.py”, line 1, in <module>
from cv2.cv import *
ImportError: numpy.core.multiarray failed to import

So I installed numpy on Ubuntu using:

apt-get install python-numpy

So when I import numpy I get:

Traceback (most recent call last):
File “”, line 1, in <module>
File “numpy/init.py”, line 127, in <module>
raise ImportError(msg)
ImportError: Error importing numpy: you should not try to import numpy from
its source directory; please exit the numpy source tree, and relaunch
your python intepreter from there.

I really need help. I’m using Python 2.7.3 on Ubuntu.

It’s better that use some package management tool such like pip to install numpy.
For example,

pip install numpy
