Previously I installed Numpy for Python-3.4.0. Now that I installed conda, Python-3.4.2 comes with it, instead. So when I run python3 I use Python-3.4.2 instead. And when I call import numpy I get an ImportError. When I try to run sudo apt-get install python3-numpy I get this error saying it is already installed.

How can I resolve this ?

  • Sometimes you can run into problems with different versions of Python that the Python package (e.g. Numpy) that installed and ran successfully on one version of Python doesn't work on an updated version of Python. Sometimes it works, sometimes it doesn't, but even if it doesn't work you can use pip3 (the pip3 package is called python3-pip in Ubuntu) to install the latest version of Numpy using pip3 install -U numpy. – karel Feb 22 '15 at 11:34
  • @karel Thank you for trying to help me. I run that command, it is installed again but I get the same ImportError error message –  Feb 22 '15 at 11:49
