How to update to the latest numpy and scipy on Ubuntu 14.04LTS

On my Ubuntu 14.04LTS, for python3, I have

 >>> import numpy
 >>> import scipy
 >>> numpy.__version__
 '1.8.2'
 >>> scipy.__version__
 '0.13.3'

I want to update numpy and scipy to the most recent version 1.9.2 and 0.16.0, I tried with the following commands

sudo pip3 install --upgrade numpy
sudo pip3 install --upgrade scipy

both commands ran successfully, but the version numbers didn't change to 1.9.2 and 0.16.0 at all for both python packages (after restarting the computer). Anyone knows how to update to the most version? Thank you very much!!

Solution 1:

I found @David Foerster's comment quite helpful. I also had python3-numpy and python3-scipy installed, which was overriding my later install, so I simply issued:

sudo apt-get remove python3-numpy

And then all the proper versions were already there, as revealed by

pip3 show numpy

Solution 2:

I had the same problem: sudo pip install --upgrade <package> ran correctly but the packages didn't actually get upgraded.

I just tried

sudo easy_install --upgrade numpy
sudo easy_install --upgrade scipy
sudo easy_install-3.4 --upgrade numpy
sudo easy_install-3.4 --upgrade scipy

and it worked: I now have numpy 1.11.0b3 and scipy 0.17.0 in both python and python3.
