I'm trying to use the Python 3 version of matplotlib module. I am getting errors about dateutil not being present even though I have installed this package. Shouldn't

import dateutil 

work after installing the above package? I am using Ubuntu 14.04 in case it matters.

No, not using a virtualenv –  user1128171 May 2 at 12:53
    
I uninstalled dateutil and reinstalled it and it is working now. Odd –  user1128171 May 2 at 12:58

First make sure that you are not trying to import the module after activating the virtualenv. If you have your virtualenv activated and didn't supply the argument --system-site-packages while creating it, the module won't be available to you to import in virtualenv.

If you are not using a virtualenv and still unable to import the module, then make sure that you are using the Python 3 interpreter and not the Python 2 interpreter. Since you installed the package for python3, it won't be available to import in python2 interpreter. Next try to purge and reinstall the module using:

sudo apt-get purge python3-dateutil
sudo apt-get install python3-dateutil

Purging the package and reinstalling it should fix any issues which was restricting to import the module.
