Setting up Python virtualenv

Make IPython work under virtualenv

source testenv/bin/activate

   File "/usr/bin/ipython", line 11
   print "Could not start qtconsole. Please install ipython-qtconsole"
                                                                     ^

This can be resolved by adding a soft link with the name ipython to the bin directory in the virtual environment folder. <source lang='bash'> ln -s /path/to/virtenv/bin/ipython3 /path/to/virtenv/bin/ipython </source>
