How do I access orange on Ubuntu 16.04 I have used pip to install orange and the installation seemed fine.  There was not Orange icon on my ubuntu 16.04 desktop and tried orange3 in the command line, it didn't work, and tried python3 -m orange and python3 -m orange 3 and neither worked as well.

How can I use orange?
From the Orange3 Pypi documentation :

To start Orange GUI from the command line, assuming it was successfully installed, run:
orange-canvas # or python3 -m Orange.canvas
