Just installed it. Bad news. Enthought canopy wont work with panda3d. It uses python virtual environments which panda3d is unable to work with (yet). I recommend using another IDE or editor. I personally use Pycharm community edition, others use pydev with eclipse, others use text editors like Sublime Text or Notepad*
If there is specific functionality you are looking for with canopy I can try and help you find a good replacement.
*Please don’t actually use notepad. It will only cause you pain.
