PYMEL: "from pymel import *" Not Working?

If you're trying to get Pymel installed on your machine and it seems to be working but nothing happens when you import the modules into Maya, read on.

The Pymel documentation currently tells you to type:

from pymel import *

But the latest release (1.0.0.rc1) will not work with this method on a new installation. We've tested it on about a dozen machines and so far all of them require a slight change, which is to type the following:


from pymel.core import *

There may be a simple work-around for this, but if you follow the installation instructions from scratch on a machine with no previous installs, you will need to do this to get the pymel modules to import into Maya.

What is Pymel? From the site:

Python in Maya Done Right

PyMEL makes python scripting with Maya work the way it should. Maya's command module is a direct translation of mel commands into python commands. The result is a very awkward and unpythonic syntax which does not take advantage of python's strengths -- particulary, a flexible, object-oriented design. PyMEL builds on the cmds module by organizing many of its commands into a class hierarchy, and by customizing them to operate in a more succinct and intuitive way.

Check out the Pymel website for more information.
