Question #661017 on Yade changed:
https://answers.launchpad.net/yade/+question/661017

    Status: Open => Answered

Deepak proposed the following answer:
Hi,

If I understand correctly, you intend to run yade under a ''pure python''
environment?  If that's the case you could have a look at these notes in
[1].  You might also want to look at how to instantiate an instance of your
class (having __init()__ method)[2].

An example of python script importing yade as a module is here [3] (this
script is based on one of the example scripts) [4]
