Which part of the library is the implementation of NEURAL PROBABILISTIC MOTOR PRIMITIVES FOR HUMANOID CONTROL?

[Rakesh-Paul01]

Hi I am a student trying to understand this library and training inverse RL I want to do implement work similar to NEURAL PROBABILISTIC MOTOR PRIMITIVES FOR HUMANOID CONTROL. Mentioned here is that the the implementation was adapted yet I struggle to find it. Could you'll direct me where to mind the relevant source code for the implementation.

Thank you.
