ImportError: No module named gaussian

[lyh458]

Thanks for your nice work!
When I tryed to follow the robot_example, it will show this error. I check the source code of intprim and can not find gaussian.py in the folder "/intprim/util/".

Reproducing code:

roslaunch intprim_framework_ros interaction_application.launch

Error message:

Traceback (most recent call last):
  File "/home/lyh/Codes/hri_ws/src/intprim_framework_ros/scripts/intprim_service.py", line 16, in <module>
    import intprim.util.gaussian
ImportError: No module named gaussian
