ns 3 - ns3-ai: AttributeError: module 'py_interface' has no attribute 'Init'

Question

I have added ns3-ai to my ns3.32 version(I have tried with ns3.30 also), but when running example(rl-tcp) I get the following error:

Traceback (most recent call last):    
File "testtcp.py", line 28, in   
py_interface.Init(1234, 4096)   
AttributeError: module 'py_interface' has no attribute 'Init'   

Why is this?
my python version is 3.7 but also I have python 3.6 and python 3.8 and python 2.7. and Im using ubuntu 18.04
