Hi, I am trying to communicate between a ROS2 machine(Linux VM) and a non ROS machine(Host Windows). I have configured the network connections. When I install ROS on the windows machine as well, and run a demo talker on Windows and a listener on Linux, they communicate. Now when I try to run the demo talker using rclpy, it doesnt.

In windows, from the terminal, I run the demo_nodes_py talker.py and I get the error : Traceback (most recent call last): File "listener.py", line 17, in <module> import rclpy ModuleNotFoundError: No module named 'rclpy'

Any idea how to use the rclpy API ? What am I doing wrong here ?

But Now I want to run these two on different machine for example I want to run my publisher on my windows host machine and the listener on Linux vitrual machine. Where can I set the endpoints for pub&sub in rclpy lib so that my publisher on windows can send data to the listener running on Linux VM.

Any help would be appreciated.
