IMU problem - MacArthur HAT on RPi4

[sealgair]

Hi 
Building a Pi4 based system for my boat. Got a MacArthur HAT with ICM-20948

Followed install process for Pypilot and IMU recognised but Pypilot does not allow 'Enable IMU only' option.

Shows 4.0.11-beta as installed

Dialog contains 
pypilot version: No module named 'pypilot'

and 

All services disabled

Wondering where to go from here to get the IMU working so I can include the data in SignalK output??

As the IMU is recognized, it looks like the MacArthur side is working. You are more likely to get an answer to your question in the PyPilot section of this forum.
