Setting up vicon for indoor flight test

Is there an alternative way to setup vicon for ardupilot? I followed the steps here: Using a Vicon indoor positioning system — Copter documentation but I keep getting this error:
Traceback (most recent call last):
File “/usr/local/bin/mavproxy.py”, line 517, in load_module
m = import_package(modpath)
File “/usr/local/bin/mavproxy.py”, line 673, in import_package
mod = import(name)
ModuleNotFoundError: No module named ‘vicon’

Hello
Did you installed pyvicon ?

Yes I followed the exact steps detailed in the documentation
