Plugin NBInventory2 is not registered

I have been using Nornir 3.0.0 with python 3.6 after upgrade from ubuntu 18 to 20 and python upgrade to 3.8 and Nornir 3.1.1 i am suddenly seeing this error:

Traceback (most recent call last):

raise PluginNotRegistered(f"plugin {name!r} is not registered")
nornir.core.exceptions.PluginNotRegistered: plugin 'NetBoxInventory2' is not registered

I am using it like this:

#!./venv/bin/python

from nornir import InitNornir
from netbox import NetBox

nr = InitNornir(config_file="./config.yaml")

How do i register plugin NetBoxInventory2?

You don’t have to, the plugin does it on its own. You only have to install it so I am guessing you didn’t.

You are correct. I have rebuilt the virtual environment and even though i had nornir_netbox plugin in the requirements file i had to manually install it again for some reason. I just assumed it was all installed. Thank you for the prompt reply.
