Nornir 2.5/Python 3.6.x error

[alistair993]

Hello everyone,

I am new to Nornir and started a course on CBT nuggets which is using Nornir 2.5.0 and Python 3.6.9. My docker container is running Python 3.6.13 with Nornir 2.5.0. I tried downgrading Python by using the container Python 3.6.13-slim-stretch but this did not sovle the issue. I have tried Googling but not I'm unable to find a solution :(

I keep getting this error when trying to initialise:

from nornir import InitNornir
nr = InitNornir(config_file="config.yaml")
Traceback (most recent call last):

This is my config.yaml

Thanks!

It looks like something is wrong with your inventory file/structure.

Also, note Nornir 2.5 is deprecated.

Also in fairness probably should ask the CBTNuggets folks for assistance and not us.
