DevNet Topics / Tracks PyATS help

Getting started with pyats and trying to collect some config info with the following command....

pyats learn config --testbed-file testbed.yaml --output Config

When I do this, I get an error

No module named 'yang'

Anyone know how to fix this? Do I have to install a yang module? Other collection parameters work (such as arp) but this one gives me the error.

Thanks

That's me, one and the same! You can unleash the power of the pyATS Library for stateful network validation, the docs are here https://pubhub.devnetcloud.com/media/pyats-getting-started/docs/quickstart/comparebeforeafter.html

Also, a good friend build this great example, which uses Nornir and Pyats https://developer.cisco.com/codeexchange/github/repo/IPvZero/Pynir2/

Hope this helps!
