Nornir2: can't import napalm_get

[RuiMeireles]

I am getting a circular dependency error when trying to do: from nornir_napalm.plugins.tasks import napalm_get If I just import nornir_napalm there's no problem

I am running Python 3.8.5, with the latest nornit modules.

(venv-3.8) ruimeireles@rui-ubuntu:~/git/automation-poc$ pip3 list | grep nornir
nornir                       3.0.0               
nornir-jinja2                0.1.0               
nornir-napalm                0.1.1               
nornir-netbox                0.1.1               
nornir-netmiko               0.1.1               
nornir-scrapli               2020.10.10          
nornir-utils                 0.1.0

Here's the output I get when I do from nornir_napalm.plugins.tasks import napalm_get

ImportError: cannot import name 'CONNECTION_NAME' from partially initialized module 'nornir_napalm.plugins.connections' (most likely due to a circular import) (/home/ruimeireles/.local/lib/python3.8/site-packages/nornir_napalm/plugins/connections/__init__.py)

Is this a bug? How can I import this command?

[RuiMeireles]

It seems like the module can't find the tasks package.

I've checked, and the files are present:

Closing as this is not the place to report issues on plugins. If there is an issue with a plugin report it to the plugin, please.

The issue is most likely the filename of your script. Rename napalm.py to something else as you are probably shadowing napalm library namespace

[RuiMeireles]

Oh, what a dumb mistake. Yes, it was indeed caused by my script being named 'napalm.py'.

Thanks David.
