Py3 breakage?

[FlorianHeigl]

I'm just a beginner learning the modules i'll need in the next months, but this seems to be a real issue. I would strongly suggest there's some issue in python compatibilty. I'm running netbox-docker by the way, and added this driver via pip3 install napalm-aos.

the procurve driver just loaded a moment before!

AOSDriver is not compatible with build-in Napalm 3.0 yet, you have to use Napalm version 3.2.1
This PR could fix the problem: #30

[FlorianHeigl]

@jefvantongerloo so nice of you to take time for a reply.
I am a bit confused - isn't 3.2.1 newer than 3.0?

[jefvantongerloo]

Sorry typo, the compatible version is 2.3.1.
When I use and test Napalm 3.0 I get the same error message.

[FlorianHeigl]

Thanks! Hopefully that PR will move forward some day.

[napalmaos]

Please help to test again with latest code

[FlorianHeigl]

It seems to do a lot better now:

floh@blackbox:~/git/netbox-docker$ docker exec -ti netbox-docker_netbox_1 bash
bash-5.1$ python3
Python 3.8.7 (default, Feb 19 2021, 01:11:05) 
[GCC 10.2.1 20201203] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import json
>>> from napalm import get_network_driver

I need to replicate things in an env with AOS switches for actual testing, but it seems you solved the main py3 pain points already!
