Which version of napalm do you have ?

[Laurens Wijnsma]

napalm==4.0.0

Which version of napalm do you have ?

[Łukasz Kostka]

Weird. Code works and it's tested on CI with python 3.8. Can you print out all attributes of Version object ?
at https://github.com/napalm-automation-community/napalm-ros/blob/master/napalm_ros/ros.py#L345

print(dir(pkg_resources.get_distribution("napalm").parsed_version))

print(dir(pkg_resources.get_distribution("napalm").parsed_version))

This is the output of that command:

['__class__', '__delattr__', '__dict__', '__dir__', '__doc__', '__eq__', '__format__', '__ge__', '__getattribute__', '__gt__', '__hash__', '__init__', '__init_subclass__', '__le__', '__lt__', '__module__', '__ne__', '__new__', '__reduce__', '__reduce_ex__', '__repr__', '__setattr__', '__sizeof__', '__str__', '__subclasshook__', '__weakref__', '_compare', '_key', '_regex', '_version', 'base_version', 'is_postrelease', 'is_prerelease', 'local', 'public']

[Laurens Wijnsma]

And this is the output of :

>>> print(pkg_resources.get_distribution("napalm").parsed_version)
4.0.0

[Łukasz Kostka]

parsed_version should return Version object e.g.

In [6]: ipy = pkg_resources.get_distribution('ipython')

In [7]: ipy
Out[7]: ipython 7.31.0 (/opt/homebrew/lib/python3.9/site-packages)

In [8]: ipy.version
Out[8]: '7.31.0'

In [9]: ipy.parsed_version
Out[9]: <Version('7.31.0')>

Try to upgrade setuptools and pip to newest versions.

Try to upgrade setuptools and pip to newest versions.

pip was already on the latest version but upgrading setuptools from 44 to 65 did the trick.
thank you for the help
