loading ntc templates installed via pip fails with "IsADirectoryError"

Hello

when I am using textfsm installed via pip I get this error:

Traceback (most recent call last):
  File "/home/jo/foo/netmiko-bug/test.py", line 4, in <module>
    print(router.send_command("show int desc", use_textfsm=True))

IsADirectoryError: [Errno 21] Is a directory: '/home/jo/foo/netmiko-bug/lib/python3.9/site-packages/ntc_templates/templates'

Environment is: Python 3.9.0 netmiko 3.3.2 ntc-templates 1.6.0 textfsm 1.1.0 venv installed via

python3 -m venv .
source bin/activate
pip install netmiko ntc_templates

The templates and the index file are in /home/jo/foo/netmiko-bug/lib/python3.9/site-packages/ntc_templates/templates as expected. Setting the NET_TEXTFSM environment variable to this path works as expected.

the script I run is this:

from netmiko import Netmiko

router = Netmiko(host="router.example.com", username="admin", password="somepass", secret="somesecret", device_type="cisco_xr")
print(router.send_command("show int desc", use_textfsm=True))

@ktbyers , thanks a lot, issue was resolved after installing the latest netmiko version as you stated, in my venv it was not showing the latest one, appreciate your help and wish you a nice weekend ahead! 😃

Fixed in this PR:

This was a Python 3.9 issue/change.
