troubleshooting python script from github

1) python newbie
2) tasked with getting a script together that would compile various stats from our brocade switches
trying to run this script
https://github.com/zapman449/brocade_switchshow_aliases
3) get it set up per the Readme. Config file is set up (I think) properly)
4) BUT - I get the following errors - and not sure why. Any help would be appreciated
[someguy#myserver SAN_Scripts]$ ./get-brocade.py fcr_fd_41
<function parse_switch_line at 0x1429578>

Getting OSError when running script

I am trying to set up the ChirpSDK, but every time I configure and run the code, I get this error:
Traceback (most recent call last):
File "test.py", line 3, in <module>
chirp = ChirpSDK()
File "/Library/Frameworks/Python.framework/Versions/3.8/lib/python3.8/site-packages/chirpsdk/chirpsdk.py", line 395, in __init__

if self._sdk:
AttributeError: 'ChirpSDK' object has no attribute '_sdk'
I realize that the error is saying that my .chirprc file is not being recognized, but I have no idea how to remedy this. I created a .chirprc file in my /Users/username/ path, and named it c.chirprc (as the Chirp getting started article suggests), but I am still getting this error. Is there another part that I am missing? Am I reading the instructions wrong?
Thanks

The Chirp configuration file should be placed at /Users/<username>/.chirprc on macOS.
If you run ls -l ~/.chirprc in the terminal, do you get any results? If it displays no such file or directory then you have not created the file correctly.

signal handler must be signal.SIG_IGN, signal.SIG_DFL, or a callable object

I am trying to write some code to perform some packet sniffing with python
using pyshark.I have the following piece of code:
import pyshark
print('Pyshark demo')
capture = pyshark.LiveCapture(interface='enp0s8')
However when I try to run this script I get the following stack trace:
Pyshark demo

TypeError: signal handler must be signal.SIG_IGN, signal.SIG_DFL, or a callable object
I have install pyshark.Do you have any idea what is causing this problem?
I run this on an ubuntu server 16.04

Pyglet file name "Resource not found"

I'm trying to open a music track and add it to a queue for a player in Pyglet.
def QueueAudio(self):
self.musicpath=filedialog.askopenfilename()
print(self.musicpath)
Player.queue(pyglet.resource.media(r"self.musicpath"))
The musicpath variable works fine as the print statement prints the filename. The error comes when the player tries to queue the track. Error below.
Exception in Tkinter callback
Traceback (most recent call last):
File "C:\Python33\lib\site-packages\pyglet\resource.py", line 605, in media
location = self._index[name]
KeyError: 'self.musicpath'
During handling of the above exception, another exception occurred:
Traceback (most recent call last):
File "C:\Python33\lib\tkinter\__init__.py", line 1475, in __call__
return self.func(*args)
File "C:\Users\Rob\Google Drive\Coursework\Part 2\music player tests\test5.py", line 99, in QueueAudio

raise ResourceNotFoundException(name)
pyglet.resource.ResourceNotFoundException: Resource "self.musicpath" was not found on the path. Ensure that the filename has the correct captialisation.
Does anyone know why this is, and what may fix it?

This line looks to be the culprit:
self.playerpath=pyglet.resource.media(r"self.musicpath")
You are passing a string "self.musicpath" to a function, when you should be passing in the contents of a variable named self.musicpath. You need to call it like this:
self.playerpath = pyglet.resource.media(self.musicpath)
