Waveshare 2.9inch_Touch_e-Paper_HAT: Getting Demo to work - python

I thought I just share m findings if anybody else has bought the same e-paper touch display and struggles to start the demo on a raspberry pi (python).
In my case I followed the wiki page:
https://www.waveshare.com/wiki/2.9inch_Touch_e-Paper_HAT
But then there was no "main.py" to start, so I figured i tried the existing file "TP2in9_test.py".
After doing "chmod -x TP2in9_test.py" I started the file with
sudo python3 TP2in9_test.py but got an error:
Traceback (most recent call last):
File "/home/pi/Touch_e-Paper_Code/python/examples/TP2in9_test.py", line 14, in <module>
from TP_lib import weather_2in9_V2

font12 = ImageFont.truetype(os.path.join(fontdir, 'Font.ttc'), 12)

return freetype(font)

File "/usr/lib/python3/dist-packages/PIL/ImageFont.py", line 209, in __init__
self.font = core.getfont(
OSError: cannot open resource
I then commented out both lines that referenced the "weather" script/function, that is lines 14 and 112.
After that the display demo works and even the weather part is showing up, nice.

Solution: Comment out both lines that referenced the "weather" script/function,
that is lines 14 and 112.

Simple Python pytube code not working anymore

This is just simple Python code that worked when I first ran it, but didn't work the next day, even though I didn't change anything:
from pytube import YouTube

video = YouTube(link)
yt = video.streams.get_highest_resolution()
yt.download("Lieder")

Using pytube on PyCharm

I have a script, which has been working fine in April 2021 when I created it, but now it gives me the following error. I'm not very experienced in coding, so if anyone can help me it would be great.
What I'm trying to do is simply download a song from youtube as a mp4. I can see that the error says there is something wrong with the pytube module imported, but I am not skilled enough to see what it is.
I'm using MacOS 12.1, Pycharm 2020.3, and Python 3.9.
Script:
import pytube
url = str('https://www.youtube.com/watch?v=gJLIiF15wjQ')
youtube = pytube.YouTube(url)
video = youtube.streams.get_by_itag(140)
video.download(output_path='/Users/clarajacobsen/Documents/TrueFIR/Klub100/Songs/', filename='test')

AttributeError: 'NoneType' object has no attribute 'span'
To fix this issue, This doesnt depends on which operating system you are on or which python you are using. Follow these steps:
I used Colab for this, if you are using Google colab use it and test it.
Install Pytube with !pip install pytube
After installing pytube just shutdown the kernel and the application you are using for it. either VSCode, Jupyter notebook or Colab. shut down its kernel.
Then run the enviroment again and try importing and running your code.
It should run now.
or if it gives you the same error as before:
Go to the files where pytube is install and go to folder in pytube named "pytube" then go into "cipher.py" and open it.
Search for the line: 293. Where name = re.escape(get_throttling_function_name(js))
Replace name = "iha"
Then close all kernels and file you are running the code on. and restart them completely after shutting down.
These two solutions should work 100%. Solution that worked for me is first one.
As the error tells us, you have a NoneType object called youtube in line 8 which was created before in line 7. Did you check if the YouTube link or anything on that video page that concerns you has changed?

pytube.exceptions.RegexMatchError: __init__: could not find match for ^\w+\W

so my issue is I run this simple code to attempt to make a pytube stream object...
from pytube import YouTube
yt = YouTube('https://www.youtube.com/watch?v=aQNrG7ag2G4')
stream = yt.streams.filter(file_extension='mp4')
And end up with the error in the title.
full error:

pytube.exceptions.RegexMatchError: __init__: could not find match for ^\w+\W
Extra data:
python version: 3.8.10
pytube version: 11.0.2
As juanchosaravia suggested on https://github.com/pytube/pytube/issues/1199, in order to solve the problem, you should go in the cipher.py file and replace the line 30, which is:
var_regex = re.compile(r"^\w+\W")
With that line:
var_regex = re.compile(r"^\$*\w+\W")
After that, it worked again.
To go cipher.py in the pytube site packages
Change line 30
var_regex = re.compile(r"^\w+\W")
to
var_regex = re.compile(r"^$*\w+\W")
"^" means search beginning of the line
".*" means zero or more of any character
"$" means to end of line

Getting 2 errors while converting MP3 to WAV

I am trying to play mp3 file using pyglet module.
Following some suggestions, I have already installed avbin64 and moved avbin64.dll to the directory where my python code is. but still, I am getting 2 errors

music = pyglet.resource.media('song.mp3')
music.play()

As per "Loading media", you're supposed to open audio (and video) files with pyglet.media.load:
music = pyglet.media.load('song.mp3')
You must also have ffmpeg installed for pyglet to be able to read mp3 files (as per Supported media types). Make sure to follow the installation instructions.

However, when I run the app from my terminal, or from my text editor (I use VSCode), It runs with no problems whatsoever. I've looked online and every answer I see has something to do with Rasa, but nothing mentions problems with PyCharm.
I've also checked that the yaml for the domain is properly formatted, and it is. Anyone have any idea why I would be getting this error in PyCharm, but not in any other environment, and how I could fix it?
I believe your problem was fixed with Rasa version 0.12 ([changelog][1]): https://github.com/RasaHQ/rasa_core/blob/master/CHANGELOG.rst#0120---2018-11-11 .
I recommend upgrading to a newer version of Rasa Core which parses the training data correctly.
