Actually you are missing python libraries in your system, you can download and install this first then you may be able to run your script.

I have a Python Code to conduct an experiment. To ensure that the Code is working smoothly I wanted to run a trial round via 'otree devserver', but I always get an AttributeError message and I am stuck here. Can anyone help me out?
I have downloaded the Code from GitHub and downloaded all required packages. I am using macOS, otree-5.10.2 and django-4.1.7. Here is my full traceback / error message:

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')
Error:

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?
I am trying to create a 2D arcade style game for a project in school using Python Arcade in VSCode, but I have issues correctly locating a map I created on a map editor.
Both the game code and map file are situated in the same main folder, with the map being placed in a sub-folder within the main folder.
I have used this line of code to specify the map location:
# Map name
map_name = ("maps/map1_level_{}.tmx.".format(level))
This is the error:
C:\Users\frag>python c:/Users/frag/Documents/game/arcade_game.py
Traceback (most recent call last):
File "c:/Users/frag/Documents/game/arcade_game.py", line 310, in <module>

raise FileNotFoundError(f"Cannot locate resource : {path}")
FileNotFoundError: Cannot locate resource : maps\map1_level_1.tmx
try this map_name = ("./maps/map1_level_{}.tmx.".format(level))
Fixed the issue by specifying the working absolute path:
import os
os.chdir('C:/Users/frag/Documents/game')
Env:
Ubuntu 18.04
Python 3.6.6
pyglet 1.3.2
Issue:
Based on documentation of pyglet I try to run following code:
import pyglet
pyglet.options["audio"] = ("openal", "pulse", "directsound", "silent")
explosion = pyglet.media.load('explosion.wav')
But following exceptions occured:
1) if file was converted by ffmpeg -i input.mp3 output.wav
Traceback (most recent call last):

explosion = pyglet.media.load('zxc.wav', streaming=False)

Question:
How to run .wav files via pyglet correctly?
Like in the example, it is probably either an issue with openal or the wav-files. Are the procedural sounds playing correctly, e.g.:
from pyglet.media.sources.procedural import Sine
sine = Sine(duration=1, frequency=500,
sample_size=16, sample_rate=44100)
pyglet.media.StaticSource(sine).play()
and can you share an offending wav-file? I just ran a test on Linux Mint 19, Python 3.7.1 and pyglet 1.3.2 with https://github.com/pyreiz/pyreiz/blob/master/reiz/media/wav/ding.wav and it runs fine.
I have the virtualbox 5.0.10 Python sdk in my source root, but when I run my code the program will fail:
Traceback (most recent call last):

return mapCLSIDToClass[clsid]
KeyError: '{7844AA05-B02E-4CDD-A04F-ADE4A762E6B7}'
Here is my code: (really simple, right?)
import vboxapi
mgr=vboxapi.VirtualBoxManager()
This program is buggy under Python 2.7.6, but runabble under Python 3.4.0.
Why? How can I fix that?
