I'm trying to animate a trajectory of an object in 2D using python.
The problem is, when i try to do so I get this famous error

I tried every solution I found (installing PyQt5 and importing it, reinstalling matplotlib, updating pip) and nothing works. I still get the same error every time.
I'm on windows 10 and I installed python (3.9.2) using chocolatey. I'm coding with spyder 4.2.2
I've seen someone speaking about how updating his GPU driver helped but mine is up to date and still nothing (Radeon RX580).
Does anybody have a clue on what could be the issue ?
Installing Pyside2 did the trick. No need to for the import PyQt5 if you have the option picked in the preferences of Spyder

I am totally new to Python/Jupyter notebook.
Using Windows 11. I installed latest version python Python 3.11.1. Also latest Anaconda - conda 22.9.0.
My jupyter notebook (installed by anaconda) does not start from command line:

Conda documentation states "Anaconda supports Python 3.7, 3.8, 3.9 and 3.10. The current default is Python 3.9."
Should I just downgrade my python to 3.9 or 3.10 (I dont care) ?? Any other work arounds?
Updates
Could open the jupyter notebook from the conda prompt. Not stated using it yet. So lets see. If python compatibility issues need to be resolved - need to figure it out.
But, cant start the anaconda-navigator. When I try start from windows start menu - does nothing.

Got this error while trying to run some already used python scripts on pycharm. Has anybody had this error before and has he solved it? It started after I installed a package in python but never used it. The problem is located when I try to import train_test_split on scikit-learn and tensorflow, the sklearn package and seaborn. The other parts of the code seem unaffected.
I have already reinstalled anaconda and python as well as changing the python files. Any help would be greatly appreciated.
After reinstalling the python as well as updating all the packages (conda update --all) and changing the PATH file, it seems that the issue is solved in all of my IDE's except PyCharm. It seems that all that remains is an interpreter issue. I will post updates if something else comes into my attention.
I tried to launch of Orange 3 on Anaconda. But launch have produced errors below.

import CommonMark
ModuleNotFoundError: No module named 'CommonMark'
Acutually I found these error on this web and tried to install the r-commonmark 1.4 but it does not work well now.
Please tell me how to deal with it.
CommonMark is a package that Orange used. It was renamed in the latest release what causes that imports do not work. The issue should be solved by installing newer Orange3 version3.16.0
I have written a program that I have tried to turn into an executable using PyInstaller. Pyinstaller appears to have finished without any errors and I end up with an application in /dist/my_program. However, when I try to run that application a console window flashes up for a second with a traceback:
Edit: I have copied the traceback out. There may be a mistake as I had to type it up from a screenshot because it only flashes up.

ImportError: No module named FileDialog
Below are the imports that I have in my code:
import Tkinter
from tkFileDialog import askopenfilename
import numpy as np
import matplotlib.pyplot as plt
import matplotlib.mlab as mlab
from matplotlib.backends.backend_tkagg import FigureCanvasTkAgg
import subprocess
from PIL import Image, ImageTk
import os
Does anyone know whats causing this/what the fix is? I presume the error is the importation of tkFileDialog?
Edit2: the program runs fine when I run it in my interpreter (Spyder) but when I packaged it using PyInstaller the resulting application gives this error.
According to this question adding import FileDialog solves the problem. Matplotlib seems to need this.
However, I've used Pyinstaller on a script of mine also importing matplotlib and it gives no such error. So I don't know what exacly is the problem here.
I have installed numpy1.3,scipy 0.7.1,matplotlib 0.99.1.1 and python 2.5
when I import pylab I get the following error. Someone please help.

try using a different backend for plotting than Gtk.
Open the python console and type:
>>> import matplotlib
>>> matplotlib.matplotlib_fname()
This will print a file name. Edit this file and modify the section 'Backend' and change Gtk or GtkAgg with any other (see the documentation in the same file), until you get it working.
You can find more information about backends here.
As for why you get an error when you try to use that backend, it depends on how you have installed the libraries and what you have installed on your computer. I would recommend to install matplotlib with synaptic/yum and selecting all optional dependencies.
