Python and pygame error message "image not found"

I've installed python 3.8.7 on my mid 2009 macbook pro,and can't seem to properly install pygame on it. I've gone into terminal and installed it using the command "pip3 install pygame" which seemed to work fine, but when I try to import it in python it comes up with the error message "image not found". If anyone could help it would be greatly appreciated.

as user "ModoUnreal" said in that post
(Error while import pygame)
"A. Check if you have a 64 or 32 bit version pygame and make sure your version of python is the same.
B. Use something like pip install or any other type of method to install pygame.
C. Install a previous version of pygame and python, you might have some more luck with that.
The error is basically saying that a class in pygame called image could not be found. Obviously pygame has not been installed properly so I would suggest using the above methods to install it again.
I hope this helps!"

Import Error - (Python 2.7)

I've been trying to solve an import error I've been getting the whole day and it's just driving me crazy. I've literally went through every Stack Overflow similar question and tried out every single solution and nothing seems to do the magic for me.
I'm currently running a script on my Terminal by doing
$ python camelcamelcamel-import.py
The error I'm getting is:
Traceback (most recent call last):
File "camelcamelcamel-import.py", line 1, in <module>
import sys, mechanize, lxml.html
File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/lxml/html/init.py", line 54, in <module>

Referenced from: /Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/lxml/etree.so
Expected in: dynamic lookup
I've tried installing/uninstall the modules, the same thing for pip and nothing seems to work for me.
Any help would be extremely appreciated, thank you!

Reinstall libxslt and libxml2 using brew.
brew install libxslt libxml2
If you see errors during install, execute this:
xcode-select --install

After installing opencv, python gives Import Error saying it can't find library

I'm using Kivy on Mac OS X. I installed opencv under Kivy's virtualenv. But then when I tried
import cv2
it gave me this Import Error:
Traceback (most recent call last):
File "", line 1, in
ImportError: dlopen(/Applications/Kivy.app/Contents/Resources/venv/lib/python2.7/site-packages/cv2.so, 2): Library not loaded: lib/libopencv_reg.3.1.dylib
Referenced from: /Applications/Kivy.app/Contents/Resources/venv/lib/python2.7/site-packages/cv2.so
Reason: image not found
But if I move to: cd /path/to/opencv/build
then run python and import cv2, it works fine.
It looks like Python couldn't find the library files from the build/lib directory.
Everything looked fine during the cmake bulding and installation process. What am I missing here?
Thank you!!

Cannot use MySQLdb in python (newbie)

After downloading MySQLdb from sourceforge here, I ran setup.py to install it. Now when I try to import "MySQLdb" I get the following error:
>>> import MySQLdb
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/Library/Python/2.7/site-packages/MySQL_python-1.2.4b4-py2.7-macosx-10.9-intel.egg/MySQLdb/__init__.py", line 19, in <module>

Referenced from: /Library/Python/2.7/site-packages/MySQL_python-1.2.4b4-py2.7-macosx-10.9-intel.egg/_mysql.so
Reason: image not found
I'm new to python so I'm not really sure what this means. Can anybody help me figure out how to alleviate this error? Thank you!!!

You need the mysql client library to build MySQLdb. The easiest way that I know of to install it in Mac OS X is to get homebrew and then install mysql with:
brew install mysql
Extra bonus - you can easily install python 3 using brew as well.

ImportError: No module named qgis.core

I am on Ubuntu 13.04. I get the following error message -
Traceback (most recent call last):
File "analyse.py", line 1, in <module>

ImportError: No module named qgis.core
Actually, everything was working fine till today morning. I guess this might be due to a package update.
I tried looking around on Google but my search was fruitless. So, I will really appreciate any help or pointers you guys can give :)
Thanks.

I solved the problem by completely removing the installation and using the nightly builds at 'deb http://qgis.org/debian-nightly raring main'.

If you have pip installed you could either try pip search qgis or pip freeze. The latter shows a list of all installed python packages to check if you have the package. Maybe try reinstalling qgis ...

Try sudo apt-get install python-qgis . The package does not appear to be available on PyPI, but it was listed as "python-qgis" in the Ubuntu packages.
