ModuleNotFoundError: No module named 'PIL'

Question

I am getting an error.

#! /usr/bin/python3
# On 10/4/22 I installed version Python 3.10.7
# png2jpg.py    
# Does not work

# Traceback (most recent call last):
  # File "/home/andy/Python/png2jpg.py", line 10, in <module>
    # from PIL import Image
# ModuleNotFoundError: No module named 'PIL'

import math 

import os
import sys
from PIL import Image

if len(sys.argv) > 1:
    if os.path.exists(sys.argv[1]):
        im = Image.open(sys.argv[1])
        target_name = sys.argv[1] + ".jpg"
        rgb_im = im.convert('RGB')
        rgb_im.save(target_name)
        print("Saved as " + target_name)
    else:
        print(sys.argv[1] + " not found")
else:
    print("Usage: convert2jpg.py <file>")

I installed Pillow.

pip3 install Pillow

which pip3

/usr/local/bin/pip3

I use python3 png2jpg.py

pip3 --version
pip 22.2.2 from /usr/local/lib/python3.10/site-packages/pip (python 3.10)

I did find out that the python script does work in UM 20.04.

I tried some new items from Michael Mba.

pip uninstall PIL
Cannot uninstall requirement PIL, not installed

python3 -m pip install --upgrade pip

I have no pip.conf file? :-)

Python allows you to set default command-line options with the help of pip.conf file.

Locate your pip.conf file based on your operating system -

2. Unix - $HOME/.config/pip/pip.conf

Can you update your question to include the output of `which pip3`? Also, how are you running your code (by running `./myscript.py` or `python myscript.py` or `python3 myscript.py` or something else)? — larsks, Oct 05 '22 at 17:36
It looks like you may have two versions of Python installed. If you run `/usr/local/bin/python3`, are you able to `import PIL`? — larsks, Oct 05 '22 at 18:34
runing /usr/local/bin/python3 gives the same message. Python 2.7.17 was installed with my Ubuntu Mate installation. I thought about removing it but read somewhere that to do so would cause a lot of problems. @larsks — fixit7, Oct 05 '22 at 18:53
Right, you **do not** want to remove the system Python! But that shouldn't be an issue in any case because you're explicitly running `python3`. What does `pip3 --version` output? — larsks, Oct 05 '22 at 18:56
pip3 --version pip 22.2.2 from /usr/local/lib/python3.10/site-packages/pip (python 3.10) @larsks — fixit7, Oct 05 '22 at 19:36

After some reading and experimenting, this worked for me:

pip uninstall PIL
python3 -m pip install --upgrade pip
python3 -m pip install --upgrade Pillow

I also read that changing "PIL" to "pil" worked as a solution for some.

I hope this helps.

I tried your suggestions and added the results to my post. – fixit7 Oct 07 '22 at 02:31
Hey @fixit7 looked at the error message from your pip upgrade attempt. I do not know the state of your network so rather than suggest multiple things here's a link that may help. https://jhooq.com/pip-install-connection-error/ [link](https://jhooq.com/pip-install-connection-error/) – Michael Mba Oct 07 '22 at 03:02
