When I try to run "import matplotlib.pyplot as plt", I receive the following error: "ModuleNotFoundError: No module named 'PIL'"

EDIT: I noticed that this problem only occurs when I'm using Jupyter Notebook. When I tried to use Google Colab, it worked fine. Is there a way to resolve this issue?

I tried uninstalling and installing pillow, image, and even matplotlib, but I keep receiving the same error. Note that when I try to run "import image", "import pil" and "import matplotlib", they all worked fine.

This is the exact message:

ModuleNotFoundError Traceback (most recent call last)

Try importing like this

import PIL as Image

It's import PIL not import pil. Normally you should also be able to see which line causes the error. There is nothing wrong with the matplotlib import that you mentioned.

  1. First, install PIL through command line python -m pip install pillow.

  2. Second, use it, do in your script from PIL import Image.

I found that this issue only occurred when using Jupyter Notebook, so after several tries I uninstalled Anaconda and reinstalled it and now it works.
