it say ModuleNotFoundError: No module named 'matplotlib'

I tried reinstalling matplotlib several times and every solution i could find on google, nothing seems to work.

A lot of things can make your code not to find the module, one of the common problem is having multiple python versions installed on your computer. Using a virtual environment to manage the project will help fix such problems on your project.

• On your project directory, create a virtual environment with venv
  python3 -m venv workspace
  workspace is the name of the environment, you can give it any name you want

• Activate the virtual environment
  On PC use this code
  workspace\Scripts\activate.bat
  On Mac/Linux
  source venv/bin/activate

• Install matplotlib in the virtual environment and run your code

When you are done you could deactivate the environment with this code
deactivate
