Solving the Module not found Error in Matplotlib: Understanding the pylot Typo

When working with Python and its numerous libraries, it's not uncommon to encounter installation issues and module errors. One such problem faced by many developers is the Module not found error, especially when trying to import modules from Matplotlib.

Recently, a user experienced this issue with the following scenario: they received messages indicating that all requirements were satisfied upon trying to install Matplotlib using pip, yet an error persisted while trying to import it in their code. They received a traceback that pointed to a non-existent module called pylot. Let’s dive into the issue and how to fix it.

Understanding the Problem

The user's installation steps were straightforward:

They executed pip install matplotlib in the command line.

Upon trying to import the library using import matplotlib.pylot as plt, they encountered the error:

This will display information about the Matplotlib installation, including version and location.

Additional Notes on Installation Issues

While the typo is most likely the root cause of the error, users may sometimes face other installation issues, such as:

Permission Errors:

The user also reported an Access Denied error when trying to install Matplotlib. This can happen if you don’t have administrative rights on your machine. To resolve permission errors, you can either:

Run your terminal as an administrator.

Use the --user option to install packages at the user level:
