This might happen when you're working with popular libraries such as Pandas or Matplotlib, especially in a development environment like PyCharm. Let’s break down this issue and guide you on how to correct it.

The Problem

When you try to run your script, you might see the error message similar to the one below, indicating that there is something wrong with the versioning structure in your installation of the library.

Here’s what you might see:

This error occurs when the code is attempting to access an __version__ attribute from the __version_info__ object, which doesn’t actually exist in the context it’s being called.

Why This Happens

The issue arises because:

The __version_info__ object in Python is meant to store versioning information in a structured format, but it doesn’t contain a direct __version__ attribute.

Many libraries define version numbers differently, and attempting to access a nonexistent attribute leads to this AttributeError.

The Solution

To resolve this error, you will need to modify the way you handle the versioning in your script. Follow these steps:

Locate the Code Section: Find the line in your script or library where the error arises. This will typically look like this:
