Introduction

Understanding the Issue

Why the Error Occurs:

Inconsistent Library Installation: When libraries such as SciPy and NumPy are installed via different methods (pip vs. conda), they may end up in different directories. This can lead to import errors, as Python may be unable to find the necessary modules.

Local Installation Conflicts: Libraries installed with the --user flag are placed in the user’s local directory (~/.local/lib/python3.9/site-packages). This can create conflicts if other libraries expect these packages to be in the standard Anaconda installation path.

Step-by-Step Solution

1. Identify the Installation Paths for Your Libraries

To troubleshoot the issue, first check where your libraries are installed. You may find that SciPy is located in a different directory than the other packages. Here’s how to verify this:

Look for your library installation paths in your terminal:

This command will provide you with the paths where Python checks for installed packages.

2. Remove or Rename the Local SciPy Installation

If you find that SciPy is located under your .local directory, it’s essential to remove or rename that directory to avoid conflicts:

You can either delete it:

3. Reinstall SciPy Using Conda

After removing or renaming the conflicting directory, you should reinstall SciPy to ensure it is correctly placed under Anaconda’s package structure:

Use the following command to reinstall:

4. Verify the Installation

Once you've reinstalled SciPy, double-check to ensure everything is in order:

You can run the script again to see if the error persists.

Optionally, check installed versions with:
