This error suggests that there is an issue with your NumPy installation, often due to version compatibility conflicts, especially when using Numba, which relies on NumPy for various numerical computations.

What Caused This?

In your case, the root cause of the problem was compounded due to the version mismatch between NumPy and Numba. Specifically, the error message highlights that:

This means your current version of NumPy (1.26.2) exceeds the maximum version compatible with the installed version of Numba (0.57.1).

Step-by-Step Solution

To resolve this error and move forward with your project, you can follow these steps:

1. Upgrade NumPy and Numba Together

Instead of uninstalling and reinstalling each package separately, the most efficient approach is to upgrade both NumPy and Numba in tandem. You can do this by executing the following command in your terminal:

Using this command ensures that both packages are updated to compatible versions, preventing any dependency conflicts that may arise during the process.

2. Check Your Python Version

Ensure that you are working with the appropriate version of Python (in your case, Python 3.11). The libraries should be compatible with this version, but it’s always a good idea to check the documentation for any version-specific notes.

3. Verify the Installations

After upgrading, you can verify that the installations are correct by running:

If no errors arise, congratulations! You have successfully resolved the issue.

Conclusion

Dependency conflicts can be a headache, but with careful management of your library versions, you can keep your Python environment running smoothly. Always ensure you check compatibility requirements specified in the documentation for the libraries you're using.

If you continue to face issues, consider creating a virtual environment to manage package installations more effectively, isolating your dependencies from the global Python installation.
