Fixing the .exe Closure Issue During Matrix Multiplication in Python

When working with Python applications, especially those packaged into executable files using Pyinstaller, you might encounter unexpected behavior. One common issue that developers face is their executable (.exe) closing unexpectedly while performing operations such as matrix multiplication. This guide will dive into this specific problem, particularly when using libraries like Numpy and PyQT5 in a Python project created in Anaconda.

Understanding the Problem

Imagine you have a Python application that performs complex calculations, particularly matrix operations. After converting your Python script into an executable with Pyinstaller, you may notice that the application works perfectly fine when run from the Anaconda Prompt, but encounters problems when opened directly by double-clicking the file or from a command line interface (cmd). Here’s the scenario:

You have two matrices, A with a dimension of [986 x 8] and B with a dimension of [8 x 8].

When you attempt to perform matrix multiplication (either using A @ B or A.dot(B)), the executable closes suddenly without error messages or warnings.

This mysterious behavior can be frustrating, especially when the script itself functions flawlessly in the development environment.

The Cause of the Issue

After thorough investigation, we will outline a common culprit behind this issue. It turns out that the closure of the executable is often linked to how certain libraries, particularly Numpy, have been installed and configured in a project environment created by Anaconda.

Key Points to Consider:

Environment Mismatches: Pyinstaller can sometimes struggle with libraries that are not properly installed in the current environment.

Execution Context: Running the .exe from Anaconda Prompt ensures that the environment variables and library paths are correctly configured, which is why it works there but fails elsewhere.

Dependencies: Some dependencies might not have been included correctly in the executable, leading to runtime errors.

The Solution

Fortunately, the solution to the problem is relatively straightforward. Follow these steps to resolve the issue:

Step 1: Reinstall Numpy

Open Anaconda Prompt: Make sure to run it as an administrator to ensure you have the necessary permissions.

Reinstall Numpy: Use the following command to reinstall Numpy. This ensures that you have the latest version and that any corrupted files are replaced.

Step 2: Test Your Executable

Once the reinstallation is complete, recreate your executable using Pyinstaller.

Run the .exe file again by double-clicking or through the command line (cmd).

Step 3: Verify the Outcome

If everything has been done correctly, the executable should now function without closing unexpectedly during matrix multiplication. Run different test cases to ensure stability.

Conclusion

The problem of an executable closing unexpectedly during matrix operations can often be traced back to installation issues within the working environment. By ensuring that your libraries, especially Numpy, are correctly installed, you can avoid such frustrating pitfalls. If you ever encounter the .exe closing without warning, always consider checking your library installations, as they may hold the key to your solution.

By following the outlined steps, you can get back to your project with confidence that it will run smoothly, regardless of how you launch your executable. Happy coding!
