How can I convert a Python 2.7 CLL call to a Python 3.11 version when encountering an issue with libgfortran_64-3.dll?

edit

To convert a Python 2.7 CLL call to a Python 3.11 version, you will have to update the code and make use of the standard libraries and functions available in Python 3.11.

If you encounter an issue with libgfortran_64-3.dll, you can try the following steps to resolve it:

1. Install the latest version of MinGW-w64 on your system, making sure that the architecture matches your Python version (32-bit or 64-bit).

2. Download the appropriate pre-built binaries of libgfortran for your Python version and architecture. You can find them on the official GNU website or on other third-party sources.

3. Copy the libgfortran DLL file to the same directory as your Python script or add it to your system's PATH environment variable.

4. Run your Python script and check if the issue with libgfortran_64-3.dll has been resolved.

Alternatively, you can also try installing the numpy package using pip in your Python 3.11 environment since it includes pre-built binary distributions of libraries like libgfortran as dependencies.
