It seems you are trying to run Python program, which uses mido. Mido can use python-rtmidi as a backend, but you have to specify, which backends to install, when you install mido:

You are trying to build python-rtmidi with a 32-bit version of Python on a 64-bit version of windows. Also, your Python version (3.8) is rather old, and support for it will end in two months:

https://www.python.org/downloads/

The python-rtmidi project does not provide binary wheels for windows and Python version 3.8. So you are on your own there, sorry. I don't have the capacity to support that.

Try upgrading your Python installation to the latest 64-bit version.

Which Python version 32-bit is supported by Python rtmidi library，I want to use 32-bit Python

I'm not sure. The python-rtmidi project only provides binary wheels for 64-bit Python on Windows. These are built by our CI (GitHub actions). I don't have a Windows system to test building different combinations myself.

You can try building python-rtmidi manually from the source yourself:

https://spotlightkid.github.io/python-rtmidi/install-windows.html

Try with the latest Python 3.12.5, I guess.

Alternatively, you can check whether you have more luck with other midi backends.
