error: AttributeError: module 'rtmidi' has no attribute 'MidiOut'

[antkn33]

I'm on macos 15. Python in a venv with 3.9.21

import rtmidi
import time

midiout = rtmidi.MidiOut()
ports = midiout.get_ports()

Are you sure you really installed this package? Not another package, which uses the Python package name rtmidi?

See the install instructions, if unsure.

Looks like you're right but why are there two python packages with the same name???

[SpotlightKid]

Well, first there was one and then there came another (though the first commit of the latter package was a few weeks before the former, it was registered on PyPI much later).

PyPI does not enforce unique Python package names (as opposed to distribution package names).
