I want to call OpenModelica from asynchronous code using trio, but cannot do so.
import trio
from omc4py import open_session
async def main() -> None:
with open_session(asyncio=True) as session:
await session.getVersion()
if __name__ == "__main__":
trio.run(main)
$ python trio_omc.py
/home/ijknabla/sandbox/python/.venv/lib/python3.12/site-packages/zmq/_future.py:708: RuntimeWarning: No running event loop. zmq.asyncio should be used from within an asyncio loop.
self._update_handler(self._state)

Are you trying to use a library written for some other framework like asyncio? That won't work without some kind of compatibility shim.
