RuntimeError: no running event loop

[paryasoleimani]

Hey, dear Devs. I was recently testing a robotic example Colab Link running on Swift. It strangely gave me the following error: "Async event loop already running. Adding coroutine to the existing event loop." Exception in thread Thread-11 (SwiftSocket): Traceback (most recent call last): File "/usr/lib/python3.10/threading.py", line 1016, in _bootstrap_inner self.run() File "/usr/lib/python3.10/threading.py", line 953, in run self._target(*self._args, **self._kwargs) File "/usr/local/lib/python3.10/dist-packages/swift/SwiftRoute.py", line 296, in __init__ start_server = websockets.serve(self.serve, "localhost", port) File "/usr/local/lib/python3.10/dist-packages/websockets/asyncio/server.py", line 737, in __init__ self.server = Server( File "/usr/local/lib/python3.10/dist-packages/websockets/asyncio/server.py", line 281, in __init__ self.loop = asyncio.get_running_loop() RuntimeError: no running event loop"

Or it stuck on loading for a long amount of time . How should I solve this?

I really appreciate any help you can provide.

Hi,I had solve that issue ,by this method:
my code:
_import roboticstoolbox as rtb

model = rtb.models.URDF.UR10()
print(model)
qz = [0,30,-30,0,0,0]
model.plot(qz,backend = 'swift')_

fast fix
pip uninstall websockets
pip install websockets==13.1

but the pycharm open with the google,with the error:
Application error: a client-side exception has occurred (see the browser console for more information).
