RuntimeError: asyncio.run() in using fetch_gltf in turtorial of Visualizaing a glTF file

[Clarkszw]

I have met a challenge when try this tutorial :Visualizing a glTF file

When I run fetch_gltf('Duck', 'glTF'), Jupyter give me this output:

---------------------------------------------------------------------------
RuntimeError                              Traceback (most recent call last)
Cell In[11], line 1
----> 1 fetch_gltf('Duck', 'glTF')
      2 filename = read_viz_gltf('Duck')

File [~\Desktop\coder\GSoC\FURY\fury\data\fetcher.py:417](https://file+.vscode-resource.vscode-cdn.net/c%3A/Users/Clark/Downloads/~/Desktop/coder/GSoC/FURY/fury/data/fetcher.py:417), in fetch_gltf(name, mode)
    415 if platform.system().lower() == "windows":
    416     asyncio.set_event_loop_policy(asyncio.WindowsSelectorEventLoopPolicy())
--> 417 filenames = asyncio.run(_fetch_gltf(name, mode))
    418 return filenames

    184 if events._get_running_loop() is not None:
    185     # fail fast with short traceback

    189 with Runner(debug=debug) as runner:
    190     return runner.run(main)

RuntimeError: asyncio.run() cannot be called from a running event loop

I have tried to use the downloaded example code, but it gives the same output.

Thank you for the feedback. Can you provide more info about your environment (python version, OS, pip freeze). I will try it tomorrow

[skoudoro]

it can be a jupyter issue with asyncio

more info to look at https://stackoverflow.com/questions/55409641/asyncio-run-cannot-be-called-from-a-running-event-loop-when-using-jupyter-no
