RuntimeError: "There is no current event loop" when running streamlit app with stpyvista about stpyvista

What version of panel is installed in your environment?

``The version of panel installed in my environment is 1.3.8.

However, after several attempts, I decided to downgrade the stpyvista version to see if it resolves the issue. After several downgrades, I found that the version that does not return any error is stpyvista version 0.0.11.

(+) after i add this to my code:

import asyncio

try:
    loop = asyncio.get_event_loop()
except RuntimeError as ex:
    if "There is no current event loop in thread" in str(ex):
        loop = asyncio.new_event_loop()
        asyncio.set_event_loop(loop)
    else:
        raise

👍 I was able to replicate your issue only if running python 3.9. No exception is raised if running python 3.10 or 3.11. I'll check what exactly is going wrong...

It seems this issue has been solved as the Runtime Error is not raised anymore with the latest version of panel.

Tested with:

• Python 3.9.18
• panel 1.4.0
• pyvista 0.43.4
• stpyvista 0.0.16

I'm closing this issue but feel free to reopen if I missed something.
