Sketch & streamlit

[arri]

Hi guys,
I have been using the sketch library in JupyterLab without any issues (https://pypi.org/project/sketch/). However, when I tried to use it in Streamlit, I encountered an error that says:
“RuntimeError: There is no current event loop in thread ‘ScriptRunner.scriptThread’.”

Hi all, I was trying to work with this library on the streamlit cloud, but the import doesn’t seem to succeed correctly.

import sketch
#some code

Can you help me figure out how to fix this error?

Deploy sketch on streamlit

Hi @alessandro_ciciarell, welcome to the forum! You’re encountering the error because the library you’re importing (sketch) imports another library (lambdaprompt) that uses async functions. But Streamlit runs in a separate thread that doesn’t have an event loop by default. To make it work, you’ll need to create an event loop and run the async functions inside it. The lambdaprompt library runs some async code during the import process itself. So you can try creating an event loop…
