ValueError: signal only works in main thread

🎈 Using Streamlit

Hi, I’m getting this ValueError when I run my app. It was running fine just a couple weeks ago, so I’m not sure what changed. I didn’t edit anything within the app, but perhaps some component updated?

ValueError: signal only works in main thread

Traceback:

Hi @asor12 -

Can you provide a code snippet that shows what you are doing? Ideally, a GitHub repo so we can run the code ourselves?

Best,
Randy
