Numexpr.utils: NumExpr defaulting to 8 threads

Hi i deployed streamlab webapp in anaconda docker container. I dont see the application its not showing in the browser.

even running gives similar issue with numexpr.utils

I got the same error

I am also getting the same error.Please anybody suggest how to fix this issue.

works fine on docker. im guessing its windows 10 thing.

Agreed, it looks like numpy brings some sort of add-on package with it.

I’ll try to take a look at this in a Windows environment today, see if I can reproduce it.

Best,
Randy

Unfortunately on a clean install of Python 3.9 and Streamlit 1.2, it didn’t happen for me. Are you using conda or a different way of installing Python?

The biggest question is where numexpr package comes from. It’s not a Streamlit requirement.

PS C:\Users\randy> pip install streamlit==1.2
