Hi, i am a fresh man here and i’ve met some trouble when i finish installing streamlit through anaconda. I input “streamlit hello” in cmd and the web opened without demo on the sidebar. Can anyone give me a hand? Thanks a lot!

What Python and Streamlit versions are you on?
I get a correct hello app with Python 3.10.8 and Streamlit 1.15.2.
I get the same, not quite right one with Python and Streamlit 1.11.0.

I met it with Python 3.10.8 and Streamlit 1.11.0

Can you upgrade Streamlit and see if that resolves it?

From your terminal (with your activated environment if you used one):
conda update -c conda-forge streamlit -y

Ok, i’ll try it. Thanks very much!
