Hey thank you for your response, yes I tried It didn’t work .

Can you try creating a new environment and installing Streamlit with conda-forge?

-In anaconda, click on environments.
-Click Create at the bottom.
-Choose an environment name.
-After it’s created, click the green play button and choose terminal.
-In the environment’s terminal, conda install -c conda-forge streamlit
-Confirm yes when prompted.
-Then streamlit hello when it finishes.

hey thanks buddy, that worked but one question I have new_environment for streamlit but that also gave me same error so I deleted that environment what is the piece exactly I missed ? could you tell.!

Sometimes a package just doesn’t install correctly and needs to be uninstalled and reinstalled. It’s been implied that conda-forge may be a bit more reliable than pip to install Streamlit, but in the end if streamlit hello doesn’t work it’s a sign that it didn’t install properly. So either uninstall and reinstall, or start a new environment. It’s probably why the documentation so strongly recommends using an environment instead of base.
