Thanks - in future I’ll check the repo for known issues :slight_smile:

After update to 1.12, start old project, get an error like this: File "C:\Python38\Scripts\streamlit.exe\__main__.py", line 4, in <module> ModuleNotFoundError: No moudle named "streamlit.cli" back to 1.11.1, this error disappear.

from streamlit.scriptrunner import add_script_run_ctx scriptrunner and add_script_run_ctx not found after updating to latest version. Could you please let me know if there are any changes made to the names?

@Shawn_Pereira Hmm ok that is indeed a bug. I’m on vacation right now, so can’t look into it for the next 2 weeks. Could you open an issue on Github and copy your text/screenshots in there? Then we have it tracked and the engineers can look into it. Fyi @mayabarnes for visibility.

@madhu_thatikonda [image] Accessing session_info in 1.12+ 🎈 Using Streamlit Hey @ennui , Thanks for surfacing this! The Server.get_current() method disappearing was indeed a consequence of a major refactor to the Streamlit internals that had its first changes appear in 1.…

Hi @Shawn_Pereira I’m afraid I don’t have a solution for it just yet. Did you try killing and restarting the apps after the update? Do you also run into the error when using the python -m streamlit run app.py format? Note: streamlit.cli has moved to streamlit.web.cli

Thanks @snehankekre for the quick response. Yes, I tried all that you mentioned; rebooted the machine too. Didn’t work. Uninstalled Streamlit and found that it could still invoke version 0.87. Promptly installed version 1.11 thereafter and everything was fine. I think I’ll skip 1.12 and move to th…
