Summary

Streamlit 1.23.0, released today, breaks if the typing-extensions package is version 3.10.0.2.

Manually upgrading the typing-extensions package to a version >= 4.0.0 fixes this, as does downgrading to Streamlit 1.22.0.

Suggested fix: specify typing_extensions>=4.0.0 in the requirements file.

Steps To Reproduce

pip install typing_extensions==3.10.0.2
pip install streamlit==1.23.0
streamlit hello

Current Behavior

Running streamlit hello or streamlit run myscript.py raises the following exception with Streamlit 1.23.0 and typing_extensions 3.10.0.2:

  File "/opt/conda/lib/python3.9/site-packages/streamlit/elements/lib/column_types.py", line 20, in <module>
    from typing_extensions import Literal, NotRequired, TypeAlias, TypedDict
ImportError: cannot import name 'NotRequired' from 'typing_extensions' (/opt/conda/lib/python3.9/site-packages/typing_extensions.py)

The full traceback is here.
