Hi @madhukarjadhav736,

I've reproduced this issue and narrowed it down to python 3.13 with any version of Streamlit.

Are you able to use python 3.12.9 as a mitigation?

Anu update on this?

[sfc-gh-lwilby]

@madhukarjadhav736 when I looked into this in February, I found the error is because of this line in the docstring of the package you are using that has an emoji. If I remember correctly, there was a change in Python that makes this no longer work with the Streamlit script runner when we need to call exec on your script.

Do you know the maintainer of this library? We thought the simplest solution would be to remove that emoji.

[madhukarjadhav736]

Good, thanks , will try doing that.
