I am trying to install the package underthesea-core==1.0.4 in my Python 3.12 environment, but I am encountering an error during installation. The error message indicates that the package fails to build the wheel, and the issue is caused by the missing maturin module.
Here is the relevant error message I receive:
Using uv pip install.

The app works fine locally with Python 3.11, but when deployed on Streamlit Cloud, which is using Python 3.12, it fails. Is there any way to downgrade the Python version on Streamlit Cloud to 3.11 to avoid this issue?
