How to call a cython library from pyo3?

[DennisZhangOiler]

I have a shared library that is built by python codes, how can i call it from rust?

I think you'd expect to interact with it through PyModule::import as if it were any other Python module; the fact that it's Cython should be treated as an implementation detail.

Thanks for replying, I may have some confusion here since I am not that familiar with python and cython, what I mean is I have a shared library built by command python3 -m Cython.Build.Cythonize -3b *.py;rm *.c;rm -rf build;, and in python it can be directly imported under the same path, but if i call importing in pyo3, it will report module not found, would you mind helping me with it?

I think https://pyo3.rs/v0.20.0/python_from_rust is a good starting point maybe.

What os are you using? Possibly #1896 (and similar discussion for macos) may get in the way.

Hi I am using ubuntu, it failed to import even I manually linked into the bin, I still can not figure out how to do it.
