Write a python pkg by pyo3. But failed to extract rust struct from calling python function in another crate

[Poseidon-fan]

Put simply, I write a python pkg by rust:

#[pyclass]
#[derive(Clone, Debug)]
pub struct Resp {
    pub msg: String,
}

and run maturin develop to install it in current venv.

In another rust binary crate, I call a python function which returns a Resp struct. When I try to extract this python object back to rust, it throws err:

TypeError: 'Resp' object cannot be converted to 'Resp'

Currently #[pyclass]es cant be shared between different crates in this way. Each crate will create its own Python type object the the pyclass, making them distinct from Pythons perspective. See #1444 for more details.
