multiple definition of `PyInit__internal'

[andygrove]

I am trying to build a maturin project (pyballista) that depends on another maturin project (datafusion). As soon as I reference a struct from the other project I run into this build error:

multiple definition of `PyInit__internal'

They do both have the same _internal function defined (but in different namespaces).

#[pymodule]
fn _internal(py: Python, m: &PyModule) -> PyResult<()> {
}

Any help with understanding this issue would be appreciated.

I found the solution - I had assumed that this method had to be named _internal by convention but it can be any name
