Crate numpy

rust-numpy provides Rust interfaces for NumPy C APIs, especially for ndarray class.

It uses pyo3 for rust bindings to cpython, and uses ndarray for rust side matrix library.

For numpy dependency, it calls import numpy.core internally. So you just need numpy installed by pip install numpy or other ways in your python environment. You can use both system environment and virtualenv.

This library loads numpy module automatically. So if numpy is not installed, it simply panics, instead of returing a result.

Example

#[macro_use]
extern crate ndarray;
use pyo3::prelude::Python;
use numpy::{ToPyArray, PyArray};
fn main() {
    let gil = Python::acquire_gil();
    let py = gil.python();
    let py_array = array![[1i64, 2], [3, 4]].to_pyarray(py);
    assert_eq!(
        py_array.readonly().as_array(),
        array![[1i64, 2], [3, 4]]
    );
}
