Crate numpy[][src]

Expand description

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 numpy::{ToPyArray, PyArray};
fn main() {
    pyo3::Python::with_gil(|py| {
        let py_array = array![[1i64, 2], [3, 4]].to_pyarray(py);
        assert_eq!(
            py_array.readonly().as_array(),
            array![[1i64, 2], [3, 4]]
        );
    })
}

Modules

Safe interface for NumPy ndarray

Defines conversion traits between rust types and numpy data types.

Low-Level bindings for NumPy C API.

Wrapper of Array Iterator API.

Macros

Create an Array with one, two or three dimensions.

Return the Einstein summation convention of given tensors.

Create a PyArray with one, two or three dimensions. This macro is backed by ndarray::array.

Structs

Represents that the array is not contiguous.

Binding of numpy.dtype.

Readonly reference of PyArray.

Represents that shapes of the given arrays don’t match.

Enums

Represents numpy data type.

Traits

Represents that a type can be an element of PyArray.

Iterator mode for single iterator

Functions
