Deprecated! Use for example crate ndarray-npy for a much more complete implementation.
A simple serialization of ndarray arrays of simple types (f32
, f64
) into
NumPy's .npy
format.
Files produced this way can be loaded with numpy.load
.
extern crate ndarray;
extern crate ndarray_npy;
use ndarray::prelude::*;
use std::io;
fn main() {
let arr: Array2<f64> = Array2::zeros((3, 4));
let stdout = io::stdout();
let mut handle = stdout.lock();
ndarray_npy::write(&mut handle, &arr).unwrap();
}
For a more generic serialization and deserialization, see crate npy.
