go-npy

Read in .npy files produced by numpy into Go

Usage

import (
  npy "github.com/cquotient/go-npy"
  "github.com/gonum/matrix/mat64"
)
...

rows, cols, data, err := npy.Read("data/dense.py")
x := mat64.NewDense(int(rows), int(cols), data)

Caveats

• This is a hack, but it does work for us
• Only supports dense float64 matrices
• .npz files are not currently supported
• Assumes a single matrix in the file
