npy-ocaml

This contains a simple implementation of version 1.0 of the npy format spec. An opam package is available and can be installed via:

opam install npy

The main functions are:

• Writing ocaml bigarrays to npy files, these files can then be loaded from python using numpy.load.
• Reading ocaml bigarrays from npy files, the resulting bigarrays are mmapped to the file.
• Reading and writing npz files that could contain multiple arrays.
