Hi all, the doc http://docs.scipy.org/doc/numpy/reference/generated/numpy.load.html contains the following example: Store compressed data to disk, and load it again:

...

...

np.savez('/tmp/123.npz', a=np.array([[1, 2, 3], [4, 5, 6]]), b=np.array([1, 2])) data = np.load('/tmp/123.npy')

However http://docs.scipy.org/doc/numpy/reference/generated/numpy.savez.html says: numpy.savez(file, *args, **kwds)¶ Save several arrays into a single file in uncompressed .npz format. Moreover, this last page points to an undocumented numpy.savez_compressed function, which is also non-existent in my version of numpy (1.5.1-2ubuntu2). That's quite confusing.

From the following thread, it seems the arrays are stored uncompressed in a zipfile. http://article.gmane.org/gmane.comp.python.numeric.general/38378

Can somebody confirm that/fix the docs? Cheers -- Sébastien
