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
