Hi all,
At the prodding [1] of Sebastian, I’m starting a discussion on the decision to
deprecate np.{bool,float,int}. This deprecation broke our prerelease testing in
scikit-image (which, hooray for rcs!), and resulted in a large amount of code
churn to fix [2].
To be honest, I do think *some* sort of deprecation is needed, because for the
longest time I thought that np.float was what np.float_ actually is. I think it
would be worthwhile to move to *that*, though it’s an even more invasive
deprecation than the currently proposed one. Writing `x = np.zeros(5,
dtype=int)` is somewhat magical, because someone with a strict typing mindset
(there’s an increasing number!) might expect that this is an array of pointers
to Python ints. This is why I’ve always preferred to write `dtype=np.int`,
resulting in the current code churn.
I don’t know what the best answer is, just sparking the discussion Sebastian
wants to see. ;) For skimage we’ve already merged a fix (even if it is one of
dubious quality, as Stéfan points out [3] ;), so I don’t have too much stake in
the outcome.
Juan.
