Can we retire numerix?

Development matplotlib-devel
1

Hi all,

I just ran into an issue with py2exe -- my app failed because various numpy sub-packages weren't included. However, I wasn't using them. But it failed because numerix imports them, and they weren't included because it imports them with __import__

Anyway, I can work around this, but it made me wonder: is it time to retire numerix? We all should be using numpy anyway.

note that the docstring is out of date, too:

"""
1. The value of numerix in matplotlibrc: either Numeric or numarray

2. If none of the above is done, the default array package is Numeric.
    Because the matplotlibrc always provides *some* value for numerix
    (it has it's own system of default values), this default is most
    likely never used.

To summarize: the commandline is examined first, the rc file second,
and the default array package is Numeric.

Why was numerix getting imported? Is this inherent in py2exe--that it imports all subpackages of a base, if you use that base (matplotlib)?

Numerix is there only for the convenience of anyone who has code that depends on it; it is completely unused in matplotlib itself. I would be happy get it out of matplotlib, or phase it out if necessary. I don't think it should be left there forever.

Good question -- I just figured MPL was doing it!

nope -- it imports the regular old python way --just with a different sys.path

I'll poke into it a bit more, now that I know it shouldn't be doing it.

That's what I was hoping.

I agree.

I think it can be removed. It lives on the maintenance branch 0.91.

Good point. I am in the process of removing it from the trunk. I should be doing this slightly differently, with a single commit, but I got ahead of myself, so it will take more than one. Sorry.

It has been purged from the svn trunk. Now, if you can run your app after building from svn, it should become obvious where the numerix import was coming from, assuming it was in your app or in some package it imports.

Thanks. Has it been deprecated somehow? I don't want folks' code to break too fast!

Well, I'm not set up to build on Windows...

Found it: it was wxmpl. I'm going to send a patch to Ken.

No, I guess I was in a dangerous mood--I just ripped it out. I could put it back with a deprecation if necessary--is it? The only nod to deprecation at present is that a matplotlibrc file with a numerix entry will trigger a warning instead of bombing.

It is still in the 0.98.5 maintenance branch, which I presume will be the source of the next release. One option would be to put a deprecation warning there, but leave the trunk as-is.

What we probably *should* have done was to put a deprecation warning in back when 0.98 was first released.

Ken,

I've found Numerix used in wxmpl, but it's been deprecated, so I've replaced all the calls with direct numpy calls. However, I can't pretend that I've tested well at all -- all I know is that it's working for me. In particular, I haven't tested plotit beyond making sure it complies.

I've enclosed a zip archive with my modifications. If you have it in SVN somewhere I could give you a diff -- just let me know if I can help further.

Also, I see this a lot in your plotit code:

if not isinstance(x, (np.ndarray, np.ma.masked_array)):

(though you had Numerix equivalent)

What I like to do instead is call:

try:
     x = asarray(x, dtype=np.float)
except ValueError:
     raise your error here...

(and maybe a reshape call, too, to make sure it can be converted into that shape)

I usually don't care if I'm getting an array, as long as it can be turned into one...

If you do want to check the type, np.ma is a subclass of ndarray, so:

isinstance(x, np.ndarray)

should do it. That's what I've put in the code for now.

I have restored a stripped-down numpy-only version of numerix, with a prominent deprecation warning.
