How far away is maskedarray from being able to replace numpy.ma?
So far, it does everything that numpy.core.ma does, with I believe more
flexibility and some additional features (hard/soft mask, easy
subclassing...). Personally, I stopped using numpy.core.ma
Hi all,
I need to know the libraries (BLAS and LAPACK) which numpy has been linked
to, when I compiled it.
I can't remember which ones I used (ATLAS, MKL, etc...)...
Is there an easy way to find it out?
Thanks in advance,

Hi,
This can lead to surprising bugs in code that either explicitly
expects it to behave like python's max() or implicitly expects that by
doing from numpy import max.
my solution is to never use numpy.max. For arrays, I always use the method
call (somearray.max()). For everything else

Can someone please confirm if the following is the expected behavior
of numpy ndarrays of dtype=object, i.e. object arrays. I suspect it
might be a bug.
In the Python shell dump below, shouldn't the dtype of oa2[0] and
oa2[1] be 'int32' as is the case for oa1[0] and oa1[1] ?

Well, all the credits should go to Paul Dubois, the original author of
numpy.core.ma, and the scores of people

But I agree: switching may have some subtle consequences in
matplotlib (nothing that can't be quickly fiexed, however).
All examples in backend_driver.py test seem to run fine (+ others I added
that contained masked arrays).

It's expected. The array() function has to make some guesses as to what you
meant when you pass it a sequence of

sum(sequence, start=0)
The problem here is that Numeric had sum before Python had sum. So,
there is a legacy issue.
As you can tell, there are limits to my concern of shadowing builtins.
That's what

David, I wouldn't speak about compatibility, just about bugs: the problem was
in the implementation of .max() w/ maskedarray. The origin of the problem was
(is still) in umath.maximum.reduce that doesn't accept axis=None, so a numpy
problem ;). But I agree:
