Yep, I'm trying to construct dtype2 programmaticaly and was hoping for some
function giving me a canonical expression of the dtype. I've started playing
with fields but it's just a bit harder than I though (lot of different cases
and recursion).
Thanks for the answer.

Hello,
I have an array that I know will need to grow to X elements. However, I
will need to work with it before it's completely filled. I see two ways
of doing this:
bigarray = np.empty(X)
current_size = 0
for i in something:
buf = produce_data(i)

what sort of work with it do you mean? -- resize() is dangerous if
there are any other views
Hi,
I have 2D array, let's say: `np.random.random((100,100))` and I want
to do simple manipulation on each point neighbors, like divide their
values by 3.
So for each array value, x, and it neighbors n:
n n nn/3 n/3 n/3
n x n - n/3 x n/3
n n nn/3 n/3 n/3
I searched a bit, and found

Dear all,
I found here

that to use* numpy.ma.testutils.assert_almost_equal* for masked array
assertion, but I cannot find the np.ma.testutils
Thanks. I tried again, it works.
