Folks,
I'm running into the following problem with putmask on take.

x = N.arange(12.)
m = [1, 0, 0, 0, 0, 0, 1, 0, 0, 1, 0, 1]
i = N.nonzero (m)[0]
w = N.array([-1, -2, -3, -4.])
x.putmask(w,m)
You can also use

I would like to read files 2Gbyte. From earlier posting
I believed it should be possible with python 2.5.
I am getting MemoryError when trying to read a file larger
than 2Gb.
I am using python2.5 and numpy1.0rc1.
Any solution to the problem?

Do you also have a 64-bit processor? Just checking since you didn't mention it.

According to the putmask docstring:
a.putmask(values, mask) sets a.flat[n] = v[n] for each n where
mask.flat[n] is true. v can be scalar.
This would mean that 'w' is not of the right length.

What about using it for .sum() by default? What is the speed hit anyway?
In any case, having it available would be nice.

I have seen the set_printoptions() functions, but it doesn't really

Can this be done? How?

You can write a function that formats arrays how you like
You can write a function that formats arrays how you like them and then tell
ndarray to use it for __str__ or __repr__ using numpy.set_string_function().
That seems to be a little low level for most users. Would it be hard
to have the possibility of specifying a format string?
