The current release, version 0.82.0, contains fixes for two major bugs.
The first bug is a show-stopping segmentation fault under some versions
of Linux and arises from a variable type mismatch in calls to the numpy
api. The second bug causes bad spectral values at the Nyquist frequency

It caused problems with 2to3 for one thing because it was getting imported

I want to subclass ndarray to create a class for image and volume data, and
when referencing a file I'd like to have it load the data only when accessed.
That way the class can be used to quickly set and manipulate header values, and
won't load data unless necessary. What is the best way to

Similar to what Matthew said, I often find that it's cleaner to make a
seperate class with a data (or somesuch) property that lazily loads the
numpy array.
For example, something like:
class DataFormat(object):
def __init__(self, filename):
self.filename = filename
for key,
For lazy data loading I use memory-mapped array (numpy.memmap): I use it to
process multi-image files that are much larger than the available RAM.
