Hi all,
I'm trying to import a 16-bit tiff image into a numpy array. I have
found, using google, suggestions to do the following:
After starting with:
i = Image.open('16bitGreyscaleImage.tif')
Stéfan van der Walt suggested:
a = np.array(i.getdata()).reshape(i.size) # a 1d numpy array

I think this is also true in the machine learning community.

The interest is in information theory, where quantities are

Hi Nadav,
Thank you very much. My next question;
How can I save lines_list to a file with the following
so called small field form
I'm just about to embark on a long-term research project and was
planning to use numpy.random to generate stimuli for our experiments.
We plan to store only the parameters and RandomState seed for each
stimulus and I'm concerned about stability of the API in the long
term: will the parameters and r
A correction:
lines_list = [cc[i:i+8] for i in range(1, len(cc), 8)]

Dear Robert,
indeed, this is the difference ! Thanks ! Seeding numpy with 4357
gives identical sequences...

Hi,
I might be doing something stupid so I thought i'd check here before
filing a bug report.
Firstly:
In [8]: np.__version__
Out[8]: '1.3.0.dev5883'
Basically, pickling an element from a recarray seems to break silently:
In [1]: import numpy as np
In [2]: dtype = [('r','f4'),('g','f4'),('b','f4
