Not sure if this is really relevant to the original message, but here is my
opinion. I think that the numpy/scipy community would greatly benefit from a
platform enabling easy sharing of code written by users. This would provide a
database of solved problems, where people could dig without havin
Thanks for all the feedback (on the SSD too). For what concerns "biggus"
library, for working on larger-than-memory arrays, this is really interesting,
but unfortunately I don't have time to test it at the moment, I will try to
have a look at it in the future. I hope to see something like that i

My mistake, sorry, even if the help says so, it seems that this is not the case
in the actual code. Still, the problem with the size of the available data

This solution does not work for me since I have an offset before the data that
is not a multiple of the datatype (it's a header containing various stuff).
I'll at pytables.

Hi everybody, I hope this has not been discussed before, I couldn't find a
solution elsewhere.
I need to read some binary data, and I am using numpy.fromfile to do this.
Since the files are huge, and would make me run out of memory, I need to read

Dear all,
I would like to avoid the use of a boolean array (mask) in the following

mask = (A != 0.)
B = A[mask]
