Hi, I am having some problems with win64 with all my tests failing. I installed amd64 Python from Python.org and numpy and scipy from http://www.lfd.uci.edu/~gohlke/pythonlibs/ I noticed that on windows sys.maxint is the 32bit value (2147483647 ___

[Numpy-discussion] subtle behavior when subtracting sub-arrays

2010-07-05 Thread Steve Schmerler
Hi I stumbled upon some numpy behavior which I was not aware of. Say I have an array of shape (2,2,3) and want to subtract the sub-array a[...,0] of shape (2,2) from each a[...,i], i=0,1,2 . ## ok ## In [1]: a=arange(2*2*3).reshape(2,2,3) # Copy the array to be subtracted. In

[Numpy-discussion] BOF notes: Fernando's proposal: NumPy ndarray with named axes

2010-07-05 Thread Jonathan March
Fernando Perez proposed a NumPy enhancement, an ndarray with named axes, prototyped as DataArray by him, Mike Trumpis, Jonathan Taylor, Matthew Brett, Kilian Koepsell and Stefan van der Walt. At SciPy 2010 on July 1, Fernando convened a BOF (Birds of a Feather) discussion of this proposal. The
