[Numpy-discussion] np.dot and array order

2011-11-30 Thread josef . pktd
np.__version__ '1.5.1' official win32 installer (playing with ipython for once) I thought np.dot is Lapack based and favors fortran order, but if the second array is fortran ordered, then dot takes twice as long. The order of the first array seems irrelevant (or maybe just with my shapes, in

[Numpy-discussion] loop through arrays and find numpy maximum

2011-11-30 Thread questions anon
I would like to calculate the max and min of many netcdf files. I know how to create one big array and then concatenate and find the numpy.max but when I run this on 1000's of arrays I have a memory error. What I would prefer is to loop through the arrays and produce the maximum without having the

[Numpy-discussion] ignore NAN in numpy.true_divide()

2011-11-30 Thread questions anon
I am trying to calculate the mean across many netcdf files. I cannot use numpy.mean because there are too many files to concatenate and I end up with a memory error. I have enabled the below code to do what I need but I have a few nan values in some of my arrays. Is there a way to ignore these some

My suggestion is: don't. It's easier to script runs if you read parameters from the command line. I recommend argparse. Giovanni Plantageneto wrote: > Dear all, > I have a simple question. I would like to have all the parameters of a > model written in a configuration file (text), and I would li
