Hi Guys,
Great toolbox, keep up the good work. I have a question about speeding up the
Searchlight algorithm.
When I run the algorithm, it tends to start off quickly and then progressively
slow down to a snail's pace. Windows reports that pythonw.exe, at it's peak, is
only consuming ~250mbs of memory (despite the availibility of up to 14gbs of
RAM and a massive pagefile).
My question is, is there some way to increase the memory being used and thus
speed up the process? Windows limits 32bit programs to 2gbs and provides memory
upon request and there does not seem to be any reason that Windows would refuse
python any memory?
Also, it seems counterintuitive to me that Searchlight would start off quick
and then slow down, surely each voxel should take the same amount of time? Can
you think of anything that might be causing this?
OS: Windows Vista Business 64bit (running Python in 32bit mode)
Xeon E5440 processor
16gb RAM
#dataset is the accompanying Haxby study
#nifti images and mask load fine
clf = LinearNuSVMC(nu=0.1)
cv = CrossValidatedTransferError(TransferError(clf),
NFoldSplitter())
sl = Searchlight(cv, radius=3)
sl_map = sl(dataset)
Regards,
Dan
