I have a very large size multi-dimensional numpy array. I want to save it so as to save time. I am using pickle for that purpose.

pickle.dump( arrTotal, open( "arrTotal.p", "wb" ) )

But I am getting Memory Error when I try to save it this way. Is there some other way I can do it without causing memory error?

Pickle is almost certainly not an ideal format for saving numpy data...

I'd recommend trying something like numpy.savez, numpy.save or numpy.savez_compressed.
