Python/Numpy MemoryError

Question

Basically, I am getting a memory error in python when trying to perform an algebraic operation on a numpy matrix. The variable u, is a large matrix of double (i

Answer 1

Another tip I have found to avoid memory errors is to manually control garbage collection. When objects are deleted or go our of scope, the memory used for these variables isn't freed up until a garbage collection is performed. I have found with some of my code using large numpy arrays that I get a MemoryError, but that I can avoid this if I insert calls to gc.collect() at appropriate places.

You should only look into this option if using "op=" style operators etc doesn't solve your problem as it's probably not the best coding practice to have gc.collect() calls everywhere.
