cf.FREE_MEMORY_FACTOR

cf.FREE_MEMORY_FACTOR(*args)

The free memory factor must be a sensible value between zero and one. If no arguments are passed the existing free memory factor is returned.

Parameters:

free_memory_factor: float

The fraction of memory kept free as a temporary workspace.

Returns:

float

The previous value of the free memory factor.
