[Tutor] np.array operation memoryerror

[f.hochwart at gmx.de]

Hello,



for my masterthesis I have to compute e.g. np.arrays with following
settings:



MemoryError: Unable to allocate 7.15 TiB for an array with shape (991600,
991600) and data type float64



    A =  sparse.bsr_matrix(C1 * (sparse.bsr_matrix(np.eye(dA, k = dR)) -2 *
sparse.bsr_matrix(np.eye(dA)) + sparse.bsr_matrix(np.eye(dA, k = -dR))))



Even if I use sparse function or np.float32 the memoryerror still appears. I
searched in different forums and havent found a proper solution yet.



The main question is, how can I compute big np.arrays which extend my
memory.



Best Regards,

Florian Hochwart
