For this purpose, we will directly multiply the numpy array with the specific scalar value and then we will use the numpy.dstack() method.The numpy.dstack() method is used to stack arrays in sequence depth-wise (along the third axis). It takes a parameter called tup which is the ...

I was wondering if re-arranging/narrower scoping of theerrstatecontext helps. I suspect it might work, but only by replacing non-finite values inabs(y)with 0 or so, so not sure it is a good path. (something to explorer if we care about theerrstatehonoring only!) ...
Describe the issue: Executing multiple (more than 1) np.multiply calls with a sufficiently big dataset causes a job in multiprocessing to hang. Reproduce the code example: from multiprocessing import Pool, cpu_count import numpy as np fr...
