Nettet24. mai 2024 · The reason is that using pre-defined Numpy methods takes advantage of the underlying optimized C code that Numpy uses. Thus, whenever you want to define a customized vectorized function, consider whether there is any pre-defined method that can do the same job first; if not, you are safe to register your own vectorized function. Nettetclass numpy.vectorize(pyfunc=np._NoValue, otypes=None, doc=None, excluded=None, cache=False, signature=None) [source] #. Returns an object that acts like pyfunc, but takes arrays as input.
