WebWhen implementing a new algorithm is thus recommended to start implementing it in Python using Numpy and Scipy by taking care of avoiding looping code using the vectorized idioms of those libraries. In practice this means trying to replace any nested for loops by calls to equivalent Numpy array methods. WebNumPy arrays support this interface, as do Cython arrays. The “nearly all” is because the Python buffer interface allows the elements in the data array to themselves be pointers; Cython memoryviews do not yet support this. Memory layout ¶ The buffer interface allows objects to identify the underlying memory in a variety of ways.
