WebFrom Cython 3, accessing attributes like # ".shape" on a typed Numpy array use this API. Therefore we recommend # always calling "import_array" whenever you "cimport numpy" np.import_array() # We now need to fix a datatype for our arrays. I've used the variable # DTYPE for this, which is assigned to the usual NumPy runtime # type info object. WebIf a function’s Python counterpart returns multiple values, then the function returns its outputs via pointers in the final arguments.
