numpy.split(ary, indices_or_sections, axis=0)[source] Split an array into multiple sub-arrays. Parameters: | ary : ndarrayArray to be divided into sub-arrays. indices_or_sections : int or 1-D arrayIf indices_or_sections is an integer, N, the array will be divided into N equal arrays along axis. If such a split is not possible, an error is raised. If indices_or_sections is a 1-D array of sorted integers, the entries indicate where along axisthe array is split. For example, [2, 3] would, for axis=0, result in
If an index exceeds the dimension of the array along axis, an empty sub-array is returned correspondingly. axis : int, optionalThe axis along which to split, default is 0. | Returns: | sub-arrays : list of ndarraysA list of sub-arrays. | Raises: | ValueErrorIf indices_or_sections is given as an integer, but a split does not result in equal division. |
