Args: chunk_size (int or tuple(int, int), optional): Chunk size in (y, x) directions, or the same size in both directions if only one is specified. Cannot be negative. chunk_count (int or tuple(int, int), optional): Chunk count in (y, x) directions, or the same count in both directions if only one is specified. If less than 1, set to 1. total_chunk_count (int, optional): Total number of chunks. If less than 1, set to 1. ny (int): Number of grid points in y-direction. nx (int): Number of grid points in x-direction. Return: tuple(int, int): Chunk sizes (y_chunk_size, x_chunk_size). Note: Zero or one of ``chunk_size``, ``chunk_count`` and ``total_chunk_count`` should be specified.
