    :api_attr: Static Graph

    This function get parameters and optimizer information from program, and then get corresponding value from file.
    An exception will throw if shape or dtype of the parameters is not match.

    This function can also load model file saved with [ save_params, save_persistables, save_vars ].
    var_list can not be None  when load single model file
    ( filename is not None When save_params, save_persistables or save_vars is called ).

    Args:
        program(Program): The program will be loaded
        model_path(str): The file prefix store the program
        executor(Executor, optional): The executor used for initialize the parameter
                                      When startup program is not run.
        var_list(list|tuple, optional): The Tensor list/tuple to load single model file saved with
                                  [ save_params, save_persistables, save_vars ].
                                  Default: None

    Returns:
        None

    Examples:
        .. code-block:: pycon

            >>> import paddle
            >>> import paddle.static as static

            >>> paddle.enable_static()

            >>> x = static.data(name="x", shape=[10, 10], dtype='float32')
            >>> linear1 = paddle.nn.Linear(10, 10)
            >>> linear2 = paddle.nn.Linear(10, 10)
            >>> y = linear1(x)
            >>> z = linear2(y)
