    Args:
        data_format: string, either `"channels_last"` or `"channels_first"`.
            The ordering of the dimensions in the inputs. `"channels_last"`
            corresponds to inputs with shape `(batch, height, width, channels)`
            while `"channels_first"` corresponds to inputs with shape
            `(batch, features, height, weight)`. It defaults to the
            `image_data_format` value found in your Keras config file at
            `~/.keras/keras.json`. If you never set it, then it will be
            `"channels_last"`.
        keepdims: A boolean, whether to keep the temporal dimension or not.
            If `keepdims` is `False` (default), the rank of the tensor is
            reduced for spatial dimensions. If `keepdims` is `True`, the
            spatial dimension are retained with length 1.
            The behavior is the same as for `tf.reduce_mean` or `np.mean`.

    Input shape:

    - If `data_format='channels_last'`:
        4D tensor with shape:
        `(batch_size, height, width, channels)`
    - If `data_format='channels_first'`:
        4D tensor with shape:
        `(batch_size, channels, height, width)`

    Output shape:

    - If `keepdims=False`:
        2D tensor with shape `(batch_size, channels)`.
    - If `keepdims=True`:
        - If `data_format="channels_last"`:
            4D tensor with shape `(batch_size, 1, 1, channels)`
        - If `data_format="channels_first"`:
            4D tensor with shape `(batch_size, channels, 1, 1)`

    Example:

    >>> x = np.random.rand(2, 4, 5, 3)
    >>> y = keras.layers.GlobalMaxPooling2D()(x)
    >>> y.shape
    (2, 3)
