Global average pooling operation for spatial data.
tf.keras.layers.GlobalAveragePooling2D( data_format=None, **kwargs )
input_shape = (2, 4, 5, 3) x = tf.random.normal(input_shape) y = tf.keras.layers.GlobalAveragePooling2D()(x) print(y.shape) (2, 3)
Arguments | |
---|---|
data_format | A string, one of channels_last (default) 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, channels, height, width) . 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". |
data_format='channels_last'
: 4D tensor with shape (batch_size, rows, cols, channels)
.data_format='channels_first'
: 4D tensor with shape (batch_size, channels, rows, cols)
.2D tensor with shape (batch_size, channels)
