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 theimage_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.

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 theimage_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.GlobalAveragePooling2D()(x) y.shape (2, 3)

Attributes
input	Retrieves the input tensor(s) of a symbolic operation.Only returns the tensor(s) corresponding to the _first time_the operation was called.
output	Retrieves the output tensor(s) of a layer.Only returns the tensor(s) corresponding to the _first time_the operation was called.

Methods

`from_config`

View source

@classmethod from_config( config )

Creates a layer from its config.

This method is the reverse of get_config, capable of instantiating the same layer from the config dictionary. It does not handle layer connectivity (handled by Network), nor weights (handled by set_weights).

Args
config	A Python dictionary, typically the output of get_config.

Returns
A layer instance.
