tf.keras.layers.AveragePooling3D(
    pool_size=(2, 2, 2), strides=None, padding='valid', data_format=None, **kwargs
)

Arguments
pool_size	tuple of 3 integers, factors by which to downscale (dim1, dim2, dim3).(2, 2, 2) will halve the size of the 3D input in each dimension.
strides	tuple of 3 integers, or None. Strides values.
padding	One of "valid" or "same" (case-insensitive).
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, spatial_dim1, spatial_dim2, spatial_dim3, channels)while channels_first corresponds to inputs with shape(batch, channels, spatial_dim1, spatial_dim2, spatial_dim3). 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".

If data_format='channels_last': 5D tensor with shape:(batch_size, spatial_dim1, spatial_dim2, spatial_dim3, channels)
If data_format='channels_first': 5D tensor with shape:(batch_size, channels, spatial_dim1, spatial_dim2, spatial_dim3)

If data_format='channels_last': 5D tensor with shape:(batch_size, pooled_dim1, pooled_dim2, pooled_dim3, channels)
If data_format='channels_first': 5D tensor with shape:(batch_size, channels, pooled_dim1, pooled_dim2, pooled_dim3)
