tf.contrib.layers.stack

Builds a stack of layers by applying layer repeatedly using stack_args.

tf.contrib.layers.stack(
    inputs, layer, stack_args, **kwargs
)

stack allows you to repeatedly apply the same operation with different arguments stack_args[i]. For each application of the layer, stack creates a new scope appended with an increasing number. For example:

y = stack(x, fully_connected, [32, 64, 128], scope='fc')
# It is equivalent to:

x = fully_connected(x, 32, scope='fc/fc_1')
x = fully_connected(x, 64, scope='fc/fc_2')
y = fully_connected(x, 128, scope='fc/fc_3')

If the scope argument is not given in kwargs, it is set to layer.__name__, or layer.func.__name__ (for functools.partial objects). If neither __name__ nor func.__name__ is available, the layers are called with scope='stack'.
