A list of Tensor objects. A list of input tensors.
Tout

f
A function decorated with @Defun.
A function that takes 'args', a list of tensors, and returns 'output',
another list of tensors. Input and output types are specified by 'Tin'
and 'Tout'. The function body of f will be placed and partitioned across
devices, setting this op apart from the regular Call op. This op is
stateful.
