summary: "Forwards the value of an available tensor from `inputs` to `output`."
description: <<END
`Merge` waits for at least one of the tensors in `inputs` to become available.
It is usually combined with `Switch` to implement branching.
`Merge` forwards the first tensor for become available to `output`, and sets
`value_index` to its index in `inputs`.
