Function map_fn

map on the list of tensors unpacked from `elems` on dimension 0. The simplest version of `map_fn` repeatedly applies the callable `fn` to a sequence of elements from first to last. The elements are made of the tensors unpacked from `elems`. `dtype` is the data type of the return value of `f

(fn, elems, dtype=None, parallel_iterations=10, back_prop=True,
           swap_memory=False, infer_shape=True, name=None)
