tf.scan(fn, elems, initializer=None, parallel_iterations=10, back_prop=True, swap_memory=False, infer_shape=True, name=None) scan on the list of tensors unpacked from elems on dimension 0. The simplest version of scan repeatedly applies the callable fn to a sequence of elements from first to last. The elements are made of the tensors unpacked from elems on dimension 0. The callable fn takes two tensors as arguments. The first argument is the accumulated value computed from the preceding invoca

tf.scalar_mul(scalar, x) Multiplies a scalar times a Tensor or IndexedSlices object. Intended for use in gradient code which might deal with IndexedSlices objects, which are easy to multiply by a scalar but more expensive to multiply with arbitrary tensors. Args: scalar: A 0-D scalar Tensor. Must have known shape. x: A Tensor or IndexedSlices to be scaled. Returns: scalar * x of the same type (Tensor or IndexedSlices) as x. Raises: ValueError: if scalar is not a 0-D scalar.

tf.round(x, name=None) Rounds the values of a tensor to the nearest integer, element-wise. For example: # 'a' is [0.9, 2.5, 2.3, -4.4] tf.round(a) ==> [ 1.0, 3.0, 2.0, -4.0 ] Args: x: A Tensor of type float32 or float64. name: A name for the operation (optional). Returns: A Tensor of same shape and type as x.
