Make your scalar a Variable containing a 1D tensor, and use the expand_as function. … WebIf you use a variable like a tensor in operations, you will usually operate on the backing tensor. Creating new variables from existing variables duplicates the backing tensors. Two variables will not share the same memory. a = tf.Variable([2.0, 3.0]) # Create b based on the value of a b = tf.Variable(a) a.assign([5, 6]) # a and b are different
