// Package op defines functions for adding TensorFlow operations to a Graph.
//
// Functions for adding an operation to a graph take a Scope object as the
// first argument. The Scope object encapsulates a graph and a set of
// properties (such as a name prefix) for all operations being added
// to the graph.
//
// WARNING: The API in this package has not been finalized and can
// change without notice.
