有一个函数tf.Graph.get_tensor_by_name（）。例如：
import tensorflow as tfc = tf.constant([[1.0, 2.0], [3.0, 4.0]])d = tf.constant([[1.0, 1.0], [0.0, 1.0]])e = tf.matmul(c, d, name='example')with tf.Session() as sess: test = sess.run(e) print e.name #example:0 test = tf.get_default_graph().get_tensor_by_name("example:0") print test #Tensor("example:0", shape=(2, 2), dtype=float32)
