tensorflow: variable的值与variable.read_value()的值区别详解

# coding=utf-8import tensorflow as tf# Create a variable.w = tf.Variable(initial_value=10., dtype=tf.float32)sess = tf.InteractiveSession()sess.run(tf.global_variables_initializer())print '/nw.read_value() :/n', w.read_value(), '/n', w.read_value().eval()print '/nw :/n', w, '/n', w.eval()sess.close()

w.read_value() :Tensor("read:0", shape=(), dtype=float32) 10.0w :<tf.Variable 'Variable:0' shape=() dtype=float32_ref> 10.0
