打印输出张量的值的方法

import tensorflow as tfzeros = tf.zeros([3,3])# 方法1
with tf.Session():print(zeros.eval())# 方法2
sess = tf.Session()
print(sess.run(zeros))

打印输出tensor变量的值的方法

import tensorflow as tfones=tf.Variable(tf.ones([3,3]))# 方法1 InteractiveSession + initializer
inter_sess=tf.InteractiveSession()
ones.initializer.run()
print(inter_sess.run(ones))# 方法2
inter_sess=tf.InteractiveSession()
tf.global_variables_initializer().run()
print(inter_sess.run(ones))# 方法3 Session + global_variables_initializer
sess=tf.Session()
sess.run(tf.global_variables_initializer())
print(sess.run(ones))# 方法4 with Session + global_variables_initializer
with tf.Session() as sess:sess.run(tf.global_variables_initializer())print(sess.run(ones))
