tensorflow实现数字的自加1

import tensorflow as tf

aa=tf.Variable(0)
bb=tf.add(aa,1)
update=tf.assign(aa,bb)
init=tf.global_variables_initializer()
with tf.Session() as sess:
    sess.run(init)
    print(sess.run(aa))   #打印aa的初始值
    for ii in range(5):
        sess.run(update)  #给aa自加1
        print(sess.run(aa))  #打印aa
