tensorflow 一些使用技巧

1. 多个变量在session中run:

import tensorflow as tf

x = [[1,2,3],
[1,2,3]]

xx = tf.cast(x,tf.float32)

mean_all = tf.reduce_mean(xx, keep_dims=False)
mean_0 = tf.reduce_mean(xx, axis=0, keep_dims=False)
mean_1 = tf.reduce_mean(xx, axis=1, keep_dims=False)


with tf.Session() as sess:

m_a,m_0,m_1 = sess.run([mean_all, mean_0, mean_1])　　#多个变量在session中run
