tensorflow 打印内存中的变量方法

法一：

循环打印

模板

for (x, y) in zip(tf.global_variables(), sess.run(tf.global_variables())):
 print '\n', x, y

实例

# coding=utf-8

import tensorflow as tf

def func(in_put, layer_name, is_training=True):
 with tf.variable_scope(layer_name, reuse=tf.AUTO_REUSE):
  bn = tf.contrib.layers.batch_norm(inputs=in_put,
           decay=0.9,
           is_training=is_training,
           updates_collections=None)
 return bn

def main():

 with tf.Graph().as_default():
  # input_x
  input_x = tf.placeholder(dtype=tf.float32, shape=[1, 4, 4, 1])
  import numpy as np
  i_p = np.random.uniform(low=0, high=255, size=[1, 4, 4, 1])
  # outputs
  output = func(input_x, 'my', is_training=True)
  with tf.Session() as sess:
   sess.run(tf.global_variables_initializer())
   t = sess.run(output, feed_dict={input_x:i_p})

   # 法一： 循环打印
   for (x, y) in zip(tf.global_variables(), sess.run(tf.global_variables())):
    print '\n', x, y

if __name__ == "__main__":
 main()

法二：

指定变量名打印

模板

print 'my/BatchNorm/beta:0', (sess.run('my/BatchNorm/beta:0'))

实例

 return bn
