在test.py中可以通过如下代码直接生成带weight的pb文件，也可以通过tf官方的freeze_graph.py将ckpt转为pb文件。
constant_graph = graph_util.convert_variables_to_constants(sess, sess.graph_def,['net_loss/inference/encode/conv_output/conv_output'])
with tf.gfile.FastGFile('net_model.pb', mode='wb') as f:
f.write(constant_graph.SerializeToString())
tf1.0中通过带weight的pb文件与get_tensor_by_name函数可以获取每一层的输出

for i in transform:

以上这篇TensorFlow实现打印每一层的输出就是小编分享给大家的全部内容了，希望能给大家一个参考，也希望大家多多支持脚本之家。
