About adding batch normalization #1
Description
博主，你好！
非常感谢你的开源代码！对于我理解DDPG有非常大的帮助！
我使用你的开源代码在新的environment中进行DDPG学习的时候，出现了输出的动作总是动作边界值的情况。经过查找资料，我认为batch normalization可以解决这个问题。
于是，我在不同的层之间，使用tf.contrib.layers.batch_norm函数进行batch normalization。但是改动之后，我收到了很长的一堆报错。

我的系统是ubuntu16.04，我使用的是tensorflow 1.14.0。
卡在这个问题上数天，依然未能解决这个问题。希望博主在有时间的时候可以帮忙解答。
谢谢博主！
