1.运行到如下代码时发生错误：
sw = tf.summary.FileWriter(TENSORBOARD_DIR)
2.报告的错误为：
/home/mengzhuo/PycharmProjects/dai20180321/venv1/bin/python /home/mengzhuo/PycharmProjects/dai20180321/keras_wacgan.py /home/mengzhuo/PycharmProjects/dai20180321/venv1/lib/python3.5/site-packages/h5py/__init__.py:36: FutureWarning: Conversion of the second argument of issubdtype from 'float' to 'np.floating' is deprecated.

3.解决办法：
- 把TENSORBOARD_DIR的值从相对路径改为绝对路径，比如我把：
TENSORBOARD_DIR = '/tensorboard/wgans/'
改为了：
TENSORBOARD_DIR = '/home/mengzhuo/PycharmProjects/dai20180321/tensorboard/wgans'
参考：
Tensorflow下使用 tf.summary.FileWriter()，提示 PermissionDeniedError
