Warning对应Conversion of the second argument of issubdtype from `float` to `np.floating` is deprecated
现象
import tensorflow 的时候提示如下信息
/anaconda2/lib/python2.7/site-packages/h5py/init.py:36: FutureWarning: Conversion of the second argument of issubdtype fromfloattonp.floatingis deprecated. In future, it will be treated asnp.float64 == np.dtype(float).type.
from ._conv import register_converters as _register_converters
原因
原因已经提示在Warning信息中了，升级h5py即可，其实这个问题，在单独import h5py的时候也会直接碰到
