运行tensorflow出现FutureWarning，这个意义不大
在win10 64位运行tensorflow出现问题：
1 | FutureWarning: Conversion of the second argument of issubdtype from float to np.floating is deprecated. In future, it will be treated as np.float64 == np.dtype(float).type.from ._conv import register_converters as _register_converters。 |
经过查阅资料,解决方法：
1 | pip install h5py==2.8.0rc1 |
