import tensorflow：FutureWarning:

 import tensorflow 出现如下错误警告：

本人是在windows 10下 anaconda  对应python3.6版本

>>> import tensorflow

d:\ProgramData\Anaconda3\lib\site-packages\h5py\__init__.py:36: 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

查找网上资料，通过更新 h5py版本解决。h5py 原版本  2.7.1，采用如下命令：

pip install "h5py==2.8.0rc1",  

之后，再重新导入 警告已经消失。
