提示：/root/anaconda3/lib/python3.6/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
原因：h5py numpy 这俩有冲突，安装低版本的numpy可解决问题
解决：conda install numpy==1.13.3 （运行此命令替换现有版本的numpy）
