解决import tensorflow时，h5py的FutureWarning问题

当引入import tensorflow as tf 时，会出现这个警告：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 

 

解决的办法：先把numpy更新，再把h5py更新。

更新命令：pip install --upgrade numpy  

                  pip install --upgrade h5py
