解決h5py的FutureWarning問題

 

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 和 numpy 版本沖突，h5py 官方已修復合並到 master 分支，但是還沒發新版，在發版之前可以用降級 numpy 的方法跳過這個問題。

降級命令如下：

$ pip install numpy==1.13.0
