第一：

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

解决办法：这是因为h5py包出错，将h5py升级到最新版就可以啦。

第二：

Your CPU supports instructions that this TensorFlow binary was not compiled to use: AVX2 FMA
 

解决方法：在代码中加入下面两句

                 import os

                 os.environ['TF_CPP_MIN_LOG_LEVEL'] = '2'
输入1：显示所有信息

       2：只显示warning和error

       3：只显示error
