Python问题：AttributeError: ‘str‘ object has no attribute ‘decode‘

具体报错情况：

AttributeError                            Traceback (most recent call last)

AttributeError: 'str' object has no attribute 'decode'

 keras与h5py版本不兼容。
查看h5py的版本，未安装，自动安装后

pip install h5py==2.10.0

在2.10版本中，字符串的存储是经过编码的，而在3.0.0的版本中，则不会检查是否经过编码。所以才会出现最初的AttributeError: ‘str’ object has no attribute ‘decode’。

发现h5dict与h5py不兼容

卸载h5dict

 pip uninstall h5dict

安装

pip install h5dict==0.2.0 

运行一下 继续报错了

AttributeError: 'bytes' object has no attribute 'encode'

 但报错文档未出现encode（“utf-8”）

重启Jupyter notebook，重新打开即可
