深度学习框架keras:如何设置后端Tensorflow/theano

修改keras配置文件，可以更改keras后端依赖的框架：

sudo gedit ~/.keras/keras.json

{
    "epsilon": 1e-07, 
    "floatx": "float32", 
    "image_data_format":"channels_last" ,
    "backend": "tensorflow",
    "image_dim_ordering":"th"
}

把tensorflow改为theano，
同时把channels_last改为channels_first,
即可切换后端框架，如下：

{
    "image_data_format": "channels_first",
    "epsilon": 1e-07,
    "backend": "theano",
    "floatx": "float32"
    "image_dim_ordering":"th"
}
