深度学习框架keras安装（后端基于Tensorflowtheano）

1、安装python3、tensorflow、numpy、scipy

安装python3及开发工具

sudo apt-get install python3 sudo apt-get install python-setuptools

安装pip

sudo apt-get install python3-pip

安装tensorflow/numpy/scipy

pip3 install numpy pip3 install scipy pip3 install tensorflow

2、安装keras

pip3 install keras

3、安装成功之后的效果

ubuntu:~$ python3 Python 3.5.3 (default, Jan 19 2017, 14:11:04) [GCC 6.3.0 20170118] on linux Type "help", "copyright", "credits" or "license" for more information. >>> import keras Using TensorFlow backend. >>> exit()

修改keras配置文件，可以更改keras后端依赖的框架： vim ~/.keras/keras.json

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

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" }
