windows 10 下 pip,conda 換國內源，安裝Tensorflow,Keras

修改pip源 參考 Python pip 國內映象大全及使用辦法

官方文件 Config file

windows 全部使用者需要在%APPDATA%\pip\pip.ini,當前使用者在%HOME%\pip\pip.ini

安裝Tensorflow

參考 Installing TensorFlow on Windows 

# 切換到 python3.5 參考 詳見另外一篇博文 https://anjia.ml/2017/07/02/anaconda-install-and-configurating-jupyter/#切換python版本

#開啟Anaconda Prompt
(python35) C:\Users\xx> activate python35

#因為電腦無獨顯，所以安裝`CPU-only`版本
(python35) C:\Users\xx> pip install --ignore-installed --upgrade https://storage.googleapis.com/tensorflow/windows/cpu/tensorflow-1.2.1-cp35-cp35m-win_amd64.whl

>>> hello = tf.constant('Hello, TensorFlow')
>>> sess = tf.Session()

如果要去掉4-12的警告資訊，需要自己編譯。詳見 "The TensorFlow library wasn't compiled to use SSE instructions, but these are available on your machine and could speed up CPU computations" in "Hello, TensorFlow!" program #7778

安裝Keras

參考 官方文件 Installation 中文文件 Keras安裝和配置指南(Windows)

(python35) C:\Users\xx>pip install keras -U --pre複製程式碼

但是我安裝一直報錯，

網上有建議通過 pip install git+git://github.com/Theano/Theano.git 從github直接下最新程式碼安裝的，但是也是安裝失敗

我成功的方式

(python35) C:\Users\xx>conda install mingw libpython theano -y
(python35) C:\Users\xx>pip install keras複製程式碼

天朝網路不穩定，挺慢的，可以參考 另外一篇博文切換清華源 anjia.ml/2017/07/02/…

(python35) C:\Users\xx>python

Type "help", "copyright", "credits" or "license" for more information.
>>> import keras

安裝成功，預設後端是TensorFlow
