tensorflow使用記錄（一）安裝

ubuntu16.04  64-bit 
python3.5 
virtualenv
docker

ref: https://www.tensorflow.org/versions/r0.11/get_started/os_setup.html#virtualenv-installation
官網上有詳細的安裝流程，考慮到對現有python環境的影響，我準備用docker或virtualenv安裝

virtualenv安裝tensorflow

1. install pip and virtualenv
2. create a virtualenv environment
3. activate the virtualenv environment and install tensorflow in it

4. after the install you will activate the virtualenv environment each time you want to use tensorflow

    $ sudo apt-get install python3-pip python3-dev python3-virtualenv
    $ virtualenv --system-site-packages ~/tensorflow
    $ source ~/tensorflow/bin/activate
   
    (tensorflow)$                      #your prompt should change
    選擇適合自己的安裝包
    # Ubuntu/Linux 64-bit, CPU only, Python 3.5
   (tensorflow)$ export TF_BINARY_URL=https://storage.googleapis.com/tensorflow/linux/cpu/tensorflow-0.11.0rc0-cp35-cp35m-linux_x86_64.whl
   #install tensorflow
   (tensorflow)$ pip3 install --upgrade $TF_BINARY_URL
   
   #test your installation
   (tensorflow)$ python3
   >>> import tensorflow as tf
   >>> hello = tf.constant('Hello, TensorFlow!')
   >>> sess = tf.Session()
   >>> sess.run(hello)
   Hello, TensorFlow!
   >>> a = tf.constant(10)
   >>> b = tf.constant(32)
   >>> sess.run(a+b)
   42
   >>>exit()
   
   #結束使用tensorflow virtualenv
   (tensorflow)$ deactivate
   $                                  #your prompt should change
   

Docker安裝Tensorflow

docker安裝過程中一種pulling不下來鏡像，待續…
用了vpn後pulling下來了…
docker的安裝和使用見docker使用記錄

$ docker run -it -p 8888:8888 gcr.io/tensorflow/tensorflow

Tensorflow使用

Pycharm

在pycharm中可以在setting——>project interpretor中選擇之前建立好的tensorflow virtualenv虛擬環境中的python3,這樣就可以在pycharm中用啦
