ubuntu16.04上安装tensorflow( cpu)

ubuntu-16.04-desktop-amd64，
里面自带的python是2.7.11
1）首先安装pip

 sudo apt-get install python-pip python-dev

2）利用pip安装tensorflow

sudo pip install --upgrade https://storage.googleapis.com/tensorflow/linux/cpu/tensorflow-0.8.0-cp27-none-linux_x86_64.whl

3) 检验tensorflow是否安装成功
通过下面一段代码来测试tensorflow是否安装成功：

$ python
>>> import tensorflow as tf
>>> hello = tf.constant('Hello, TensorFlow!')
>>> sess = tf.Session()
>>> print(sess.run(hello))
Hello, TensorFlow!
>>> a = tf.constant(10)
>>> b = tf.constant(32)
>>> print(sess.run(a + b))
