• 首先要安装virtualenv

$ sudo apt-get install python-pip python-dev python-virtualenv 

• 创建虚拟环境（如果使用默认的python版本则无需-p命令，如果要用指定的python版本，则使用-p命令来指定；我们假定创建的虚拟环境为tensorflow，即targetDirectory为tensorflow）

$ virtualenv -p /usr/bin/期望使用的python版本 targetDirectory 

• 激活虚拟环境

$ source ~/tensorflow/bin/activate

• 激活之后的虚拟环境变为

(tensorflow)$

• 在激活的虚拟环境中安装TensorFlow

 (tensorflow)$ pip install --upgrade tensorflow      # for Python 2.7
 (tensorflow)$ pip3 install --upgrade tensorflow     # for Python 3.n
 (tensorflow)$ pip install --upgrade tensorflow-gpu  # for Python 2.7 and GPU
 (tensorflow)$ pip3 install --upgrade tensorflow-gpu # for Python 3.n and GPU

• 如果上面的命令执行之后安装失败，则说明pip版本太低，无法通过https来下载，可以升级pip版本

 (tensorflow)$ pip install --upgrade TF_PYTHON_URL   # Python 2.7
 (tensorflow)$ pip3 install --upgrade TF_PYTHON_URL  # Python 3.N 

• 如果升级失败，依然无法安装TF的话，则直接执行下面的命令，通常都可以安装成功

  • Python2.7(CPU/GPU)

    (tensorflow)$ pip install --ignore-installed --upgrade \

    (tensorflow)$ pip install --ignore-installed --upgrade \

  • Python3.4(CPU/GPU)
