### virtualenv 安装 ###

1.Install pip and Virtualenv by issuing the following commands :

$ sudo easy_install pip
     $ pip install --upgrade virtualenv

2.Create a Virtualenv environment by issuing a command of one of the following formats:

$ virtualenv --system-site-packages [targetDirectory] # for Python 2.7
     $ virtualenv --system-site-packages -p python3 [targetDirectory] # for Python 3.n

3.Activate the Virtualenv environment by issuing one of the following commands:

$ cd [targetDirectory]
    $ source ./bin/activate      # If using bash, sh, ksh, or zsh
    $ source ./bin/activate.csh  # If using csh or tcsh

The preceding source command should change your prompt to the following:

(targetDirectory)$

4.Ensure pip ≥8.1 is installed:

(targetDirectory)$ easy_install -U pip

5.退出virtualenv

(targetDirectory)$ deactivate

### 安装TensorFlow ###

1.Issue one of the following commands to install TensorFlow and all the packages that TensorFlow requires into the active Virtualenv environment:

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