virtualenv 安裝

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

安裝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
