1. 工具包安裝

            
              pip install virtualenv | sudo apt-get install python-virtualenv

            
          

2. 創建虛擬環境

            
              # virtualenv /system_python_bin_path  /your_virenv_local_path
virtualenv -p /usr/bin/python2.7 /usr_local_path

# 創建鏈接
sudo ln -sf /usr_local_path/bin/activate tf_activate
sudo ldconfig -v

# 啟動 虛擬環境: 
source tf_activate

# "一頓操作，安裝環境; 只在當前虛擬環境安裝，不會影響系統環境下的 Python"
pip install tensorflow-gpu
pip install opencv-contrib-python
.....

#終止: 
deactivate
