（2）安装环境：Ubuntu18.04， tensorflow1.14， nvidia显卡驱动：455
（3）解决方案：
Problem scenario:
/usr/bin/env: ‘python’: No such file or directory
Possible Solution #1
If Python 3 is not installed, install it: apt-get install python3
Possible Solution #2
If Python 3 has been installed, run these commands: `whereis python3`
Then we create a symlink to it: `sudo ln -s /usr/bin/python3 /usr/bin/python`
