1. 系统配置文件

ubuntu配置文件一般都在.bashrc或.profile中，mac在.bashprofile中

2. 安装低版本tensorflow

How to download previous version of tensorflow? (tf0.11没有gpu版本)

3. .sh文件运行

• source FILENAME.sh
• chmod u+x FILENAME.sh

  4. GPU监视

  watch -n 10 nvidia-smi

  5. Ubuntu安装pyenv

  $ curl -L https://github.com/pyenv/pyenv-installer/raw/master/bin/pyenv-installer | bash
  

  .bashrc中配置路径

  export PYENV_ROOT="$HOME/.pyenv"
  export PATH="$PYENV_ROOT/bin:$PATH"
  eval "$(pyenv init -)"
  

  6. Ubuntu查看系统日志

  tail /var/log/messages
  

  if not:

  vim /etc/rsyslog.d/50-default.conf
  

  将下面代码的注释取消，并wq保存退出

  #*.=info;*.=notice;*.=warn;\  
  #       auth,authpriv.none;\  
  #       cron,daemon.none;\  
  #       mail,news.none          -/var/log/messages  
  

  重启rsyslog系统

  sudo service rsyslog restart  
  

  7. If Linux interface is stucked…

  alt+ctrl+F1 come into command line mode, then alt+ctrl+F7 come into GUI mode.

8. Set up the permanent alias for a complicated command line

vim ~/.bashrc

add alias NewName='The Original Command Line' to .basrc,
then source ~/.bashrc

9. Check the on-going backend scripts

ps aux | grep py

10. Run the code without interrupting

nohup python -u script.py

11. Redirect nohup file to another file

nohup some_command &> NEW_name.out&
