数据处理：
去掉csv文件第一行：sed 1d train_data_deled_col.csv > del_line.csv
去掉csv文件第一列：del_col.py

可视化：

• 启动服务器：python -m visdom.server
  • 命令行选项：-port：端口号
• 代码：vis = visdom.Visdom(port=2333,env='example') //port缺省值为8097，env缺省值为'main'

查看显卡情况：nvidia-smi，nvidia-smi -l
释放显存：

$ ps aux|grep python // 查看python程序的pid
$ kill -9 PID // 杀死进程

解释（https://webcache.googleusercontent.com/search?q=cache:u9tKrJzaMZkJ:https://discuss.pytorch.org/t/gpu-memory-not-returned/1311+&cd=1&hl=zh-CN&ct=clnk）：

ps x |grep python|awk '{print $1}'|xargs kill
ps x: show all process of current user
grep python: to get process that has python in command line
awk '{print $1}': to get the related process pid
xargs kill: to kill the process

note: make sure you don’t kill other processes! do ps x |grep python first.

since I usually use the jupyter notebook, so I use grep ipykernel

ps x |grep ipykernel|awk '{print $1}'|xargs kill
there should be an elegant way to kill the related process using only ps+awk
