'''

'''
命令行运行 python demo.py --host 127.0.0.1 --port 22 --user root
可以看到输出结果
在vscode点击debug的图标-->create a launch.json file--->python File
初始的json文件如下:
{
// Use IntelliSense to learn about possible attributes.
// Hover to view descriptions of existing attributes.
// For more information, visit: https://go.microsoft.com/fwlink/?linkid=830387
"version": "0.2.0",
"configurations": [
{
"name": "Python: Current File",
"type": "python",
"request": "launch",
"program": "${file}",
"console": "integratedTerminal",
"justMyCode": true
}
]
}
Ctrl+shif+p切换python环境并更改./vscode/launch.json如下
{
// Use IntelliSense to learn about possible attributes.
// Hover to view descriptions of existing attributes.
// For more information, visit: https://go.microsoft.com/fwlink/?linkid=830387
"version": "0.2.0",
"configurations": [
{
"name": "Python: Current File",
"type": "python",
"request": "launch",
"program": "${file}",
"console": "integratedTerminal",
"justMyCode": true,
"env": {
"CUDA_VISIBLE_DEVICES":"4" // 设置cuda
},
// 添加参数
"args":[
"--host", "127.0.0.1",
"--port", "22",
"--user","root"
]
}
]
}
之后打断点按F5或者Run-->Start Debugging 就可以了
