VSCode: Debug Python

Here is my template repository of building a Python project (with Pytorch and cutomized CUDA kernels): VSC-Pytorch-Project-Template !

First, add the following code to “./.vscode/launch.json” (create the file if it does not exist):

{
    "version": "0.2.0",
    "configurations": [
        // Other configurations...,
        {
            "name": "DebugPy: Current File",
            "type": "debugpy",
            "request": "launch",
            "console": "integratedTerminal",
            // Whether to jump to external code when debugging
            "justMyCode": true,
            // Path to the Python file to debug; If set to "${file}", it will 
            // use the currently opened file
            "program": "${file}",
            // Arguments to pass to the program
            "args": [
                "<arg1>",
                "<arg2>",
                // ...
            ],
            // Environment variables
            "env": {
                "<YOUR_ENV_VAR>": "<VALUE>"
            },
        },
        // Other configurations...,
    ]
}

Next, click on the “Run and Debug” icon on the left sidebar, choose the configuration with the name you specified in “launch.json”, then click on the green play button to start debugging.
