vscode debugger warning on frozen modules

Question

Trying to use the multiprocessing module to run some code. I need to use the python debugger to pass '-Xfrozen_modules=off' but using args or pythonArgs in launch.json doesn't seem to work.

0.01s - Debugger warning: It seems that frozen modules are being used, which may
0.00s - make the debugger miss breakpoints. Please pass -Xfrozen_modules=off   
0.00s - to python to disable frozen modules.
0.00s - Note: Debugging will proceed. Set PYDEVD_DISABLE_FILE_VALIDATION=1 to disable this validation.

I passed '-Xfrozen_modules=off' using args and pythonArgs in launch.json but that didn't work.

Python 3.11.2

Answer 1

I ended up added the environment variable "PYDEVD_DISABLE_FILE_VALIDATION" to my launch.json file. For example:

{
    // Use IntelliSense to learn about possible attributes.
    // Hover to view descriptions of existing attributes.

    "version": "0.2.0",
    "configurations": [
        {
            "name": "Python: Current File",
            "type": "python",
            "request": "launch",
            "program": "${file}",
            "console": "integratedTerminal",
            "justMyCode": true,
            "env": {
                "PYDEVD_DISABLE_FILE_VALIDATION": "1"
              }
        }
    ]    
}
