Please pass -Xfrozen_modules=off when debuging

[Guilherme (guilhermesilva07113)]

Hi there!

When I try to run Python Debugger: Debug Python File I get:

0.00s - 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.

My python file has the following modules:

import os
import pickle
import sys
import warnings

sys.path.insert(1, "../config/")

from datetime import datetime, timedelta

import pandas as pd

import config
from core_forecast.model_forecast import BaseExperimentalConstrutor, ModeloForecast, Oraculo, ArrumaPrevisaoNegativa
from core_forecast.utils.checks import check_if_variaveis_usuario_are_in_the_df
from core_forecast.utils.save_load import CriaParser, clear_directories, save_to_csv, save_to_json
from model_hyper_parameters import model_mapping
from utils.extra import new_data_from_window
from utils.metrics_porto import protocolo_erro_porto, relatorio_metricas_porto

My launch.json (even tough I am not using it):

{
    "version": "0.2.0",
    "configurations": [
        {
            "name": "Python Debugger: Current File",
            "type": "debugpy",
            "request": "launch",
            "program": "${file}",
            "console": "integratedTerminal", // internalConsole -> to prevent from printing
            "cwd": "${workspaceFolder}/src",
            "justMyCode": false,
            "python": "~/.conda/envs/time_series/bin/python",
            "pythonArgs": ["-Xfrozen_modules=off"],
            "args": [
                "-d","../data/05_model_input/comportamento_ALG_PRM/dados_input_model.csv",
                "-o","../data/07_model_output",
                ]
        }
    ]
}

So, how/where do I pass pass -Xfrozen_modules=off?

Thanks in advance!

Your launch.json should be the way to do it (pythonArgs). Python Debugger: Debug Python File doesn't use your launch.json though. You do that from the debugger pane in VS code.

Hi! Thank you for your reply.

Now I understood that Python Debugger: Debug Python File doesn't use your launch.json.

But

• Can I pass "pythonArgs": ["-Xfrozen_modules=off"] somewhere else?
• Or the only way to inform, it is through launch.json and Python Debugger: Debug Python File using launch.json?

tks

Guilherme (@guilhermesilva07113) You should be able to set "purpose" on the config in launch.json. Set it to "purpose": ["debug-in-terminal"] to use it as a part of Python Debugger: Debug Python File

Included:

{
    "version": "0.2.0",
    "configurations": [
        {
            "name": "Python Debugger: Current File",
            "type": "debugpy",
            "request": "launch",
            "program": "${file}",
            "console": "integratedTerminal",
            "cwd": "${workspaceFolder}/src",
            "justMyCode": false,
            "python": "~/.conda/envs/time_series/bin/python",
            "pythonArgs": ["-Xfrozen_modules=off"],
            "purpose":["debug-in-terminal"],
            "args": [
                "-d","../data/05_model_input/comportamento_ALG_PRM/dados_input_model.csv",
                "-o","../data/07_model_output",
                ]
        }
    ]
}

but I still got the same messages.

That feels like a bug, can you file a issue on https://github.com/microsoft/vscode-python-debugger
