A1. Debugging Python in VS Code

i have conda environment "llama-0.4" configured in my terminal, and i can run "output_parsers_demo.py" there without any problem, since all necessary modules like "langchain" are installed there. i would like to debug this script in vs code. what approach would you recommend for that?

Use VS Code’s debugger with the same Python interpreter as your working conda env.

Recommended steps:

In VS Code, run Python: Select Interpreter
Choose the interpreter from your conda env llama-0.4
Open output_parsers_demo.py
Set breakpoints
Press F5 to debug

Best practice: add a launch.json like this:

{
  "version": "0.2.0",
  "configurations": [
    {
      "name": "Debug output_parsers_demo.py",
      "type": "debugpy",
      "request": "launch",
      "program": "${workspaceFolder}/output_parsers_demo.py",
      "console": "integratedTerminal",
      "cwd": "${workspaceFolder}",
      "justMyCode": false,
      "envFile": "${workspaceFolder}/.env"
    }
  ]
}

Why this works:

VS Code debug sessions may not inherit your terminal’s activated conda env.
What matters is the interpreter VS Code uses.
envFile helps ensure your API keys and other variables are available.

Quick check: in VS Code’s integrated terminal, run:

which python
python -V
python -c "import langchain; print('ok')"
