How to correctly set specific module to debug in VS code?

Charlie Parker :

I was following the instruction by VS code's website but it seemed that nothing that I tried worked.

I created a new configuration as required but whenever I put the path it refuses to work in VS code although the path VS code complains about in the integrated terminal window works fine when I call it manually.

The error the debugger throws is the following:

/Users/brandomiranda/miniconda3/envs/automl-meta-learning/bin/python: Error while finding module specification for '/Users/brandomiranda/automl-meta-learning/automl/experiments/experiments_model_optimization.py' (ModuleNotFoundError: No module named '/Users/brandomiranda/automl-meta-learning/automl/experiments/experiments_model_optimization')

then I tried running the file it complains manually and it runs it just fine...

(automl-meta-learning) brandomiranda~/automl-meta-learning/automl/experiments ❯ python /Users/brandomiranda/automl-meta-learning/automl/experiments/experiments_model_optimization.py
--> main in differentiable SGD
-------> Inside Experiment Code <--------

---> hostname:

device = cpu
Files already downloaded and verified
Files already downloaded and verified
Files already downloaded and verified

even when I hover over the path name and click it with command + click then it takes me to the path from within VS code. Which seems bizzare. So somehow only when I run it in debugger mode does it not work. Why?

Gabriel C :

You are using module instead of program in launch.json. When using module you must pass only the module\sub-module name, not the entire path. Visual Studio will then load the specified module and execute it's __main__.py file.

This would be the correct input, assuming automl is a module and experiments is a submodule:

"module": "automl.experiments"

If you want to point to your script directly you can use the path you were using previously, just changing module to program:

"program": "${workspaceFolder}/automl/experiments/experiments_model_optimization.py"
