Actual behavior

Does nothing

Expected behavior

Run the file I said no matter what file I am on.

Steps to reproduce:

1. IDK

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:

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

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?

how do I find the PTVSD version?

[int19h]

Ah, I see the problem. You're using "module", but then specifying the path to the file - it should be a fully qualified module name instead. Or if you really do want to start it as a file, then it must be "program" rather than "module".

Basically, this:

"program": "foo/bar.py"

is as if you did this from command line:

python foo/bar.py

and this:

"module": "foo.bar"

is as if you did:

python -m foo.bar

Note that in the latter case, you're also responsible for ensuring that the current directory and/or PYTHONPATH is such that foo.bar can be resolved.

but when I try to add a configuration VS code asks me for different options. Which one do I choose?

[brando90]

how do you have VS code fill in for your home path? i.e. if I had ~/foo/main.py, how can I have VS code fill for ~?

[int19h]

You should pick the one that is most appropriate to your use case. Based on the configuration you've show, it sounds like "Python File" will work better for you. You can edit launch.json afterwards so that it always starts a particular named file, instead of the currently selected one.

Here is the list of all variable substitutions that can be done in launch.json. I don't think there's anything specifically for ~, but you should be able to use {env:HOME} (on Linux and OS X) or {env:USERPROFILE} (on Windows) to similar effect.

{env:HOME}

I get an error:

FileNotFoundError: [Errno 2] No such file or directory: '{env:HOME}/automl-meta-learning/automl/experiments/experiments_model_optimization.py

code:

        {
            "name": "Python: Experiments Protype1",
            "type": "python",
            "request": "launch",
            "program": "{env:HOME}/automl-meta-learning/automl/experiments/experiments_model_optimization.py",
            "console": "integratedTerminal"
        }

thanks for the help btw.

works, dont forget the money sign! $

            "name": "Python: Experiments Protype1",
            "type": "python",
            "request": "launch",
            "program": "${env:HOME}/automl-meta-learning/automl/experiments/experiments_model_optimization.py",
            "console": "integratedTerminal"
        }
