File Not found when running python source file in console (default run button)

[nc7400]

Hi all, I cannot run python source files "in console," which is the default run button action. I get the following error:

Python 3.11.9 (Global) started.

I just tried on my local windows machine and I can't reproduce the error, with the same Positron version and a User build.

I do see that your %run command looks like the escaping of the path is wrong.

[nc7400]

This issue occurs when I hit "Run Python File in Console", for some reason it does say the file is not found that is in fact in the folder.

It definitely looks like something is going wrong with path escaping there! Notice where it says this (looks OK):

%run "c:\\Users\\nathaniel.culberson\\Repositories\\KYWSS-main\\2_create_WVAL_data.py"

But then this (not OK):

OSError: File `'\'"c:\\\\Users\\\\nathaniel.culberson\\\\Repositories\\\\KYWSS-main\\\\2_create_WVAL_data.py"\''` not found.

The code that finds the file is coming from ipython here:

https://github.com/ipython/ipython/blob/aa25535d3765641e31f1d218537540e41b6f1a74/IPython/utils/path.py#L83-L90

Could you try running some of that interactively in the console, to see what is happening (since we can't reproduce the problem)? Something like this:

import os
name = os.path.expanduser("c:\\Users\\nathaniel.culberson\\Repositories\\KYWSS-main\\2_create_WVAL_data.py")
os.path.isfile(name)

[nc7400]

Sure, I tried that code and it came back True.

Thanks for your patience on this! We are still not able to reproduce this problem on our side, but I've got a couple of followup questions:

• Does the latest available build of Positron exhibit the same problem?
• Did you install ipykernel for yourself, or did you use the bundled ipykernel that Positron includes? You can read more on this here: https://positron.posit.co/start.html#python-prerequisites
• What happens if you use the magic directly, not via the button? i.e. paste %run "c:\\Users\\nathaniel.culberson\\Repositories\\KYWSS-main\\2_create_WVAL_data.py" in the console
• If that still errors (which I am guessing it must) then can you run that same code in the non-Positron ipython repl?
