VS Code and python debugger returning error but can run in the terminal

Question

I am trying to run the code I have made for some plots and I can fully run it on terminal and spyder (I want to switch from spyder to VS code complete for data analysis) but I keep receiving an error saying my CSV file is not found, while if I run this directly on my terminal or spyder I don't get such error

So if I try to run my code using the run cell from VS Code I get this error:

import pandas as pd...
import pandas as pd...

    701 
--> 702         return _read(filepath_or_buffer, kwds)

Sorry for the not wrapped code here, apparently markdown doesn't support this. The code I am trying to run is:

#%% #for jupyter notebook 

import pandas as pd
from matplotlib import pyplot as plt
import numpy as np


LNA_w2Path_PAC_AND_PSP = pd.read_csv('../../Results/CSV/LNA_w2Path_PAC_AND_PSP.csv')
LNA_w2Path_PAC_AND_PSP.columns = LNA_w2Path_PAC_AND_PSP.columns.str.strip().str.lower().str.replace(' ', '_').str.replace('(', '').str.replace(')', '').str.replace('/', '').str.replace('=','_').str.replace(';','')
plt.figure()
plt.plot(LNA_w2Path_PAC_AND_PSP.net18net049_h_0__pac_db20vv_harmonic_0_x/1E9, LNA_w2Path_PAC_AND_PSP.net18net049_h_0__pac_db20vv_harmonic_0_y, linewidth=2.0)
plt.ylabel("$\mathrm{Harmonic \ response \ (dB)}$")
plt.xlabel("$\mathrm{Frequency \ (GHz)}$")
plt.title("Harmonic response of LNA+2-Path Filter")
plt.grid(True, which="both")
plt.show()

If I simply run a python3 myfile.py it works fine.

EDIT

My .json file looks like this:

{
    "git.autofetch": true,
    "python.pythonPath": "/home/theis/anaconda3",
    "window.zoomLevel": 2,
    "editor.find.addExtraSpaceOnTop": false,
    "editor.suggestSelection": "first",
    "vsintellicode.modify.editor.suggestSelection": "automaticallyOverrodeDefaultValue",
    "python.jediEnabled": false,
    "workbench.colorTheme": "Dracula Soft",
    "python.linting.pylintEnabled": false,
    "python.linting.enabled": false,
    "languageTool.language": "en-US",
    "julia.enableTelemetry": true,
    "python.terminal.executeInFileDir": true
}

EDIT2:

So I added "cwd": "${fileDirname}" to my launch.json and tried to run this code in both debugger and using the jupyter notebook extension:

#%%

import os
print("Hello World!")
print(os.getcwd())

The debugger returns:

Hello World!
/home/theis/code/N_path_intership/PlottingCode/python

and the jupyter notebook extension returns:

Hello World!
/home/theis/code/N_path_intership/PlottingCode

Probably that the current working directory of your debugger is different from the one of your default running terminal — Thibault D.

In the debug menu, click on the little setting icon to open launch.json. Your file should look like that:

{
    "version": "0.2.0",
    "configurations": [
    {
            "name": "Python: Current File (Integrated Terminal)",
            "type": "python",
            "request": "launch",
            "program": "${file}",
            "console": "integratedTerminal",
    }, 

    //... other settings, but I modified the "Current File" setting above ...
}

You can add a cwd key (which means current working directory) and set it to what you want:

{
    "version": "0.2.0",
    "configurations": [
    {
            "name": "Python: Current File (Integrated Terminal)",
            "type": "python",
            "request": "launch",
            "program": "${file}",
            "console": "integratedTerminal",
            "cwd": "${fileDirname}/<WhateverYouWant>"
    }, 

    //... other settings, but I modified the "Current File" setting above ...
}

It should solve your problem with the right path.

Should I truly add something after the fileDirname i.e: "${fileDirname}/myfolder" because as far I understood the fileDirname already does the job of getting the path by itself. I have added "cwd": "${fileDirname}" without any success.

Maybe this answer can help you: https://stackoverflow.com/a/49275867/9628974

It's about changing the VSCode settings to execute python in the file's firectory.

This was set already (I have added the .json file in the EDIT)
