Current working directory for jupyter notebook sets to temp folder in vscode

问题

I'm trying to set current working directory (CWD) to edited file location for Jupyter Notebook in VS Code. I use ${fileDirname} in python.dataScience.notebookFileRoot setting. However it uses temporary folder as ${fileDirname} instead of original file folder.

Same issue was discussed couple times already (e.g. https://stackoverflow.com/a/54794976/12488601) with tried solution pointed out.

Here is example of cwd:

os.getcwd()
.. 'C:\\Users\\MjH\\AppData\\Local\\Temp\\1f6cc207-562f-4ae1-8754-e2013ae2c12d'

While expected result is C:\Workspace\Project.

So use of ${fileDirname} does not work in my case. I use following ad-hoc solution, which, obviously, won't update if file is moved.

import sys
import os
sys.path.insert(0, r'C:\workspace\project')
os.chdir(sys.path[0])

Now I'm trying to understand three things:

is my case a unique one?
if it's general issue, is there a feature request/issue submitted for VS Code to address it?
is there a better ad-hoc solution?

VS Code version: Code 1.40.2 (f359dd6, 2019-11-25T14:54:45.096Z)
OS version: Windows_NT x64 10.0.17763

I'm also affected by this issue. Here is how I solved it.

Using the configuration parameter of ${fileDirName} in Python > DataScience: Notebook File Root, has this effect as I could check in my environment.

If I open an Python Interactive Window using the commands Ctrl+Shift+P > Python:Show Python Interactive Window, and then run:

import os
os.getcwd()

The output is a random temporal folder. So I couldn't do imports cause my local relative modules where not found.

However, If instead of opening directly a fresh Python Interactive Window I run a cell of code of any of my python files

#%%
print("Epstein didn't kill himself)

and then find the current working path, it changes to the fileDirName as expected. Then any interaction with the interactive window will perform correctly (and my next imports will perfom correctly).

To avoid this behaviour and because I would like to perform operations within my workspaceFolder I changed Python > DataScience: Notebook File Root to ${workspaceFolder}. In this case opening a new fresh Python Interactive Window, will set the current path automatically to the workspaceFolder, with and without the need to execute any python cell.

I think that, when using ${fileDirName}, it would be good to set the current working open file folder as the working path of the Python Interactive Window (Jupyter) instead of the temporal random folder (In the case of opening without executing a specific cell), but doesn't look like it behaves like that.

Hope it were usefull!

To answer your third question, try this:

import os

os.system("echo %cd% > dir")
file = open("dir", "r")
filePath = file.read()
file.close()

print(filePath.split("\n")[0])
