Jupyter doesn't update env values on restart when .env file gets updated

[vladpy8]

Applies To

• Notebooks (.ipynb files)
• Interactive Window and/or Cell Scripts (.py files with #%% markers)

What happened?

Hello

It seems that VSCode and Juputer extension don't update environment variable values, when value is changed in .env file.

.env file is located in VSCode/Juyter/project root directory

Action, which, I believe, will reproduce issue:

1. Set some variable value in .env:

MY_CUSTOM_VAR=value_1

2. (Re)Start .ipynb and check value has been set:

os.getenv('MY_CUSTOM_VAR')

'value_1'

3. Change value of the very same variable in .env:

MY_CUSTOM_VAR=value_2

4. Reload and restart VSCode and kernels as many times as you believe necessary, but at least once
5. Observe that variable's value doesn't change:

os.getenv('MY_CUSTOM_VAR')

'value_1'

Is that intended behaviour?

I use conda environment packaged with python, ipykernel and jupyter:

name: test
channels:
  - conda-forge
  - defaults
  - microsoft
dependencies:
  - tqdm
  - jupyter
  - lxml
  - python=3.9
  - matplotlib
  - pandas[version='>=1.4']
  - ipykernel
  - openpyxl
  - gspread
  - aiohttp[version='>=3.8']
  - pylint
  - dataframe_image

(some packages have been removed for security reasons, but should work)
