StdErr from ShellExec, stty: stdin isn't a terminal

[pokey]

When I try to run a cell in a Jupyter notebook, I get the following error:

StdErr from ShellExec, stty: stdin isn't a terminal stty: stdin isn't a terminal stty: stdin isn't a terminal stty: stdin isn't a terminal for . /Users/pokey/.venv/flashcards-test/bin/activate && echo '718d24f2-8b10-48f3-8ad3-723876a19613' && python /Users/pokey/.vscode/extensions/ms-python.python-2020.11.371526539/pythonFiles/pyvsc-run-isolated.py /Users/pokey/.vscode/extensions/ms-python.python-2020.11.371526539/pythonFiles/printEnvVariables.py

Thanks for replying this issue

Please confirm this option environment is 3.8 and it's a venv Users/pokey/.venv/flashcards-test/bin/activate

[DonJayamanne]

Please could you open the python output panel and copy the contents from that too, I'm interested in the first 10 lines of the output (to see what experiments this instance of vscode belongs to)

[DonJayamanne]

We have been looking into this issue for a few days now and found that some users managed to get this working switching to the latest version of VSCode insiders.

Please could you let us know whether it works for you when you use VSCode insiders. Total help narrow down the problem.
Thanks again

Thanks for the quick response! To answer your questions:

Yes it's a venv, but it is Python 3.7.3

Nope same issue with insiders' build 😕

Fwiw I have pyenv-virtualenv installed on my system, but I'm not using that for this virtualenv, and it appears that it shouldn't have an impact; when I open a terminal in VSCode here's what I get:

➜ source /Users/pokey/.venv/flashcards-test/bin/activate
➜ python --version
Python 3.7.3
➜ which python
/Users/pokey/.venv/flashcards-test/bin/python

Note that the first line wasn't typed by me, but automatically by VSCode

I'm having a similar issue when I try to run a jupyter notebook. My error is:
StdErr from ShellExec, This program is blocked by group policy. For more information, contact your system administrator. This program is blocked by group policy. For more information, contact your system administrator. for C:/Users/142522/AppLockerExceptions/Anaconda3/Scripts/activate && conda activate base && echo 'e8b39361-0157-4923-80e1-22d70d46dee6' && python c:\Users\142522\.vscode\extensions\ms-python.python-2020.11.371526539\pythonFiles\pyvsc-run-isolated.py c:/Users/142522/.vscode/extensions/ms-python.python-2020.11.371526539/pythonFiles/printEnvVariables.py

I get this error when I try to run bash files through cmd. So I need to do all of my python stuff through the powershell, where I can set the argument to bypass the execution policy. I have set that as the default terminal in my settings.json:
"terminal.integrated.shell.windows": "C:\\WINDOWS\\System32\\WindowsPowerShell\\v1.0\\powershell.exe", "terminal.integrated.shellArgs.windows": [ "-NoExit", "-ExecutionPolicy", "ByPass", "-Command", "& 'C:\\Users\\142522\\AppLockerExceptions\\Anaconda3\\shell\\condabin\\conda-hook.ps1' ; conda activate 'C:\\Users\\142522\\AppLockerExceptions\\Anaconda3'" ], "python.terminal.activateEnvironment": false,
and everything works fine when I run a terminal in vscode, however, when I try to run a jupyter notebook, it doesn't seem to be using the powershell shell to initialise the kernel.
