I was unable to run that command:

/gge/venv/bin/python ~/.vscode/extensions/ms-python.python-2022.10.0/pythonFiles/testing_tools/run_adapter.py discover pytest -- --rootdir . -s --cache-clear
/gge/venv/bin/python: can't open file '/home/thiago/.vscode/extensions/ms-python.python-2022.10.0/pythonFiles/testing_tools/run_adapter.py': [Errno 2] No such file or directory

But adapting it to use .vscode-server instead of .vscode and ms-python.python-2022.10.1 instead of ms-python.python-2022.10.0 result in:

/gge/venv/bin/python ~/.vscode-server/extensions/ms-python.python-2022.10.1/pythonFiles/testing_tools/run_adapter.py discover pytest -- --rootdir . -s --cache-clear
