Running pytest on Charcoal-SE/Smokedetector under scalene fails

[micsthepick]

Describe the bug
Pytest cannot run due to below error(s):

To Reproduce
Steps to reproduce the behavior:
(tested in WSL2) - Setup a conda env with scalene, clone github.com:charcoal-se/smokedetector.git, pip install -r requirements.txt, and run the following command (modified from a CI yaml) scalene --profile-all -m pytest -W default::Warning --cov=chatcommunicate --cov=findspam --cov=globalvars --cov=spamhandling --cov=datahandling --cov=chatcommands --cov=helpers -n 3 --dist loadgroup --timeout=300 test

Please include a minimum working example if at all possible.

Expected behavior
Runs like as if I'd replaced scalene --profile-all with just python.

Screenshots
If applicable, add screenshots to help explain your problem.

Desktop (please complete the following information):

• OS: Widows 11 Education
• Browser Firefox
• Version:

wsl --version
WSL version: 2.2.4.0
Kernel version: 5.15.153.1-2
WSLg version: 1.0.61

If you have not yet tried with the repository version (python3 -m pip install git+https://github.com/plasma-umass/scalene), please try that before reporting.
(sidenote this may be more helpful at the top of the issue template) - replicates with latest.

Additional context
SmokeDetector can take a while to clone (not too long), so if you think that this might be solvable without cloning it, I'd certainly recommend investigating that way.

possibly related: #82

... and what makes me think so, is the error from scalene:

Scalene: could not find input file /home/mike/sources/SmokeDetector/-u

[emeryberger]

Can you try putting --- after the Scalene flag(s) and before pytest?

[micsthepick]

@emeryberger still reproduces with the following: scalene --profile-all --- -m pytest -W default::Warning --cov=chatcommunicate --cov=findspam --cov=globalvars --cov=spamhandling --cov=datahandling --cov=chatcomm ands --cov=helpers -n 3 --dist loadgroup --timeout=300 test

[micsthepick]

just in case I needed to put -m pytest before the ---, the following doesn't work either:

scalene --profile-all -m pytest --- -W default::Warning --cov=chatcommunicate --cov=findspam --cov=globalvars --cov=spamhandling --cov=datahandling --cov=chatcomm
ands --cov=helpers -n 3 --dist loadgroup --timeout=300 test
