Hi Kyle! Logs show there is a symlink and we do some path updating in that case to fix issues caused by the symlink we have seen in the past. To confirm is Symlink found at: /home/kyle/Dropbox (GaTech) a symlink? What does it map to if so? When you try this same thing from the command line is it found correct and everything? The equivalent command would be: python -m pytest --collect-only "--rootdir=~/Dropbox (GaTech)/projects/cleo" Finally if it works right from the command line, could you try printing the python path before the erroring import in your conftest.py file? Specifically looking to see if the rootdir is in it as expected or not. The code to do this would be

import sys
print(sys.path)

Hi Eleanor, thanks for getting back.

• Yes, ~/Dropbox (GaTech) is a symlink to ~/GaTech Dropbox/Kyle Johnsen/
• Running the command you gave me (though I had to use $HOME instead of ~) collected all the tests without a problem
• rootdir looks like it was adjusted correctly. sys.path:

  • ['/home/kyle/GaTech Dropbox/Kyle Johnsen/projects/cleo/tests', '/home/kyle/GaTech Dropbox/Kyle Johnsen/projects/cleo', '/home/kyle/.vscode-server-insiders/extensions/ms-python.python-2024.14.1-linux-x64/python_files', '/home/kyle/miniforge3/lib/python312.zip', '/home/kyle/miniforge3/lib/python3.12', '/home/kyle/miniforge3/lib/python3.12/lib-dynload', '/home/kyle/miniforge3/lib/python3.12/site-packages', '/home/kyle/.vscode-server-insiders/extensions/ms-python.python-2024.14.1-linux-x64/python_files', '/home/kyle/.vscode-server-insiders/extensions/ms-python.python-2024.14.1-linux-x64/python_files/lib/python']
    

• I printed sys.executable and it was indeed wrong—/home/kyle/miniforge3/bin/python—using my base conda environment instead of the selected interpreter for this workspace (~/miniforge3/envs/cleo/bin/python)

Go Jackets!

@anthonykim1, looks like the issue here is the right environment is not being selected, this is likely related to the other issues we have seen with conda env activation. This investigation should help solve this issue as well: #24190. Thanks!
