Different behaviour with or without the pre-commit hook (reportAttributeAccessIssue)

[ReHoss]

Hi there,

When running pre-commit run with the environment given below, I get this error

error: "run_data_generator" is not a known attribute of module "examples.python_scripts.generating_trajectory_data.trajectory_generator"(reportAttributeAccessIssue)

while running pyright does not return any error.

Could you explain why this behaviour is observed?

should your import be this?

from control_dde.examples.python_scripts.generating_trajectory_data import trajectory_generator

if you could share a repository to reproduce this issue, that'd be a great help :)

This is happening to me too. Driving me nuts
