To run the pre-commit checks locally, you can follow below steps:

1. Ensure that default python is python3. In sonic-mgmt docker container, default python is python2. You can run
   the check by activating the python3 virtual environment in sonic-mgmt docker container or outside of sonic-mgmt
   docker container.
2. Ensure that the pre-commit package is installed:

sudo pip install pre-commit

3. Go to repository root folder
4. Install the pre-commit hooks:

pre-commit install

5. Use pre-commit to check staged file:

pre-commit

6. Alternatively, you can check committed files using:

pre-commit run --from-ref <commit_id> --to-ref <commit_id>

Hi @bingwang-ms I do see There is a cross-feature dependence. File: tests/snmp/test_snmp_interfaces.py, import module: tests.platform_tests.counterpoll.counterpoll_helper

how community deal with such problem , as I need already created function from counterpoll and do not want to duplicate or break existing logic. Can you share some example? Thank you in advance.
