Cannot find reference 'models' in '__init__.py'

[renzha-miun]

When I download the code and try to run the examples (ik_example_joints.py) on my MAC Sonoma 14.0. It shows the following error:

Cannot find reference 'models' in 'init.py':32
Unresolved reference 'IK_Engine':32
Cannot find reference 'create_list_chunks' in 'omni_tools.py':92

But, all these files exist in the folders.

How should I fix the error?

You use the previous version (0.8.5.0 by pip) you need to clone the repo to your local.
