EKS Circular import #139
Description
Hi, I am trying to run the Pose-app locally on my GPU. I followed the pose-app documentation and after some troubleshooting with lightning and numpy versions, when I finally call lightning_app run app app.py it gives me this error with EKS circular import:
`(LIGHTNING) khoj@lambda:~/S1DZ/Pose-app$ lightning_app run app app.py
/home/khoj/miniconda3/envs/LIGHTNING/lib/python3.10/site-packages/lightning/fabric/init.py:41: pkg_resources is deprecated as an API. See https://setuptools.pypa.io/en/latest/pkg_resources.html. The pkg_resources package is slated for removal as early as 2025-11-30. Refrain from using this package or pin to Setuptools<81.
A newer version of lightning is available (2.5.5). Would you like to upgrade? [Y/n]: n
Your Lightning App is starting. This won't take long.

ImportError: cannot import name 'EKSConnector' from partially initialized module 'eks' (most likely due to a circular import) (/home/khoj/miniconda3/envs/LIGHTNING/lib/python3.10/site-packages/eks/init.py)`
My guess is that this is happening because eks.py is the name of the file AND the package 'EKS'.
Also, are most of the requirements out-dated? It was difficult to install the pose-app and the documentation alone is really not enough. To make sure it was not a local issue, I also tried installing it on GitHub-codespaces, but the identical circular import error exists there too.
