Skeleton Compatibility Issues with SLEAP Inference Between Mac and NVIDIA GPU Cluster

[pelikanGIS]

I’m encountering a skeleton-related issue when transferring and running inference models between different environments.

Model Training:
I trained a model on my Mac Studio using SLEAP version 1.3.3.
The training data consisted of frames extracted from a video.
Inference works on the [Mac] (although for some movie when I apply inference I get a message about a Semaphore leak #1430) including applying inference to the entire video.

Inference on NVIDIA GPU Cluster:
I copied the trained models to an NVIDIA GPU cluster running SLEAP version 1.4.1a2.
When applying inference to the same video, I get the following error:
ValueError: Found multiple nodes named (name).

Despite this error (expection), the program continues to process approximately 12% of the movie before the process gets killed.

Testing with SLEAP 1.3.3 on the Cluster:
I attempted to run inference on the same NVIDIA GPU cluster using SLEAP version 1.3.3.
This also resulted in a skeleton-related exception, but the program does not process any frames at all.

Questions:
What steps can I take to debug or resolve skeleton-related errors like Found multiple nodes named (name)?

Thanks
