Fish Speech backend using ROCM doesn't work

LocalAI version:
localai/localai:master-gpu-hipblas
sha256:f3ff922777a09ec7f63093df7482ebb15d3f94c0f8611d49143fe455b4f7144d

Environment, CPU architecture, OS, and Version:
I'm doing this on unraid 7.3, using portainer.
AMD Ryzen 9 5900X
Radeon AI PRO R9700
Local AI is setup using distribution mode with nodes.

Describe the bug
I tried to use the fish speech backend and this is the error I get failed to route model with internal loader: routing model fishaudio/s2-pro: loading model fish-speech-s2-pro: loading model fishaudio/s2-pro on node rocinante-worker: Failed to load model: No module named 'fish_speech.inference_engine'

this is the docker log

when I try and view the trace for details and click backend log it just has

Model not loaded on any worker

fish-speech-s2-pro isn't currently loaded on any node in the cluster. Check the Nodes page to see which models are running where.

To Reproduce
I try and create a TTS with the fish-speech backend, I get this error

Expected behavior
For it to work

Start with /backends/rocm-fish-speech/backend.py around LoadModel line 201 and inspect how fish_speech.inference_engine is provided in the reported image. Reproduce the model-loading failure in the distribution setup and verify that Fish Speech loads without the ModuleNotFoundError.
