Cannot run coqui tts - Error: grpc process not found (image and local docker build)

[blob42]

LocalAI version:

• v2.8.2-cublas-cuda12-ffmpeg
• local docker-compose build with following:

           FFMPEG: true
           BUILD_TYPE: cublas
           CUDA_MAJOR_VERSION: 12
           CUDA_MINOR_VERSION: 3
           GO_TAGS: "tts stablediffusion"
           BUILD_GRPC: true

Environment, CPU architecture, OS, and Version:
docker 24.0.7 on ArchLinux - Linux 6.6.6-zen1-1-zen

Describe the bug
I get the following error when I try to run coqui TTS using the example from documentation I see a grpc connection error. I am using docker so manually running the local-ai tts ... command from the container shows the following detailed error:

To Reproduce
Just pulled or build the v2.8.2 image. For info the inference with cuda works.

Expected behavior
working coqui tts endpoint

[blob42]

I think the reason is me using nvidia based build. the common-env/transformers-nvidia.yml does not contain TTS as a requirement

https://github.com/mudler/LocalAI/blob/9f2235c208b8a490f105774f984aa7225c4642b7/backend/python/common-env/transformers/transformers.yml#L36C1-L36C20

try to build the backend first with this comand make clean and BUILD_GRPC_FOR_BACKEND_LLAMA=ON make GO_TAGS=stablediffusion,tts build or make GO_TAGS=stablediffusion,tts,tinydream build for all the bakends before to run docker, it would be more useful if you could give more details about your worklfow: .env, go and python version, docker-compose.yaml, dockerfile and your ssh comand. after when you have the GO_TAGS rebuild the image simply run docker-compose up --build or docker-compose up -d you ned to setup REBUILD=true and GO_TAGS= tts in your .env file in order to use tts .

I can confirm the grpc backend works by adding the TTS dependency to the nvidia requirements file
