Error message

[omnivoice-cpp] ERROR: model_path is required\n

What it means

omni_load() rejects the call because model_path is NULL or empty (return code 1). Pure argument validation before ov_init: the OmniVoice main model path is mandatory. ggml backend loading (ggml_backend_load_all) has run, but nothing else.

Solutions

1. Configure a valid model_path in the backend options.
2. Add a Go-side guard for empty strings before the FFI call.

Example fix

// before
rc := C.omni_load(C.CString(""), codec, 1, 0)
// after
if modelPath == "" { return errors.New("omnivoice-cpp: model path required") }
rc := C.omni_load(C.CString(modelPath), codec, 1, 0)

if strings.TrimSpace(modelPath) == "" {
    return errors.New("omnivoice-cpp: model_path is required")
}

When it happens

Trigger: Calling omni_load("", codec, use_fa, clamp_fp16) — model path unset in the backend configuration or a nil pointer passed from Go.

Common situations: LocalAI config for omnivoice-cpp missing the model file key; template path not expanded; caller passes empty options struct.
