no transcription results

os: windows 11
faster whisper: 0.7.0

When the input audio is an np array, there are no error messages, but there are also no transcription results. Through my debugging, I found that the statement for segment in segments: was not executed

this is my code:

import asyncio
import io
import json
import wave
import pyaudio
import websockets
from faster_whisper import WhisperModel
import os
import numpy as np
import sounddevice as sd


stream = sd.OutputStream(samplerate=16000, channels=1)

stream.start()

os.environ["KMP_DUPLICATE_LIB_OK"]  =  "TRUE"


def initWhisperModel():
    model_size = "tiny"
    model = WhisperModel(model_size, device="cpu", compute_type="int8", num_workers=8, local_files_only=True)
    return model

def write_wav(out_path, audio_data):
    wf = wave.open(out_path, 'wb')
    wf.setnchannels(1)
    p = pyaudio.PyAudio()
    wf.setsampwidth(p.get_sample_size(pyaudio.paInt16))
    wf.setframerate(16000)
    wf.writeframes(audio_data)
    wf.close()

async def process_audio_data(audio_frame, websocket):
    # print(type(audio_frame))
    # print(audio_frame)
    segments, info = model.transcribe(audio_frame, beam_size=5, language="zh", initial_prompt="转录成简体中文",
                                      vad_filter=True,
                                      vad_parameters=dict(min_silence_duration_ms=500))
    # print(type(segments))
    # print(segments)
    for segment in segments:
        print("11112")
        message = json.dumps({"text": segment.text})
        await websocket.send(message)

async def receive_audio_data(websocket, path):
    try:
        async for message in websocket:
            if isinstance(message, bytes):
                audio_data = np.frombuffer(message, dtype=np.float32)
                await process_audio_data(audio_data, websocket)

    except websockets.ConnectionClosed:
        print("WebSocket connection closed.")

model = initWhisperModel()
start_server = websockets.serve(receive_audio_data, 'localhost', 8765, subprotocols=["binary"], ping_interval=None)
asyncio.get_event_loop().run_until_complete(start_server)
asyncio.get_event_loop().run_forever()

Here is the console output when I ran the code.
