[index-tts]在fastapi里无法运行tts.inter()

一开始以为是 fastapi-queue 的问题，但是现在发现，是在 fastapoi 上无法成功运行 tts.inter()，运行的时候也不报错，而是直接忽略掉，觉得不可思议，因为自己也有用其它模型进行推理，所以百思不得其解。

fastapi_demo.py

import uvicorn
from fastapi import FastAPI, Request
from fastapi.middleware.cors import CORSMiddleware
from my_pro import config
import time
from datetime import datetime, timedelta
import os
import uuid
from indextts.infer import IndexTTS

app = FastAPI()

# 添加 CORS 中间件
app.add_middleware(
    CORSMiddleware,
    allow_origins=["*"],  # 允许所有来源，生产环境中建议指定具体的来源
    allow_credentials=True,# 允许发送凭证（如 cookies）
    allow_methods=["*"],  # 允许所有 HTTP 方法
    allow_headers=["*"],  # 允许所有请求头
)

print("正在加载 index-tts 模型")
IndexTTSModel = IndexTTS(model_dir=os.path.join(config.root_dir, 'indextts/checkpoints'),
                         cfg_path=os.path.join(config.root_dir, 'indextts/checkpoints/config.yaml'))
print("index-tts 模型加载成功")

def index_tts_inference(prompt_path: str, tts_text: str, filename: str):
    """使用 idnex-tts 模型进行推理"""
    file_path = config.temp_dir
    os.makedirs(file_path, exist_ok=True)

    if filename is None or filename == '':
        filename = 'p{}0{}'.format(time.strftime('%y%m%d%H%M%S', time.localtime(time.time())), 0)
        audio_full_path = os.path.join(file_path, filename + '.wav')
    else:
        filename += '-' + str(uuid.uuid1()) + '.wav'
        audio_full_path = os.path.join(file_path, filename)

    audio_path = os.path.join(datetime.now().strftime('%Y/%m'), filename)
    print("正在生成语音...")
    begin = time.time()
    print('audio_full_path:', audio_full_path)
    print(type(IndexTTSModel))
    IndexTTSModel.infer(prompt_path, tts_text, audio_full_path)
    print('audio_full_path 是否存在:', os.path.exists(audio_full_path))
    print("推理文本:", tts_text)
    print(f"音频生成结束，耗时: {time.time() - begin:.2f}s")
    return audio_full_path
