||||
3. 使用预热端点: `POST /v1/tts-asr/warmup`
|
||||
|
||||
### MPS内存不足
|
||||
1. 使用更小模型: `export TTS_ASR_MODEL_SIZE=tiny`
|
||||
2. 启用量化: `export TTS_ASR_QUANTIZE=true`
|
||||
3. 降低内存限制: `export TTS_ASR_MPS_MEMORY_LIMIT_MB=4096`
|
||||
|
||||
### 音频处理失败

# TTS/ASR macOS适配修复说明
|
||||
|
||||
## 修复概述
|
||||
|
||||
本次修复彻底重构了`backend/tts_asr.py`，针对macOS和Apple Silicon (M1/M2/M3)进行了全面优化。
|
||||
|
||||
## 主要改进
|
||||
|
||||
### 1. 增强的设备检测 (`_detect_device_capabilities`)
|
||||
|
||||
**改进前问题**:
|
||||
- 简单的张量乘法测试不足以验证MPS设备实际可用性
|
||||
- 缺少内存限制检测
|
||||
- Apple Silicon没有特殊处理
|
||||
|
||||
**改进后**:
|
||||
- 使用`DeviceCapabilities`结构化存储设备信息
|
||||
- 更全面的MPS测试（1000x1000矩阵运算）
|
||||
- 自动检测Apple Silicon并调整内存限制
|
||||
- 根据系统内存动态设置MPS内存阈值（默认60%）
|
||||
- 支持设备能力降级（MPS→CPU, CUDA→CPU）
|
||||
|
||||
**验证方法**:
|
||||
```python
|
||||
# 在Python环境中测试
|
||||
from tts_asr import _detect_device_capabilities
|
||||
caps = _detect_device_capabilities()
|
||||
print(f"Device: {caps.device}")
|
||||
print(f"MPS Available: {caps.mps_available}")
|
||||
print(f"Apple Silicon: {_is_apple_silicon()}")
|
||||
```
|
||||
|
||||
### 2. 模型大小选择和量化支持
|
||||
|
||||
**新增环境变量**:
|
||||
- `TTS_ASR_MODEL_SIZE`: 选择Whisper模型大小
|
||||
- `tiny`: 最小模型，最快但准确度较低
|
||||
- `base`: 基础模型，平衡性能和准确度
|
||||
- `small`: 推荐用于Apple Silicon
|
||||
- `medium`: 中等模型
|
||||
- `large`: 大模型，最高准确度
|
||||
- `turbo`: large-v3-turbo (原默认模型)
|
||||
- `auto`: 自动选择（Apple Silicon默认small）
|
||||
|
||||
- `TTS_ASR_QUANTIZE`: 启用INT8量化（减少内存占用）
|
||||
|
||||
**Apple Silicon优化**:
|
||||
- 自动检测并推荐`small`模型
|
||||
- 考虑MPS内存限制选择合适模型
|
||||
|
||||
**验证方法**:
|
||||
```python
|
||||
# 查看推荐的模型大小
|
||||
from tts_asr import _get_recommended_model_size
|
||||
print(_get_recommended_model_size()) # Apple Silicon: "small"
|
||||
```
|
||||
|
||||
### 3. 离线模式支持
|
||||
|
||||
**新增环境变量**:
|
||||
- `TTS_ASR_OFFLINE_MODE`: 启用离线模式
|
||||
- 启动前检查模型是否已缓存
|
||||
- 缓存不存在时优雅失败而非崩溃
|
||||
|
||||
**验证方法**:
|
||||
```bash
|
||||
# 启用离线模式
|
||||
export TTS_ASR_OFFLINE_MODE=true
|
||||
python backend/main.py
|
||||
|
||||
# 检查模型缓存
|
||||
python -c "from tts_asr import _check_model_cached; print(_check_model_cached('openai/whisper-small'))"
|
||||
```
|
||||
|
||||
### 4. 健壮的音频处理
|
||||
|
||||
**改进前问题**:
|
||||
- `librosa.resample`失败时无回退
|
||||
- 缺少音频数据验证
|
||||
|
||||
**改进后**:
|
||||
- `_validate_audio_data()`: 验证音频数据有效性
|
||||
- `_resample_audio_robust()`: 多重回退重采样
|
||||
1. 优先使用`librosa.resample`
|
||||
2. 回退到`torchaudio.transforms.Resample`
|
||||
3. 最后使用NumPy线性插值
|
||||
|
||||
**验证方法**:
|
||||
```python
|
||||
import numpy as np
|
||||
from tts_asr import _resample_audio_robust
|
||||
|
||||
# 测试重采样
|
||||
audio = np.random.randn(16000).astype(np.float32)
|
||||
resampled = _resample_audio_robust(audio, 16000, 48000)
|
||||
print(f"Original: {len(audio)}, Resampled: {len(resampled)}")
|
||||
```
|
||||
|
||||
### 5. 改进的错误处理和降级
|
||||
|
||||
**降级路径**:
|
||||
```
|
||||
MPS推理失败 → 标记MPS不可用 → 清理MPS缓存 → 降级到CPU
|
||||
CUDA推理失败 → 标记CUDA不可用 → 清理CUDA缓存 → 降级到CPU
|
||||
```
|
||||
|
||||
**日志改进**:
|
||||
- 详细记录设备检测过程
|
||||
- 明确标注降级原因
|
||||
- 显示模型大小、量化状态、离线模式等配置
|
||||
|
||||
### 6. 新增API端点
|
||||
|
||||
**GET /v1/tts-asr/config**:
|
||||
```json
|
||||
{
|
||||
"environment": {
|
||||
"TTS_ASR_DEVICE": "auto",
|
||||
"TTS_ASR_MODEL_SIZE": "auto",
|
||||
"TTS_ASR_QUANTIZE": false,
|
||||
"TTS_ASR_OFFLINE_MODE": false,
|
||||
...
|
||||
},
|
||||
"device": {
|
||||
"current": "mps",
|
||||
"mps_available": true,
|
||||
"cuda_available": false,
|
||||
"is_apple_silicon": true,
|
||||
"mps_memory_limit_mb": 8192
|
||||
},
|
||||
"model": {
|
||||
"tts": "hexgrad/Kokoro-82M",
|
||||
"asr_current_size": "small",
|
||||
"asr_recommended_size": "small",
|
||||
"available_sizes": ["tiny", "base", "small", "medium", "large", "turbo"]
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## 环境变量完整列表
|
||||
|
||||
| 变量名 | 说明 | 默认值 | 示例 |
|
||||
|--------|------|--------|------|
|
||||
| `TTS_ASR_DEVICE` | 设备选择 | `auto` | `mps`, `cuda`, `cpu` |

|
||||
| `TTS_ASR_MPS_MEMORY_LIMIT_MB` | MPS内存限制(MB) | `8192` | `4096`, `16384` |
|
||||
|
||||
## macOS使用建议
|
||||
|
||||
### 推荐配置
|
||||
|
||||
**Apple Silicon (M1/M2/M3) 8GB内存**:
|
||||
```bash
|
||||
export TTS_ASR_MODEL_SIZE=small
|
||||
export TTS_ASR_MPS_MEMORY_LIMIT_MB=4096
|
||||
```
|
||||
|
||||
**Apple Silicon (M1/M2/M3) 16GB+内存**:
|
||||
```bash
|
||||
export TTS_ASR_MODEL_SIZE=medium
|
||||
export TTS_ASR_MPS_MEMORY_LIMIT_MB=8192
|
||||
```
|
||||
|
||||
**内存紧张时**:
|
||||
```bash
|
||||
export TTS_ASR_MODEL_SIZE=tiny
|
||||
export TTS_ASR_QUANTIZE=true
|
||||
```
|
||||
|
||||
### 性能优化建议
|
||||
|
||||
1. **首次运行**: 建议不使用离线模式，让模型自动下载
|
||||
2. **后续运行**: 启用离线模式避免网络延迟
|
||||
```bash
|
||||
export TTS_ASR_OFFLINE_MODE=true
|
||||
```
|
||||
|
||||
3. **长期运行服务**: 设置空闲超时自动卸载模型
|
||||
```bash
|
||||
export TTS_ASR_IDLE_TIMEOUT=600 # 10分钟后卸载
|
||||
```
|
||||
|
||||
4. **调试模式**: 查看详细设备检测日志
|
||||
```python
|
||||
import logging
|
||||
logging.getLogger("tts_asr").setLevel(logging.DEBUG)
|
||||
```
|
||||
|
||||
## 验证步骤（非Mac环境）
|
||||
|
||||
由于你不在Mac环境下，可以使用以下方法验证代码逻辑：
|
||||
|
||||
### 1. 代码静态检查
|
||||
```bash
|
||||
# 检查Python语法
|
||||
python -m py_compile backend/tts_asr.py
|
||||
|
||||
# 检查导入
|
||||
python -c "import backend.tts_asr"
|
||||
```
|
||||
|
||||
### 2. 单元测试模拟
|
||||
```python
|
||||
# 模拟Apple Silicon环境
|
||||
import os
|
||||
import platform
|
||||
|
||||
# 模拟Darwin/arm64
|
||||
original_system = platform.system
|
||||
original_machine = platform.machine
|
||||
|
||||
def mock_system():
|
||||
return "Darwin"
|
||||
|
||||
def mock_machine():
|
||||
return "arm64"
|
||||
|
||||
platform.system = mock_system
|
||||
platform.machine = mock_machine
|
||||
|
||||
# 测试Apple Silicon检测
|
||||
from tts_asr import _is_apple_silicon
|
||||
assert _is_apple_silicon() == True
|
||||
|
||||
# 恢复原始函数
|
||||
platform.system = original_system
|
||||
platform.machine = original_machine
|
||||
```
|
||||
|
||||
### 3. 环境变量测试
|
||||
```python
|
||||
import os
|
||||
os.environ['TTS_ASR_MODEL_SIZE'] = 'small'
|
||||
os.environ['TTS_ASR_QUANTIZE'] = 'true'
|
||||
|
||||
# 重新加载模块
|
||||
import importlib
|
||||
import backend.tts_asr
|
||||
importlib.reload(backend.tts_asr)
|
||||
|
||||
from backend.tts_asr import TTS_ASR_MODEL_SIZE, TTS_ASR_QUANTIZE
|
||||
assert TTS_ASR_MODEL_SIZE == 'small'
|
||||
assert TTS_ASR_QUANTIZE == True
|
||||
```
|
||||
|
||||
### 4. API端点测试（需要运行服务）
|
||||
```bash
|
||||
# 启动服务
|
||||
python backend/main.py
|
||||
|
||||
# 测试配置端点（需要API Key）
|
||||
curl -X GET "http://localhost:8001/v1/tts-asr/config" \
|
||||
-H "X-API-Key: your-secret-key-here"
|
||||
|
||||
# 测试状态端点
|
||||
curl -X GET "http://localhost:8001/v1/tts-asr/status" \
|
||||
-H "X-API-Key: your-secret-key-here"
|
||||
```
|
||||
|
||||
## 依赖更新
|
||||
|
||||
已在`backend/requirements.txt`中添加:
|
||||
- `psutil`: 系统内存检测
|
||||
- `torchaudio`: 音频重采样备选方案
|
||||
|
||||
安装新依赖:
|
||||
```bash
|
||||
pip install -r backend/requirements.txt
|
||||
```
|
||||
|
||||
## 向后兼容性
|
||||
|
||||
所有改动保持向后兼容：
|
||||
- 现有API端点未改变
|
||||
- 默认行为与原版一致
|
||||
- 新功能通过环境变量启用
|
||||
|
||||
## 已知限制
|
||||
|
||||
1. **MPS float16**: 在某些操作上可能不稳定，代码默认使用float32
|
||||
2. **8-bit量化**: 仅在CPU和CUDA环境支持，MPS不支持
|
||||
3. **Core ML**: 预留了扩展点但未实现（需要额外依赖）
|
||||
|
||||
## 未来改进方向
|
||||
|
||||
1. 集成Core ML作为备选推理后端
|
||||
2. 支持torch.compile (PyTorch 2.0+)
|
||||
3. 实现模型自动下载的进度显示
|
||||
4. 添加更多音频格式支持
|
||||
|
||||
## 问题排查
|
||||
|
||||
### 模型加载失败
|
||||
1. 检查网络连接
|
||||
2. 尝试关闭离线模式: `export TTS_ASR_OFFLINE_MODE=false`
|
||||
3. 查看详细日志: 设置`logging.getLogger("tts_asr").setLevel(logging.DEBUG)`
|
||||
|
||||
### MPS内存不足
|
||||
1. 使用更小的模型: `export TTS_ASR_MODEL_SIZE=tiny`
|
||||
2. 启用量化: `export TTS_ASR_QUANTIZE=true`
|
||||
3. 降低内存限制: `export TTS_ASR_MPS_MEMORY_LIMIT_MB=4096`
|
||||
|
||||
### 音频处理失败
|
||||
1. 检查音频格式（支持WAV）
|
||||
2. 确保音频采样率≥8000Hz
|
||||
3. 查看日志中的详细错误信息
|

# TTS/ASR 测试指南
|
||||
|
||||
本文档提供完整的测试脚本使用说明，包括单元测试、集成测试和macOS环境模拟测试。
|
||||
|
||||
## 测试脚本概览
|
||||
|
||||
| 脚本 | 位置 | 用途 | 需要后端服务 |
|
||||
|------|------|------|--------------|
|
||||
| `test_tts_asr_unit.py` | `backend/tests/` | 单元测试（设备检测、模型选择、音频处理） | 否 |
|
||||
| `test_tts_asr_integration.py` | `backend/tests/` | 集成测试（API端点、完整流程） | 是 |
|
||||
| `simulate_macos.py` | `backend/tests/` | macOS环境模拟（在非Mac环境测试） | 否 |
|
||||
|
||||
## 快速开始
|
||||
|
||||
### 1. 单元测试（推荐首先运行）
|
||||
|
||||
单元测试不需要实际运行模型或后端服务，测试代码逻辑：
|
||||
|
||||
```bash
|
||||
# 使用pytest运行（推荐）
|
||||
pytest backend/tests/test_tts_asr_unit.py -v
|
||||
|
||||
# 直接运行
|
||||
python backend/tests/test_tts_asr_unit.py
|
||||
|
||||
# 运行特定测试类
|
||||
pytest backend/tests/test_tts_asr_unit.py::TestAppleSiliconDetection -v
|
||||
|
||||
# 运行特定测试方法
|
||||
pytest backend/tests/test_tts_asr_unit.py::TestAppleSiliconDetection::test_is_apple_silicon_on_darwin_arm64 -v
|
||||
```
|
||||
|
||||
### 2. macOS环境模拟测试
|
||||
|
||||
在非macOS环境下模拟Apple Silicon环境：
|
||||
|
||||
```bash
|
||||
# 运行完整模拟测试套件
|
||||
python backend/tests/simulate_macos.py --full-simulation
|
||||
|
||||
# 仅模拟Apple Silicon环境并进入交互模式
|
||||
python backend/tests/simulate_macos.py --apple-silicon
|
||||
|
||||
# 模拟特定设备
|
||||
python backend/tests/simulate_macos.py --device mps
|
||||
python backend/tests/simulate_macos.py --device cuda
|
||||
|
||||
# 运行特定测试
|
||||
python backend/tests/simulate_macos.py --test device # 设备检测
|
||||
python backend/tests/simulate_macos.py --test memory # 内存管理
|
||||
python backend/tests/simulate_macos.py --test model # 模型选择
|
||||
python backend/tests/simulate_macos.py --test audio # 音频处理
|
||||
python backend/tests/simulate_macos.py --test env # 环境变量
|
||||
```
|
||||
|
||||
### 3. 集成测试
|
||||
|
||||
集成测试需要运行后端服务：
|
||||
|
||||
```bash
|
||||
# 1. 启动后端服务（终端1）
|
||||
python backend/main.py
|
||||
|
||||
# 2. 运行集成测试（终端2）
|
||||
# 运行所有测试
|
||||
python backend/tests/test_tts_asr_integration.py
|
||||
|
||||
# 运行特定测试
|
||||
python backend/tests/test_tts_asr_integration.py --test config # 配置端点
|
||||
python backend/tests/test_tts_asr_integration.py --test status # 状态端点
|
||||
python backend/tests/test_tts_asr_integration.py --test warmup # 预热测试
|
||||
python backend/tests/test_tts_asr_integration.py --test tts # TTS测试
|
||||
python backend/tests/test_tts_asr_integration.py --test asr # ASR测试
|
||||
python backend/tests/test_tts_asr_integration.py --test perf # 性能测试
|
||||
|
||||
# 自定义API地址
|
||||
python backend/tests/test_tts_asr_integration.py --url http://localhost:8001 --key your-api-key
|
||||
```

|
||||
### GitHub Actions示例
|
||||
|
||||
```yaml
|
||||
name: TTS/ASR Tests
|
||||
|
||||
on: [push, pull_request]
|
||||
|
||||
jobs:
|
||||
unit-tests:
|
||||
runs-on: ubuntu-latest
|
||||
steps:
|
||||
- uses: actions/checkout@v3
|
||||
- uses: actions/setup-python@v4
|
||||
with:
|
||||
python-version: '3.10'
|
||||
- name: Install dependencies
|
||||
run: |
|
||||
pip install -r backend/requirements.txt
|
||||
pip install pytest
|

|
||||
- name: Run macOS simulation
|
||||
run: python backend/tests/simulate_macos.py --full-simulation
|
||||
```
|
||||
|
||||
### pytest配置
|
||||
|
||||
创建 `pytest.ini`:
|
||||
|
||||
```ini
|
||||
[pytest]
|
||||
testpaths = backend/tests
|
||||
python_files = test_*.py
|
||||
python_classes = Test*
|
||||
python_functions = test_*
|
||||
addopts = -v --tb=short
|
||||
```
|
||||
|
||||
## 故障排查
|
||||
|
||||
### 问题1: 导入错误
|
||||
|
||||
```
|
||||
ModuleNotFoundError: No module named 'backend'
|
||||
```
|
||||
|
||||
**解决方案**:
|
||||
|
||||
```bash
|
||||
# 确保在项目根目录运行
|
||||
cd /path/to/llm-in-text
|
||||
|
||||
# 或设置PYTHONPATH
|
||||
export PYTHONPATH="${PYTHONPATH}:$(pwd)"
|
||||
```
|
||||
|
||||
### 问题2: 后端服务连接失败
|
||||
|
||||
```
|
||||
✗ 无法连接到服务: [Errno 111] Connection refused
|
||||
```
|
||||
|
||||
**解决方案**:
|
||||
|
||||
```bash
|
||||
# 确保后端服务正在运行
|
||||
python backend/main.py
|
||||
|
||||
# 检查端口
|
||||
lsof -i :8001
|
||||
|
||||
# 或使用自定义URL
|
||||
python backend/tests/test_tts_asr_integration.py --url http://localhost:8001
|
||||
```
|
||||
|
||||
### 问题3: 模型未加载
|
||||
|
||||
```
|
||||
⚠ TTS失败（可能是模型未加载）
|
||||
```
|
||||
|
||||
**解决方案**:
|
||||
|
||||
这是预期行为，表示模型需要时间下载。可以：
|
||||
|
||||
1. 等待模型下载完成
|
||||
2. 使用预热端点: `POST /v1/tts-asr/warmup`
|
||||
3. 启用离线模式（如果模型已下载）
|
||||
|
||||
### 问题4: 测试超时
|
||||
|
||||
```
|
||||
httpx.ReadTimeout: timed out
|
||||
```
|
||||
|
||||
**解决方案**:
|
||||
|
||||
```bash
|
||||
# 增加超时时间
|
||||
export TEST_TIMEOUT=300.0
|
||||
|
||||
# 或在测试脚本中修改
|
||||
TEST_TIMEOUT = 300.0 # 5分钟
|
||||
```
|
||||
|
||||
## 最佳实践
|
||||
|
||||
1. **开发时**: 频繁运行单元测试
|
||||
```bash
|
||||
pytest backend/tests/test_tts_asr_unit.py -v --tb=short
|
||||
```
|
||||
|
||||
2. **提交前**: 运行完整测试套件
|
||||
```bash
|
||||
pytest backend/tests/test_tts_asr_unit.py -v
|
||||
python backend/tests/simulate_macos.py --full-simulation
|
||||
```
|
||||
|
||||
3. **部署前**: 运行集成测试
|
||||
```bash
|
||||
python backend/tests/test_tts_asr_integration.py
|
||||
```
|
||||
|
||||
4. **调试时**: 使用详细输出
|
||||
```bash
|
||||
pytest backend/tests/test_tts_asr_unit.py -v -s --tb=long
|
||||
```
|
||||
|
||||
## 测试报告
|
||||
|
||||
生成测试覆盖率报告：
|
||||
|
||||
```bash
|
||||
# 安装coverage
|
||||
pip install pytest-cov
|
||||
|
||||
# 运行并生成报告
|
||||
pytest backend/tests/test_tts_asr_unit.py --cov=backend.tts_asr --cov-report=html
|
||||
|
||||
# 查看报告
|
||||
open htmlcov/index.html
|
||||
```
