性能优化策略
推理框架对比
| 框架 | 优点 | 缺点 | 适用场景 |
|---|---|---|---|
| vLLM | 高性能PagedAttention | 内存占用较高 | 高并发推理 |
| SGLang | 思维模式原生支持 | 生态相对较新 | 复杂推理任务 |
| Transformers | 生态成熟 | 性能中等 | 开发调试 |
| ONNX Runtime | 跨平台优化 | 转换复杂度高 | 生产环境部署 |

model_path,
torch_dtype=torch.bfloat16, # 使用BF16减少内存
device_map="auto", # 自动设备映射
low_cpu_mem_usage=True, # 低CPU内存使用
attn_implementation="sdpa", # 使用SDPA注意力
)
# 启用梯度检查点
if hasattr(model, "gradient_checkpointing_enable"):
model.gradient_checkpointing_enable()

故障排除与调试
常见问题解决方案
| 问题现象 | 可能原因 | 解决方案 |
|---|---|---|
| GPU内存不足 | 模型太大或批处理过大 | 减少批处理大小,使用内存优化 |
| 推理速度慢 | 硬件配置不足 | 升级GPU,使用推理优化框架 |
| 模型加载失败 | 依赖版本不匹配 | 检查Transformers版本≥4.51 |
| API响应超时 | 网络或资源瓶颈 | 调整超时设置,增加资源 |
