Tesla P40不支持 flash_attn pipline 推理报错

```python
from lmdeploy import pipeline, TurbomindEngineConfig
from lmdeploy.vl import load_image

pipe = pipeline(
'/home/workspace/model/internlm-xcomposer2d5-7b',
backend_config=TurbomindEngineConfig(tp=4)
,model_name='yinhe-vl-chat'
)
image = load_image('/home/workspace/123.png')

response = pipe(('describe this image', image))
print(response.text)
```

我要怎样关闭它，不使用 flash_attn 加速
