+如果您有更高推理性能方面的需求，但上述可选加速项`layer_norm`及`rotary`未能安装成功，或是您所使用的GPU不满足`flash-attention`库所要求的NVIDIA Ampere/Ada/Hopper架构，您可以尝试切换至dev_triton分支，使用该分支下基于Triton实现的推理加速方案。该方案适用于更宽范围的GPU产品，在pytorch 2.0及以上版本原生支持，无需额外安装操作。

+If you require higher inference performance yet encounter some problems when installing the optional acceleration features (i.e., `layer_norm` and `rotary`) or if the GPU you are using does not meet the NVIDIA Ampere/Ada/Hopper architecture required by the `flash-attention` library, you may switch to the dev_triton branch and consider trying the inference acceleration solution implemented with Triton in this branch. This solution adapts to a wider range of GPU products and does not require extra package installation with pytorch version 2.0 and above.
