预期行为

我希望在分片初始化期间不会出现任何问题。TGI应该能够正常启动并提供模型服务。

虽然我在这里没有找到已经报告的问题，但我确实发现了一个与vLLM类似的问题。他们甚至刚刚修复了它，所以也许他们的更改可以移植到TGI?

你好，@DrNochi 👋
感谢你报告这个问题，我会@danieldk,他是一个马林Maven！

附注：为什么TGI甚至要回退到使用Marlin内核？据我所知，NVIDIA L4正在使用具有CUDA计算能力8.9的艾达·洛夫莱斯架构，这应该为FP提供硬件支持：NVIDIA CUDA文档。我是不是漏掉了什么？
快速浏览了一下代码，我发现了以下PR #2277,这是最新版本的一部分，基本上“阻止”TGI利用原生FP8支持，通过强制Marlin内核用于CC 8.9。我没有发现任何与这些更改相关的问题或进一步解释。也许@OlivierDehaene可以解释一下这个改变背后的原因？

附注：为什么TGI甚至开始使用Marlin内核？据我所知，NVIDIA L4正在使用具有CUDA计算能力8.9的Ada Lovelace架构，这应该为FP提供硬件支持：NVIDIA CUDA文档。我是不是漏掉了什么？
我们切换到了fbgemm-gpu进行FP8矩阵乘法。然而，它使用了TMA(Tensor内存加速器),而在CC 8.9中并不受支持。
