亚马逊推出 TorchNeuron，正面挑战英伟达软件生态
原标题：Amazon is taking its biggest shot at Nvidia yet with new TorchNeuron dev tool
AI 摘要
AWS 发布 TorchNeuron 开发工具，让基于 PyTorch 的 AI 应用只需改一行配置即可运行在亚马逊自研 AI 芯片 Trainium 上，无需重写代码。亚马逊还计划向 PyTorch 上游贡献代码，移除框架与特定芯片绑定的部分，推动 PyTorch 硬件无关化。此举直接挑战英伟达依靠 CUDA 建立的软件生态优势，若成功将削弱开发者对英伟达硬件的锁定。

On Monday, Amazon Web Services released a tool called TorchNeuron that lets AI startups easily move their AI apps onto Amazon’s AI chip, Trainium. In doing so, Amazon is also taking a direct stab at the the software advantage that has helped Nvidia become the default hardware choice for AI apps, and spurred its rise as AI hardware provider of choice. TorchNeuron works with PyTorch, a free, open-source toolkit that developers use to build, train, and run AI models. It lets AI apps written with Py
