原标题：Google has joined Amazon in attacking Nvidia’s stronghold with AI app developers
AI 摘要
Google 宣布开源 TorchTPU，这是其长期开发的 PyTorch 版本，可让 AI 应用无需重写代码、仅通过配置变更即可运行在 Google 的 TPU 及 Google Cloud 上。此前一天，Amazon 也发布了类似工具 TorchNeuron，支持将 PyTorch 应用迁移至其自研芯片 Trainium 和 AWS。两家公司正联手削弱 Nvidia 在 AI 硬件领域的主导地位，但开发者是否会大规模转向替代芯片仍不确定。

On Tuesday, Google announced that TorchTPU, its long-awaited version of PyTorch, is now available as an open-source project. With this, Google joins Amazon in trying to break Nvidia’s stranglehold on the AI industry, where most AI apps are written by default to run on Nvidia’s chips, or GPUs. PyTorch is the popular open-source toolkit that AI app developers and startups use to build, train, and run AI models. It is, by some accounts, used by 85% of the AI apps. PyTorch was originally developed b
