WebPyTorch’s biggest strength beyond our amazing community is that we continue as a first-class Python integration, imperative style, simplicity of the API and options. PyTorch 2.0 offers the same eager-mode development and user experience, while fundamentally changing and supercharging how PyTorch operates at compiler level under the hood. WebJul 8, 2024 · This is “blocking,” meaning that no process will continue until all processes have joined. I’m using the nccl backend here because the pytorch docs say it’s the fastest of the available ones. The init_method tells the process group where to look for some settings.
