🚀 The feature, motivation and pitch This RFC proposes an enhancement to torch.compile to improve its backend agnosticism. The goal is to enable a more seamless experience for users working with devices that may not be well-supported by t...

The contract between torch.compile and custom backends doesn't seem to include options? See also https://pytorch.org/docs/main/torch.compiler_custom_backends.html :A backend function has the contract (gm: torch.fx.GraphModule, example_inputs: List[torch.Tensor]) -> Callable....
torchserve Custom handlers TorchServe通过定义handler来处理模型的加载、预处理、推理和后处理。handler通常继承自BaseHandler类,并重写initialize、preprocess、inference和postprocess等方法。如下面代码所示,与Triton Python Backend有些类似。 复制 fromts.torch_handlerimportTorchHandler ...
本文对应第一篇,主要介绍torch.fx和基本使用方法。废话不多说,直接开始吧! 什么是Torch.FX torch.fx是Pytorch 1.8出来的一套工具或者说一个库,是做python-to-python code transformation,大意就是可以把pytorch中的python前向代码转换为你想要的样子,官方介绍如下: ...
如下的custom_backend即自定义的编译逻辑。torch.compile 会把对应的 torch 代码 trace 成 fx.GraphModule 对象,然后传入 custom_backend 函数,这样你就可以根据 fx.GraphModule 自定义编译逻辑,生成一个自定义的函数,返回给 torch.compile。下面例子中的 opt_model 第一次执行时,会触发custom_backend 执行,获取一个...
