I always interpretedallow_in_graphas that the annotated function or module should be part of the graph as acall_functionorcall_module. Herehttps://pytorch.org/docs/stable/torch.compiler_fine_grain_apis.htmlit's described as The annotated callable goes as is in the TorchDynamo graph. For exa...
@Chilleeand I were discussing what it would take to getallow_in_graphto work in more situations. Here is an accounting of some situations which we thought of: NN module inputSupport nn.Module arguments for the function to torch.compiler.allow_in_graph#138786 Local functions that close over ...
Python 中的 if/else 编译为字节码后是 POP_JUMP_IF_FALSE 这类条件跳转 (JUMP_IF) 指令,它们在 TorchDynamo 中会引入 Graph Break,触发子图编译 (subgraph compile)。 首先出栈一个元素,即 TensorVariable(lt),然后把附加在其上的 Guard 聚合到 Output Graph 中,最重要的地方是 symbolic_convert.py#L262-...
Dynamo刚开始gm.code可能看起来不是那么直观,所以我们顺便print一下gm.graph。可以注意到两个点。 # After Dynamo# After pre_grad_passes>>print(gm.code)defforward(self,L_x_:torch.Tensor,L_b_:torch.Tensor):l_x_=L_x_l_b_=L_b_lin_w=self.lin_w(l_x_);l_x_=Nonebuf0=lin_w+l_b_;l...

Well, no, we have an Inductor and Triton (and an in-progress AOTAutograd) cache which in principle can cache all of the cubin's that are generated by torch.compile. Most of the time, you can rely on this to reduce startup cost to Dynamo tracing the model only. However, the caches ...

Torch Dynamo会解释运行f的Python Bytecode,捕捉到对应FX Graph。虽然FX Graph是以图的形式存储的,Pytorch还是提供了一些方法, 导出可读,甚至可以丢回给Pytorch去跑的Python Function。(不然估计Upstream Developer没法debug了,Dynamo里那么多if) defforward(self,arg0_1:"f32[32, 512, 1024]"):floor:"f32[32, ...
