optimization passes

[ohjunee]

1. why did the onnx optimizer name the factor for optimization "pass"? Is there a reason ??

2. I want to do an impact measurement by layer/operator (fused layer/module) to see how it affects the layer optimized with onnx optimizer, is there any evidence that it improves performance?

It is from the compiler field. Initially a "pass" means traversing the computation graph once, now people use it to describe something like pattern matching.

you might want to use onnxsim, which is a more powerful tool based on onnx optimizer
