[BUG] onnx-simplifier==0.4.25 cannot do shape inference in some onnx about onnx-simplifier

[congyang12345]

I have the same problem, you can try

pip install onnxslim

onnxslim onnx_model slimmed_onnx_model

and the shape can be inferred.

This problem is solved when I degrade onnxsim to 0.4.13, but I still want to ensure why it happens in 0.4.25

Thanks for your issue! Fixed in v0.4.36. Please update onnxsim by pip install -U onnxsim
