How to find the wrong layer quickly when get "return self.data[key] KeyError"

[wikiwen]

Thank you so much to write this nice tool, which helps me a lot to convert models.

But I find it a little difficult to locate accurately where layer or operation raise KeyError, for it always print some unclear information like

return self.data[key] KeyError: 140597801526544

Yesterday I try to convert yolov4 model. It works well after running out = net.forward(input_var) in trans_net function. But it raise KeyError when i try to run print(out). I debug to find it stopped in _cat function, so i guess the point is the operation upon torch.cat. But there's too many cat so that I should expand much time to check all layer upon cat.

So can anyboy tell me what's the correct and quick way to locate problem?

出现这个错误原因一般就是当前层的上一层没做转换，导致blob没加到列表里去，所以找不到
