Error: illegal mode: lose input #87

Closed mryndzionek closed 1 year ago

mryndzionek commented 1 year ago

While converting an ONNX model I have:

Fatal: Cannot import onnx model, got exception from ONNX: illegal mode: lose input onnx::Concat_296

I think it has something to do with the Identity operator. Help with solving this is greatly appreciated.

Which onnx version did you imported? CONNX supports from 1.5 to 1.11. The latest verion is working in progress.

mryndzionek commented 1 year ago

Okay, fair enough. The version I used is 1.12.0.

mryndzionek commented 1 year ago

I converted to 1.11, but still same error.

If you don't mind, Please provide these info:

The model you used
The command you run
Stack trace if available
Version(commit hash) of onnx-connx and connx

I'm really sorry, I think I've sent the wrong error message (from another ONNX compiler). I was testing many compilers/converters in last few weeks, but actually none of them was able to convert/compile my model, so I'm attaching the model: model_1.onnx.tar.gz I think the main problem is that, as Netron is showing, the Identity layers are unconnected. Let me know if you have more insight.
