Asset Import Failed: ArgumentOutOfRangeException

[Vinz321]

Hello everyone,
I’m new to Barracuda and Onnx in general and I stumbled upon this error while trying to import a .onnx file.

Parameter name: index

I run onnx.checker.check_model on the model before, afraid it was some model error, and since I’m still new I have no idea how to see what’s wrong, I would appreciate if you could explain me how to avoid this in the future
Thanks in advance!
