I was able to resolve this issue by modifying this line as model.forward = partial(model.forward_dummy)
Then, I faced another issue that I resolved by commenting out this line. Then, I got the whole bunch of warnings line that

TracerWarning: Converting a tensor to a Python boolean might cause the trace to be incorrect. We can't record the data flow of Python values, so this value will be treated as a constant in the future. This means that the trace might not generalize to other inputs!

and finally an error: Floating point exception (core dumped). Not sure what to do at that point

I am also getting the same Floating point exception (core dumped) error. Were you able to resolve it somehow?

I was able to successfully convert it to ONNX by using this -> #89 (comment)
