AssertionError: cycle-free graph violated: partition depends on itself

[Surya-T44]

I have created a classifier model.onnx with 6 classes. I streamlined the model and then tried to partition but I kept getting the error 'AssertionError: cycle-free graph violated: partition depends on itself'. I tried other streamline options (absorb, move) none of them worked. Even tried to remove the individual nodes manually to see if it works, but it keeps giving the same error. Could anyone please help?
