How to handle unimplemented Pytorch Tensor Operators using rknn-toolkit2 ?

[pjhool]

When loading Pytorch AI Model using RKNN Toolkit2 , the following Error logs occurred.

How to fix the pytorch Exception?

How to replace unimplemented operators that RKNN doesn't support

Let us know how to implement custom Pytorch tensor Operators?
