Static quantization of TransPose model in PyTorch? NotImplementedError: Could not run ‘aten::add.out’

[MukeshNarendran]

I am trying to do a static quantization of the transpose a4 model in PyTorch but I run into this error. It's coming from the aten::add.out operation. How can I modify this in the pre-trained model to make it suitable to test quantization? Thanks

NotImplementedError: Could not run ‘aten::add.out’ with arguments from the ‘QuantizedCPU’ backend. This could be because the operator doesn’t exist for this backend, or was omitted during the selective/custom build process (if using custom build).
