Dear All

I’m trying to convert the quantized PyTorch model to the quantized TVM model

is there any way to pass the following error

NotImplementedError: The following operators are not implemented: [‘quantized::layer_norm’, ‘quantized::batch_norm2d’]

Thank you

I also faced the same problem. After doing layer fusion (conv+bn or conv+bn+relu), the error was solved.

normalization layers should be fused to conv/linear layer before deploying.
