Looks like you are facing issues from PyTorch, what’s the pytorch version you are using? And please upgrade Pytorch and try again 
thanks a lot! My print(torch.version) outputs ‘2.3.0+cu121’ . So i will try another version.
hello,siyuan! I have updated the latest torch and torchvision. However, when i’m running the quick start tutorial for e2e model optimization, ‘assertion error: unsupported function type batch_norm.default’ occurred. Is it still the version conflict between TVM and pytorch?
Hi,
Were you able to resolve the issue? I am facing the same Unsupported function type batch_norm.default problem.
not yet,bro. I have figured out the root function which incurred the error. The operator type of newest Pytotch had not been defined in the tvm/src/…code. So it may need a modification?
