alexwong commented on issue #4497: [Relay] Add a PyTorch to Relay Parser URL: https://github.com/apache/incubator-tvm/pull/4497#issuecomment-584303447 > @alexwong It seems you have problems with alexnet, vgg and mobilenet v2 on cuda. In my refactored version, I have no problem with these three. Have a look and try my script below. You can parse the module in two ways and compare the difference. > https://github.com/masahi/torchscript-to-tvm/blob/master/torchvision_test.py#L51-L60 > > I guess the issue is in dtype or optional arguments handling in your op conversions. I've prepared [a branch](https://github.com/masahi/tvm/tree/torch-refactor) for the refactoring PR based on your current implementation, and I can reproduce errors on alexnet, vgg and mobilenet v2. > > The difference between this branch and the implementation at `torchscript-to-tvm` is mostly on op conversion map, that's why I think problems are there. Okay, will check it out. I was assuming the vgg and alexnet errors were due to the topi implementation of one of the adaptive poolings as it didn't seem like any other frontend used these. If it's in op conversion though, that's an easier fix.
