Compile onnx model error in pytorch 1.1.0


I use pytorch 1.1.0 and covert the model to onnx. Then I use tvm to compile onnx model, I found this error:

And I add some debug info, I found the op “unsample” cause the " AttributeError: ‘<class ‘tvm.relay.expr.Call’>’ object has no attribute ‘name_hint’"

debug: Floor
debug: Unsqueeze
debug: Unsqueeze
debug: Concat
debug: Cast

I Solve it, It’s pytorch 1.1.0 bug, reinstall pytorch 1.0.1 solve it。


Hi,I meet the same problem.But it can not solve by using pytorch 1.0.1. Any suggestions?Looking forward your reply!


@burness What is your version of tvm?Do you try pytorch1.2 or nightly?
