[houaki via TVM Discuss]

hi all,
today, following the pipeline PyTorch -> ONNX -> TVM, I met following errors 
with cuda error code  `CUDA_ERROR_INVALID_PTX` 
![image|690x160](upload://ApHg9ZIxTKIIP9CAVzoO71MvQNC.png) 
The same model, 800X800 can work, but 512x512 reports this error
my env:
cuda10.0
torch 1.4.0
Latest commit for TVM


please, help me, thank you!!!
