[PyTorch] dyn.strided_slice loses shape information

Hi,

I think that I am having a similar behavior when trying to compile YOLOX-ONNX models in TVM.

%40 = dyn.strided_slice(%0, %8, %9, meta[relay.Constant][7] /* ty=Tensor[(4), int64] */, 
begin=None, end=None, strides=None, axes=None) /* ty=Tensor[(?, ?, ?, ?), float32] */;

Can you support YOLOX?

Thanks!
