Dynamic conv operator

I am doing some demo on relay vm and now I encountered a question about dynamic input with uncertain H and W。 This the input format:(batch_size, 32, shape_w, 1)。It may make padding to dynamic, my idea is to pass padding mode until tir level and transform it to tir expr。 But there is a check in tir inputs which is failed, anyone has other ideas about this?Below is the tir expr check. image|690x414
