@yzhliu @aca88 @makihiro Hi, I was wondering if you implemented nn.upsample in the graph_pack process. At present, I am trying to implement Unet through VTA, but I met some problems in the graph_pack process. I suspect the reason is nn.upsample or torch.cat. A full description can be found in another post I wrote in [Can Upsample be implemented on VTA in graph_pack?](https://discuss.tvm.apache.org/t/can-upsample-be-implemented-on-vta-in-graph-pack/11635). I'm sorry to bother you now. Since I just got in touch with TVM and VTA, I have encountered this problem, but it has not been solved after a long time of trying. I would like to ask if you have encountered this problem or can you provide some suggestions? I look forward to receiving your suggestions. Thank you!
