@woojinnn 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?. I have been confused here for a long time. I want to know if you have encountered this problem or can you offer some suggestions? Thank you.
