Autoscheduler on mask rcnn raises "no task" error

[comaniac]

From the error message it seems due to the dynamic model? But this issue should be resolved by this issue. Are you using the latest TVM?

Autoscheduler and VM

@merrymercy @comaniac I’m interested in auto tuning MaskRCNN on GPU via Ansor. This is a dynamic model so VM is required. But I think workload to each convolution and dense layer should be fixed, so I think it should be feasible to extract tasks from it. Does that sound reasonable? If lack of support for VM is simply a missing feature due to limited resources, I’m happy to take on it. I think MaskRCNN is interesting for Ansor because in addition to large number of conv layers, it also has a l…
