   @FrozenGene I have this problem too. I'm trying to tune an onnx model by autotvm and auto-schedule, the model runs on GPU mali. Tuning with autotvm passed, but failed with accuracy drop using auto-schedule. Followed the suggestion above to disable pass `CanonicalizeOps` or `AlterOpLayout` can help. By the way, the **batch size is 1** and the opt-level is 3. Hope this info can help to locate the bug. Please let me known if you need any experiments under my environment.
