[TVM Discuss] [Questions] ROCm 'segmentation fault' error when
auto-tuning
Given that it happens after 60 steps, this might not be ROCm but rather the xgboost module. In that case, upgrading to the pre-release or downgrading helps.
https://github.com/apache/incubator-tvm/issues/4953#issuecomment-619255802
That said we also fixed a potential segfault in the AMDGPU llvm codegen last week, so upgrading to the latest TVM master might be a good idea.
Best regards
Thomas

Downgrading to xgboost 0.90 fixed the segmentation fault issue!
Thanks a lot @t-vi

Currently, we use the CUDA schedule (and op) on ROCm:

Hi @t-vi,
I have one follow-up question. I was wondering if you know the location of the file defining the schedule for the ROCm backend conv2d. So far I have checked the file in the link below, but I haven't been able to find the schedule template. I would appreciate any information on this regard.
