@adam-smnk I encountered the same bug on my end.
The root cause for the bug is that `outerDimsPerm` is an optional attribute that could be empty. However, when calling `applyPermutationAndReindexReassoc`, it assumes `outerDimsPerm` to be non-empty. One possible solution is to fill `outerDimsPerm` with default values (`[0, 1, 2, ...]`).
