DUMMY operations, confusing

fostiropoulos opened this issue · comments

I am using torch-xla-nightly (although the same issue exists for 1.7) and following the multiprocessing tutorial structure provided by the documentation. I use tensorflow 2.4 and tensorboard 2.3

Some operations are confusing as to what they mean. Example:

Specifically the dummy operations DUMMY_BEFORE_HLO_PASSES , they seem to be related to some internal process that I couldn't find documented anywhere.

The new behavior is related to this PR:
tensorflow/tensorflow@9dc5df5

@qiuminxu I haven't been able to verify, is this resolved by the PR?
