Highlights

Bugfix

This patch release fixes a major bug in ASR Bucketing datasets that was introduced in r1.17.0 in PR #6191. Due to this bug, while each bucket is randomly shuffled before selection on each rank, only a single bucket would loop infinitely - without continuing onto subsequent buckets.

Effect: Significantly worse WER would be obtained since not all buckets would be used.

This has been patched and should work correctly in 1.18.1 onwards.
