"'SupervisionSet' object has no attribute 'lazy'"

When running lhotse cut simple I get the above error, which comes from this line:

if all(m is None or m.lazy for m in (supervision_set, feature_set, recording_set)):

Looking at SupervisionSet I don’t see an attribute lazy, so I guess there was a code change that removed it without also modifying the above code?

edit: I fixed it by putting if False so it goes into the non lazy branch and making load_manifest_lazy_or_eager always load non-lazily

it works, thanks

I haven’t tested it with a feature manifest input, I’ll follow up on this.
