re-run mmi_mbr_train.py
Previously, ans.phones
was always the same as ans.labels
after k2.compose
if inner_labels=phones
was requested.
https://github.com/k2-fsa/k2/pull/667 fixed this bug and we need to re-run the training script since the columns of the sparse matrix will be different.
EDITED: ans.phones
will contain more zeros than ans.labels
.
