Pseudo-labelling librispeech_asr (train.360): KeyError `train-360` when not streaming.

[guynich]

When not streaming this line results in KeyError train-360. The pseudo-labelled dataset was not saved after hours of compute.

I think this KeyError might be caused by this code line that changes the split name.

My bash script uses the Librispeech_asr split name train.360 as defined here.

I commented out code line and my bash script ran to completion.

e.g.:

# make the split name pretty for librispeech etc
# split = split.replace(".", "-").split("/")[-1]
