Why are we using "load_segments_rechash" function when loading the segments file? Why are we not using "load_segments", Its causing key error in the pipeline.

[saumyaborwankar]

This is regarding mini_librispeech speech recipe
Line number 254 in eend/feature.py filtered_segments = kaldi_obj.segments[kaldi_obj.segments['rec'] == rec] returns a key error of 'rec' if we use load_segments_recash in line number 149 in eend/kaldi_data.py which can be fixed by using filtered_segments = kaldi_obj.segments[rec] But I'm not really sure if we should change this.
Any help is welcome.
Let me know what to use and when to use. Thanks
