HTK Extractor Bug

[Ananay Wadehra]

While running bob spear tookit, the MFCC extractor worked completely fine however the HTK extractor gave an error :

bob.bio.base@2021-03-15 17:16:38,040 -- ERROR: During the execution, an exception was raised: name 'hkt_file' is not defined

    cepstral_features=self.HTKReader(hkt_file)

NameError: name 'hkt_file' is not defined

By going to the file HTKFeatures.py and changing the typo in line 83 [hkt_file to htk_file], I encountered another error

Do you guys have any idea how to mend this error, I think it has to do with the fact of opening the htk_file, even though it has only data[0] value in it?

I ran 'verify.py  -d voxforge -p energy-2gauss -e htk -a gmm-voxforge -s ubm_gmm --groups {dev,eval}' the following' command in the terminal
