[mlpack] Error with hmm_viterbi when using gmm hmm

[Mohamed Hassan]

Hi, 

Am trying to use hmm_viterbi with a model i previously created using hmm train, but i keep getting this error:

terminate called after throwing an instance of 'boost::archive::archive_exception'
what(): input stream error
Aborted (core dumped)

I used the following command :
$ hmm_viterbi -i S2Training.csv -m S2Model.xml -o S2_Trainging_labels_GHMMlikely_based_on_S2Model.csv -v

And the model was generated successfully using the following command:
$ hmm_train -i S2Training.csv -t gmm -g 3 -l S2Training_labels.csv -n 6 -v -o S2_Model.xml


Your help is deeply appreciated,
Thanks in advance,
