Neural net expects 'ivector' features with dimension 100 but you provided 0

Question

I am using gooofy zamia-speech for kaldi's model adaptation for a project.

I followed the steps given by kaldi-adapt-lm to create the model using kaldi-generic-de-tdnn_f-r20190328 model.

When I tested it on a .wav file it showed the following error:

Can someone help me out with it?

Thank you in advance!
