5 years ago Hello, not sure of the nature of the problem. What exact message do you get, when you try the 'write_mat(...)' with the 'key' in it?
The problem seems to be here : https://github.com/vesis84/kaldi-io-for-python/blob/master/kaldi_io/kaldi_io.py#L476 And we need to figure out how to fix it. (Maybe you need to cast the key to some type, or something?)
Hi, I'm working with python 3.5.2, and I am using a virtualenv to run kaldi_io. I'm trying to use this sample:
import kaldi_io ark_scp_output='ark:| copy-feats --compress=true ark:- ark,scp:data/feats2.ark,data/feats2.scp' with kaldi_io.open_or_fd(ark_scp_output,'wb') as f:
for key,mat in dict.iteritems():kaldi_io.write_mat(f, mat, key=key)My dict is a csv file, such that the first column is utt-id, and the 2nd column is the feature. This feature is in a 2-D (1x1) numpy matrix format. I have 2 problems: a) In using key, string type is not supported. Since that is an optional argument, I just didn't pass it. But I know it will be important.
b) In using open_or_fd, I'm getting the following error: RROR (copy-feats[5.4.176~1-be967]:Read():kaldi-matrix.cc:1616) Failed to read matrix from stream. : Expected "[", got "

Am I doing something wrong?
