RuntimeError: failed to compute mgcep; error occured in theq

Hello ttslr, thanks for your repo and give me some insight on how to calculate the MCD. However, there is an error I could not figure it out how to handle, saying:

Processing -----------30.wav
theq() : determinant of the normal matrix is too small!
mgcep : Error in theq() at 0th iteration!

Do you have any idea how to solve this problem? Thanks..

Thanks for your attention!
I remembered this problem could be solved if you update your 'pysptk'.

Hope these links can help you:

I have the same question and I update the pysptk 0.1.18 but still have the same question.
The audio is single channel.
