[hts-users:03883] WARNING while speaker adaptive training

[Hea Young Park <lovelyoe.park@xxxxxxxxx>]

Dear all.
 
 I am trying to build HTS with my custom voice and see WARNING "DLUDecompose: Matrix is Singular in /usr/local/HTS-2.2beta/bin/HERest".
 Has anyone seen this and how to fix it ? Please see some snippets below.

 

Best regards.
