Speaker Identification in Speaker dilation
Hello,
I am using speaker dilation for finding out number of speaker and time when which speaker has spoken. when i am setting up meta data like following where i am providing num_spearker = num_of_speaker then it is working perfectly and showing correct result.
T1 T2 Speaker_1
T3 T4 Speaker_0  #Correct result
meta = {
    'audio_filepath': an4_audio, 
    'offset': 0, 
    'duration':None, 
    'label': 'infer', 
    'text': '-', 
    'num_speakers': 2, 
    'rttm_filepath': None, 
    'uem_filepath' : None
}
But, when i am initializing num_spearker = None, Its just showing number of speaker=1 and it's initializing all the spoken time speaker to speaker_0.
T1 T2 Speaker_0
T3 T4 Speaker_0 #Wrong result

But, I have worked with speaker dilation few days back and it was working fine for both num_spearker = num_of_speaker, num_spearker = None. But, now it's not showing correct result for num_spearker = None. 
Did this is happening because of new changes in repository? Or do i need to made some changes in tutorial to make it work??
