How to apply LDA to kmeans

Hello
I clustered kmeans and then filtered out every cluster. And I applied the LDA to each cluster to find out what's inside of it
But on the output
logliklyhood is equal to zero, and no word returned as TOP, and put all the sentences in a zero topic at all.
Does anyone know what the problem is?

    Hi there @m_keshavarz_com, 

     

    Please post your XML and data set (fictionalize data if private) so that we can help you. Without being able to replicate your process, it is difficult to assist you. 

     

    Best,

    Hello
    You are right
    I do not currently have access to my system.
    But I used these operators
    read excel
    select attribute
    process from data
    clustering
    filter example (select cluster 1)
    LDA
      But liklihood becomes zero
    Do you know what the cause is?
