I got output after running the programme. Output of in file have same word in each topic. I should should change to time by time. while i run it on news dataset. I want to share my output here.

I am also sharing a gamma distribution here.

input_directory=../../input/de-news
corpus_name=de-news
dictionary_file=None
number_of_documents=9800
number_of_topics=10
truncation_level=1000
vocab_prune_interval=2
snapshot_interval=10
batch_size=100
online_iterations=98
tau=64.0
kappa=0.75
alpha_theta=0.1
alpha_beta=1000.0

I want to know how to evaluate this output. and why word is not changing over time here?
