I've tried following the DTM tutorial almost line by line to extract topics from a corpus. Using scikit-learn, I can see that there are distinct topics in the corpus, and also that the topics change as a function of time. However, dtm doesn't seem to produce anything that makes sense.
I reproduced your problem, but we have the wrapper for DTM (not our implementation), original code from blei-lab/dtm. You need to create an issue in original repository.
Hi,
I've tried following the DTM tutorial almost line by line to extract topics from a corpus. Using scikit-learn, I can see that there are distinct topics in the corpus, and also that the topics change as a function of time. However, dtm doesn't seem to produce anything that makes sense.

I also get the exact same topics for any other time slice.
Could you please help. Thank you!
