the same problem too

@MichaelSolotky @MelLain maybe u can help?

hi i get the next error ``` Log line format: [IWEF]mmdd hh:mm:ss.uuuuuu threadid file:line] msg E0912 13:42:10.953749 86407 dictionary_operations.cc:387] File tmp4artm/vocab.txt does not exist., dictionary will be gathered in random...

so, where i can take `cooc.txt` & `vocab.txt`?

thx `vocab.txt` i should create like [here](https://github.com/bigartm/bigartm-book/blob/master/junk/cooc_dictionary/get_vocab.ipynb)?

and this command `bigartm -c vw.txt -v vocab.txt --cooc-window 10 --cooc-min-tf 5 --write-cooc-tf cooc_tf_ --cooc-min-df 5 --write-cooc-df cooc_df_ --write-ppmi-tf ppmi_tf_ --write-ppmi-df ppmi_df_` create me `cooc.txt`?

cool, it works but i can't whole understand output this command  i hoped that i get values [0...1] but that's not true.

or in this pool, i should take max value and that all? :idk:

ok for example, i will train many models with different num_topics and want to get the best model the main metrics are coherence and perplexity perplexity should down, coherence -...

or maybe can help me with coherence metric which the best choice?
