'Error parsing message' when accessing TopicKernelScore score tracker values.

[Chemoday]

@MichaelSolotky @MelLain
Hello. I'm getting this error when trying to access TopicKernelScore stats. I think that problem related with the size of the document corpus. I have 13k documents in my collection and this bug occurs when document corpus is greater than 1500 documents (e.g lines in vw.txt)

project with 1500 documents:
Project: bugged_model.zip
All other metrics is working fine with any size of documents corpus

code:

import artm
batches_folder = 'batches/'
data_path='vw.txt'


batch_vectorizer = artm.BatchVectorizer(data_path=data_path,
                                        data_format='vowpal_wabbit',
                                        target_folder=batches_folder)

dictionary = artm.Dictionary()
dictionary.gather(data_path=batches_folder)
topic_names = ["Topic_"+str(i) for i in range(30)]
model = artm.ARTM(topic_names=topic_names,
                  num_topics=30,
                  dictionary=dictionary)
model.scores.add(artm.PerplexityScore(name='PerplexityScore', dictionary=dictionary))
model.scores.add(artm.TopicKernelScore(name='TopicKernelScore',
                                       probability_mass_threshold=0.07))

model.fit_offline(batch_vectorizer=batch_vectorizer,
                              num_collection_passes=40)
print(model.score_tracker['PerplexityScore'].value)
print(model.score_tracker['TopicKernelScore'].average_contrast)
print(model.score_tracker['TopicKernelScore'].average_purity)

Trying to find the cause.
I assume, there is something with anaconda's python interpreter, cos everything works fine on my laptop.
