Training with UbuntuCorpusTrainer fails

[AlkisPis]

It seems I can't train the chatbot with the UbuntuCorpusTrainer. I tried multiple times and, after the first time, in which the trainer downloaded the TGZ file and extracted the TSV files, from thereon I was always receiving the following info: INFO:chatterbot.chatterbot:File is already downloaded INFO:chatterbot.chatterbot:File is already extracted Then the script was stopped responding.

Questions:

1. What could the problem be?
2. The file 'Ubuntu_dialogs.tgz' , which I managed to download myself, contains thousands of TSV files. Where have they been extracted to or converted to ands stored as YML? They can't be found under the 'chatterbot_corpus' folder or anywhere else.
