title: deeppavlov model train no module found
body: <p>I'm trying to start deeppavlov model training on GoogleColab:</p>
  <pre><code>with configs.ner.ner_ontonotes_bert_mult.open(encoding='utf8') as f:
      nerconfig = json.load(f)
  nerconfig['dataset_reader']['data_path'] = '/content/drive/MyDrive/ntiii/train_test'
  nerconfig['metadata']['variables']['NER_PATH'] = '/content/drive/MyDrive/ntiii/'
  nerconfig['metadata']['download'] = [nerconfig['metadata']['download'][-1]]
  with open('/content/drive/MyDrive/ntiii/train_test/conf.json', 'w', encoding=&quot;utf-8&quot;) as f:
      json.dump(nerconfig, f)
  !python -m deeppavlov train '/content/drive/MyDrive/ntiii/train_test/conf.json'
  </code></pre>
  <p>and getting error:</p>
