deeppavlov model train no module found

Question

I'm trying to start deeppavlov model training on GoogleColab:

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="utf-8") as f:
    json.dump(nerconfig, f)
!python -m deeppavlov train '/content/drive/MyDrive/ntiii/train_test/conf.json'

and getting error:

ModuleNotFoundError: No module named 'bert_dp'

My code is based on http://docs.deeppavlov.ai/en/master/features/models/squad.html.

Please help me to solve this problem

Please make sure that you've installed all the model requirements by running

!python -m deeppavlov install '/content/drive/MyDrive/ntiii/train_test/conf.json'
