из pytorch_transformers ModuleNotFoundError: нет модуля с именем 'utils'

Question

Я сталкиваюсь с этой ошибкой при использовании pytorch_transformers в среде Colab после установки Anaconda и ее активации. Я нашел аналогичную проблему в https://github.com/huggingface/transformers/issues/1705, но у меня она не работает. Спасибо за вашу помощь!

!pip install transformers
!pip install simpletransformers
!pip install pytorch-transformers

os.environ['PYTHONPATH'] = "/usr/local/bin/python"

sys.path.append('/usr/local/lib/python3.6/site-packages/')

!conda --version
!conda update -n base conda
!conda install -q -y --prefix /usr/local -c conda-forge tqdm
!conda create -n transformers tqdm
!source activate transformers
