[에러] ModuleNotFoundError: No module named 'transformers.tokenization_bert'

ModuleNotFoundError: No module named 'transformers.tokenization_bert'

from transformers.tokenization_bert import BasicTokenizer
ModuleNotFoundError: No module named 'transformers.tokenization_bert'

transformers version을 2.9에서 4.27로 upgrade하니 위와 같은 에러 발생.

구글링하니, 4.0 이상의 버전에서 발생한다고 하여 3.5로 install 후 해결

pip install transformers==3.5
