No module named 'transformers.models' while trying to import BertTokenizer

Question

I am trying to import BertTokenizer from the transformers library as follows:

import transformers
from transformers import BertTokenizer
from transformers.modeling_bert import BertModel, BertForMaskedLM

However, I get the following error:

I am using transformers version 3.5.1 because I had a problem with the updated version which can be found here.

Does anyone know how to fix this? Apart from updating the transformers library to its latest version (that will unfortunately cause more errors).

Any help is appreciated!

Answer 1

you can change your code from

transformers.modeling_bert import BertModel, BertForMaskedLM

to

from transformers.models.bert.modeling_bert import BertModel,BertForMaskedLM
