How to Fix ModuleNotFoundError: No module named ‘transformers.models’

ModuleNotFoundError: No module named ‘transformers.models’ error occurs while trying to import BertTokenizer because you might not have installed the transformers library or are trying to import BertTokenizer incorrectly.

To fix the ModuleNotFoundError: No module named ‘transformers.models’ error, ensure that you have installed the transformers library by running this command: pip install transformers.

Then, import the BertTokenizer like this.

from transformers import BertTokenizer

Here’s an example of how to use the BertTokenizer:

from transformers import BertTokenizer

tokenizer = BertTokenizer.from_pretrained("bert-base-uncased")

text = "This is an example sentence."
tokens = tokenizer.tokenize(text)
token_ids = tokenizer.convert_tokens_to_ids(tokens)

print(tokens)
print(token_ids)

Output

['this', 'is', 'an', 'example', 'sentence', '.']

You must ensure you have the correct import statement and have installed the transformers library before running the code.

That’s it.
