Error when working with the naiveBayesClassifier library, how to solve the problem ImportError: No module named 'ExceptionNotSeen?

Question

Python

Hello everyone, now I'm trying to figure out the naiveBayesClassifier library and trying it on an example from Github here .
So here is the actual code:

from naiveBayesClassifier import tokenizer
from naiveBayesClassifier.trainer import Trainer
from naiveBayesClassifier.classifier import Classifier

newsTrainer = Trainer(tokenizer)

newsSet =[
    {'text': 'not to eat too much is not enough to lose weight', 'category': 'health'},
    {'text': 'Russia try to invade Ukraine', 'category': 'politics'},
    {'text': 'do not neglect exercise', 'category': 'health'},
    {'text': 'Syria is the main issue, Obama says', 'category': 'politics'},
    {'text': 'eat to lose weight', 'category': 'health'},
    {'text': 'you should not eat much', 'category': 'health'}
]
for news in newsSet:
    newsTrainer.train(news['text'], news['category'])

newsClassifier = Classifier(newsTrainer.data, tokenizer)

classification = newsClassifier.classify("Obama is")

print(classification)

I imported the library, did what was necessary. I googled the error "ImportError: No module named 'ExceptionNotSeen'", but it did not lead to a significant shift.

Traceback (most recent call last):
File "/Users/YouTube/PycharmProjects/neturalnetw/naive.py", line 7, in

I assume that the problem is directly in the installed from naiveBayesClassifier library, but I still can’t solve it. I would be very happy to help you with this issue.
