I am currently using "transformers" with a version of 4.26.0...i would like to know how to rectify the following module issue...here is the code

import pandas as pd
from ast import literal_eval

from cdqa.utils.filters import filter_paragraphs
from cdqa.utils.download import download_model, download_bnpp_data
from cdqa.pipeline.cdqa_sklearn import QAPipeline

Download data and models

download_bnpp_data(dir=r'C:\Users\04647U744\Desktop\exp')
download_model(model='bert-squad_1.1', dir=r'C:\Users\04647U744\Desktop\exp')

Loading data and filtering / preprocessing the documents

df = pd.read_csv(r'C:\Users\04647U744\Documents\Github\CASH_sfaidebtreducer_WSP\data\paragraphs.csv',
converters={'paragraphs': literal_eval})
df = filter_paragraphs(df)

Loading QAPipeline with CPU version of BERT Reader pretrained on SQuAD 1.1

cdqa_pipeline = QAPipeline(reader=r'C:\Users\04647U744\Desktop\exp\bert_qa.joblib')

Fitting the retriever to the list of documents in the dataframe

cdqa_pipeline.fit_retriever(df)

Sending a question to the pipeline and getting prediction

query = 'what is round robin assignment rule?'
prediction = cdqa_pipeline.predict(query)

print('query: {}\n'.format(query))
print('answer: {}\n'.format(prediction[0]))
print('title: {}\n'.format(prediction[1]))
print('paragraph: {}\n'.format(prediction[2]))

from cdqa.
