'NoneType' object has no attribute 'items'

I got this error on C1 / W1 exercice
import pandas as pd
import csv

df = pd.read_csv(’./womens_clothing_ecommerce_reviews.csv’

Make sure to run this command:

!aws s3 cp s3://dlai-practical-data-science/data/raw/womens_clothing_ecommerce_reviews.csv ./womens_clothing_ecommerce_reviews.csv

It is in the cell above.

I just stopped and restarted the Jupiter notebook, and things were fine - may be an environment issue,
