ظهور الخطأ hashtable keyerror في pandas

أقوم بتحميل بيانات لدي بالشكل التالي:

import pandas as pd
df = pd.read_csv("D:\\data.csv")
df['review']

لكن يظهر لي هذا الخطأ:

reviews_new['review']
Traceback (most recent call last):
  File "<ipython-input-43-ed485b439a1c>", line 1, in <module>
    reviews_new['review']
