Я довольно плохо знаком с Python и слежу за руководством по созданию wordcloud на основе файла отзывов клиентов.Ссылка на учебник: https://towardsdatascience.com/detecting-bad-customer-reviews-with-nlp-d8b36134dc7e

from wordcloud import WordCloud, STOPWORDS
import pandas as pd

# read data
reviews_df = pd.read_csv("Hotel_Reviews3.csv")
# append the positive and negative text reviews
reviews_df["review"] = reviews_df["Negative_Review"] + reviews_df["Positive_Review"]

# create the label
reviews_df["is_bad_review"] = reviews_df["Reviewer_Score"].apply(lambda x: 1 if x < 5 else 0)

# select only relevant columns
reviews_df = reviews_df[["review", "is_bad_review"]]
reviews_df.head()

Hotel_Reviews3.csv: https://i.stack.imgur.com/8ZGxj.png

Из сообщения об ошибке я бы предположил, что Hotel_Reviews3.csv может не иметь столбца "Positive_Review".Возможно, соответствующая запись таблицы обрезана или имеет пробелы, так что она не соответствует "Positive_Review".
