NameError: name 'pd' is not defined？

Question

import pandas as pd
from sklearn.tree import DecisionTreeClassifier
from sklearn.model_selection import train_test_split
from sklearn.model_selection import GridSearchCV
from sklearn.model_selection import cross_val_score
import matplotlib.pyplot as plt

 

data = pd.read_csv(r"C:\work\learnbetter\micro-class\week 1 DT\data\data.csv")

 

为什么还是会报错？
