我正试图在Jupyter跑步

import pandas as pd                     
import matplotlib.pyplot as plt          # plotting
import numpy as np                       # dense matrices
from scipy.sparse import csr_matrix      # sparse matrices
%matplotlib inline

但是在加载数据集时

wiki = pd.read_csv('people_wiki.csv')
# add id column
wiki['id'] = range(0, len(wiki))
wiki.head(10)

以下错误仍然存​​在

NameError                                 Traceback (most recent call last)
<ipython-input-1-56330c326580> in <module>()
----> 1 wiki = pd.read_csv('people_wiki.csv')
      2 # add id column
      3 wiki['id'] = range(0, len(wiki))
      4 wiki.head(10)

NameError: name 'pd' is not defined

任何建议赞赏
