IOError: [Errno 13] 權限被拒絕 Pandas

Question

我正在嘗試加載數據集，起初我收到一個錯誤代碼，上面寫着：

pandas.errors.ParserError：標記數據時出錯。 C 錯誤：在源上調用 read(nbytes) 失敗。 試試引擎=“蟒蛇”。

然后我添加了 engine = 'python' 所以我的代碼看起來像這樣以供參考：

import pandas as pd

pd.set_option('display.max_rows',500)
pd.set_option('display.max_columns', 500)
pd.set_option('display.width',1000)
ccr = pd.read_csv('D:/Users/vguevara/ExternalScripts/Colaberry/PythonClass/Consumer_complaints.csv', engine = 'python', sep=',' )
print (ccr)

現在我得到這個錯誤代碼：

IOError: [Errno 13] 權限被拒絕

以前對其他線程的回答都沒有幫助，知道嗎？ 謝謝。

追溯：

IOError: [Errno 13] Permission denied```

Answer 1

您的程序存在權限問題。 你可以試試

sudo chmod o+r <address>

它指向的文件在哪里。

例如，如果您的錯誤是 IOError: [Errno 13] Permission denied: '/usr/local/lib/abc/xyz.txt'

然后運行命令

sudo chmod o+r /usr/local/lib/abc/xyz.txt
