python - IO错误: [Errno 13] Permission denied Pandas

Question

我正在尝试加载数据集，起初我收到一个错误代码:

pandas.errors.ParserError: Error tokenizing data. C error: Calling read(nbytes) on source failed. Try engine='python'.

然后我添加了 engine = 'python' 所以我的代码如下所示以供引用:

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)

现在我收到此错误代码:

IOError: [Errno 13] Permission denied

之前对其他线程的回答都没有帮助，知道吗？谢谢。

Answer 1

您的程序存在权限问题。你可以尝试一下

sudo chmod o+r <address>

它指向的文件在哪里。

例如，如果您的错误是IOError: [Errno 13] 权限被拒绝: '/usr/local/lib/abc/xyz.txt'

然后运行命令

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