Question

在Windows 8中，脚本运行正常。在我将脚本和data.csv移动到我的mac中后，我不断收到错误：＆＃34; pandas.io.common.EmptyDataError：没有要从文件中解析的列。＆＃34;

脚本和数据与

位于同一文件夹中

"/Users/myname/Downloads/test/testimport.py"
"/Users/myname/Downloads/test/test2.csv"

我已经尝试了很多文件位置来阅读csv，但没有任何作用。

file_loc = "../test/test2.csv"
# as well as "../test2.csv", "/test2.csv", "/Users/myname/Downloads/test/test2.csv"

import pandas as pd
df = pd.read_csv(file_loc)
exp_mat = df.as_matrix()
print exp_mat

我如何在这里阅读csv？这是错误的位置问题还是mac中的csv文件类型不兼容？

这是OS X El Capitan。完整错误是

h143% python testimport.py
Traceback (most recent call last):
  File "test_importexcel.py", line 24, in <module>
    df = pd.read_csv(file_loc)
