Relative path not working in Pandas python in Jupyter notebook
提问by TutuGeorge
my folder structure is :
我的文件夹结构是：
datasets/file.csv
source/code.ipynb
from within i want to access the file named file.csv.
我想从内部访问名为 file.csv 的文件。
import pandas as pd
data = pd.read_csv("../datasets/file.csv")
This is giving me the error : ParserError: Error tokenizing data. C error: Expected 1 fields in line 68, saw 2
这给了我错误： ParserError: Error tokenizing data. C error: Expected 1 fields in line 68, saw 2
How to access file using relative path in pandas python? I am using Python3.6 with Anaconda in Windows 8.1 with Jupyter notebook.

The ParseError indicates that your error is in parsing the file, not locating and opening it. To verify this, try:
ParseError 表示您的错误在于解析文件，而不是定位和打开它。要验证这一点，请尝试：
test_file = open('../datasets/file.csv')
for line in test_file:
print(line.strip())
This should print out the lines in file.csv.
这应该打印出 file.csv 中的行。
