atom无法读取同一目录下的csv

Question

CSV文件和.py文件位于其他目录下的同一目录中。你知道吗

upper_directory
 - lower_directory
    - test.py (where I read the csv file from)
    - student_data.csv

我尝试的是：

import pandas as pd
df = pd.read_csv('student_data.csv')

我得到的是：

Traceback (most recent call last):
  File "/Users/iwasiwas/Desktop/flask_dash_directory/myproject/dashboard/test.py", line 3, in <module>
    df = pd.read_csv("student_data.csv")
  File "/Users/iwasiwas/anaconda3/lib/python3.7/site-packages/pandas/io/parsers.py", line 702, in parser_f
    return _read(filepath_or_buffer, kwds)

FileNotFoundError: [Errno 2] File b'student_data.csv' does not exist: b'student_data.csv'

我如何在不键入完整路径的情况下修复此问题？（它可以与完整的-但我需要让它工作没有我的本地完整路径部署，我不明白为什么它不工作，因为这两个.py文件和.csv文件都在同一个目录。）

谢谢你！你知道吗
