Question

我正在尝试使用pandas read_csv函数读取CSV文件但我不断收到OSError。我尝试了很多不同的修复程序，但似乎都没有。我修复了以前的文件未找到错误但意外得到此错误。这是我使用的代码。请注意我使用Jupyter笔记本作为Anaconda的一部分。

import pandas as pd
import os

curDir = os.getcwd()
#print(curDir)

melbourne_file_path = '..\Downloads\melb_data.csv'
melbourne_data = pd.read_csv(melbourne_file_path) 
print(melbourne_data.describe())

这是我得到的输出/错误：

      7 melbourne_file_path = '..\Downloads\melb_data.csv'
----> 8 melbourne_data = pd.read_csv(melbourne_file_path)
      9 print(melbourne_data.describe())

Answer 1

尝试：

melbourne_file_path = '../Downloads/melb_data.csv'

或

melbourne_file_path = '..\\Downloads\\melb_data.csv'

Answer 2

如果使用Spyder 3.7，请确保第1行显示#!/usr/bin/env python3。有时，如果未激活正确的Anaconda环境，则会创建temp.py文件。 temp.py文件可能未包含#!/usr/bin/env python3。以下两个图像显示了两个文件。第一个缺少第1行的内容，第二个包含修复程序。

without fix

with fix

1）确保使用源激活激活conda环境

2）确保#!/usr/bin/env python3出现在新python文件的第1行

为什么我会得到这个OSError？
