如何在熊猫中读取具有完整路径的csv文件

Question

我在Python中得到了这个代码：

import pandas as pd
from pathlib import Path

path_1 = Path('C:/Users/wotesi/Documents/Cloud/Documents/Python/Programmas/panda/')
print(path_1)
full_path = path_1.joinpath('failu_nosaukumi.csv')
print(full_path)

我得到了实际结果（文件的完整路径和文件名），但是当我尝试读取该文件时：

faili = pd.read_csv(full_path, header=None, index_col=0).reset_index()

我收到错误：

Traceback (most recent call last):
  File "C:\Users\wotesi\AppData\Local\Temp\atom_script_tempfiles\d35090b0-aa8b-11ea-bb80-793ba6a5bb7c", line 19, in <module>
    faili = pd.read_csv(full_path, header=None, index_col=0).reset_index()

FileNotFoundError: [Errno 2] File C:\Users\wotesi\Documents\Cloud\Documents\Python\Programmas\panda\failu_nosaukumi.csv does not exist: 'C:\Users\wotesi\Documents\Cloud\Documents\Python\Programmas\panda\failu_nosaukumi.csv'

此外 - 当我运行使用 Anaconda/Spyder 相同的代码（没有完整路径，只是所有文件都在同一目录中）时，我没有得到任何错误。此错误在 Atom 中生成。如何修改代码使其在 Atom 中也能运行ning？此外，当我将该代码编译为 exe 模块并尝试从其他 Windows 机器运行时，它也会给出相同的错误消息 - 找不到文件。任何解决方案都适合我。谢谢！

您可以尝试这样的操作：

from pathlib import Path
path_1 = Path(r'C:\Users\wotesi\Documents\Cloud\Documents\Python\Programmas\panda')
faili = pd.read_csv(path_1.joinpath('failu_nosaukumi.csv'), header=None, index_col=0).reset_index()
