pandas.read_csv file not found despite correct pat

问题:

I'm trying to load a .csv file using the pd.read_csv() function when I get an error despite the file path being correct and using raw strings.

import pandas as pd
df = pd.read_csv('‪C:\\Users\\user\\Desktop\\datafile.csv')
df = pd.read_csv(r'‪C:\Users\user\Desktop\datafile.csv')
df = pd.read_csv('C:/Users/user/Desktop/datafile.csv')

all gives the error below:

FileNotFoundError: File b'\xe2\x80\xaaC:/Users/user/Desktop/tutorial.csv' (or the relevant path) does not exist.

Only when i copy the file into the working directory will it load correct.

Is anyone aware of what might be causing the error?

I had previously loaded other datasets with full filepaths without any problems and I'm currently only encountering issues since I've re-installed my python (via Anaconda package installer).

Edit:
I've found the issue that was causing the problem.
When I was copying the filepath over from the file properties window, I unwittingly copied another character that seems invisible.
Assigning that copied string also gives an unicode error.

Deleting that invisible character made any of above code work.

回答1:

Try this and see if it works. This is independent of the path you provide.

pd.read_csv(r'C:\Users\aiLab\Desktop\example.csv')

Here r is a special character and means carriage return. So prefix it to your string literal.

$10 says your file path is correct with respect to the location of the .py file, but incorrect with respect to the location from which you call python

For example, let's say script.py is located in ~/script/, and file.csv is located in ~/. Let's say script.py contains

import pandas
df = pandas.read_csv('../file.csv') # correct path from ~/script/ where script.py resides

If from ~/ you run python script/script.py, you will get the FileNotFound error. However, if from ~/script/ you run python script.py, it will work.

I know following is a silly mistake but it could be the problem with your file.

I've renamed the file manually from adfa123 to abc.csv. The extension of the file was hidden, after renaming, Actual File name became abc.csv.csv. I've then removed the extra .csv from the name and everything was fine.

Hope it could help anyone else.

import pandas as pd

path1 = 'C:\\Users\\Dell\\Desktop\\Data\\Train_SU63ISt.csv'
path2 = 'C:\\Users\\Dell\\Desktop\\Data\\Test_0qrQsBZ.csv'

df1 = pd.read_csv(path1)
df2 = pd.read_csv(path2)

print(df1)
print(df2)

If you are using windows machine. Try checking the file extension. There is a high possibility of file being saved as fileName.csv.txt instead of fileName.csv You can check this by selecting File name extension checkbox under folder options (Please find screenshot)

below code worked for me: df = pd.read_csv(r"C:\Users\vj_sr\Desktop\VJS\PyLearn\DataFiles\weather_data.csv");

if fileName.csv.txt Rename/correct it as fileName.csv

Hope it works, Good Luck

Try using os.path.join to create the filepath:

import os
f_path = os.path.join(*['C:', 'Users', 'user', 'Desktop', 'datafile.csv'])
df = pd.read_csv(f_path)

回答7:

I was trying to read the csv file from the folder that was in my 'c:\'drive but, it raises the error of escape,type error, unicode......as such but this code works just take an variable then add r to read it.

rank = pd.read_csv (r'C:\Users\DELL\Desktop\datasets\iris.csv') 
df=pd.DataFrame(rank)

回答8:

There is an another problem on how to delete the characters that seem invisible.

My solution is copying the filepath from the file windows instead of the property windows.

That is no problem except that you should fulfill the filepath.

回答9:

Experienced the same issue. Path was correct. Changing the file name seems to solve the problem.

Old file name: Season 2017/2018 Premier League.csv New file name: test.csv

Possibly the whitespaces or "/"
