“CSV file does not exist” - Pandas Dataframe

问题

I am currently learning Pandas for data analysis and having some issues reading a csv file in Atom editor.

When I am running the following code:

import pandas as pd 

df = pd.read_csv("FBI-CRIME11.csv")

print(df.head())

I get an error message, which ends with

OSError: File b'FBI-CRIME11.csv' does not exist

Here is the directory to the file: /Users/alekseinabatov/Documents/Python/"FBI-CRIME11.csv".

When i try to run it this way:

df = pd.read_csv(Users/alekseinabatov/Documents/Python/"FBI-CRIME11.csv")

I get another error:

NameError: name 'Users' is not defined

I have also put this directory into the "Project Home" field in the editor settings, though I am not quite sure if it makes any difference.

I bet there is an easy way to get it to work. I would really appreciate your help!

回答1:

Have you tried?

df = pd.read_csv("Users/alekseinabatov/Documents/Python/FBI-CRIME11.csv")

or maybe

df = pd.read_csv('Users/alekseinabatov/Documents/Python/"FBI-CRIME11.csv"')

(If the file name has quotes)

回答2:

Just referring to the filename like

df = pd.read_csv("FBI-CRIME11.csv")

generally only works if the file is in the same directory as the script.

If you are using windows, make sure you specify the path to the file as follows:

PATH = "C:\\Users\\path\\to\\file.csv"

回答3:

Had an issue with the path, it turns out that you need to specify the first '/' to get it to work! I am using VSCode/Python on macOS

回答4:

I also experienced the same problem I solved as follows:

dataset = pd.read_csv('C:\\Users\\path\\to\\file.csv')

回答5:

You are missing '/' before Users. I assume that you are using a MAC guessing from the file path names. You root directory is '/'.

回答6:

Being on jupyter notebook it works for me including the relative path only. For example:

df = pd.read_csv ('file.csv')

But, for example, in vscode I have to put the complete path:

df = pd.read_csv ('/home/code/file.csv')

回答7:

Just change the CSV file name. Once I changed it for me, it worked fine. Previously I gave data.csv then I changed it to CNC_1.csv.

回答8:

I had the same issue, but it was happening because my file was called "geo_data.csv.csv" - new laptop wasn't showing file extensions, so the name issue was invisible in Windows Explorer. Very silly, I know, but if this solution doesn't work for you, try that :-)

回答9:

Make sure your source file is saved in .csv format. I tried all the steps of adding the full path to the file, including and deleting the header=0, adding skiprows=0 but nothing works as I saved the excel file(data file) in workbook format and not in CSV format. so keep in mind to first check your file extension.

Adnane's answer helped me.

Here's my full code on mac, hope this helps someone. All my csv files are saved in /Users/lionelyu/Documents/Python/Python Projects/

import numpy as np
import pandas as pd
import matplotlib.pyplot as plt
plt.style.use('ggplot')

path = '/Users/lionelyu/Documents/Python/Python Projects/'

aapl = pd.read_csv(path + 'AAPL_CLOSE.csv',index_col='Date',parse_dates=True)
cisco = pd.read_csv(path + 'CISCO_CLOSE.csv',index_col='Date',parse_dates=True)
ibm = pd.read_csv(path + 'IBM_CLOSE.csv',index_col='Date',parse_dates=True)
amzn = pd.read_csv(path + 'AMZN_CLOSE.csv',index_col='Date',parse_dates=True)

回答11:

Run "pwd" command first in cli to find out what is your current project's direction and then add the name of the file to your path!

回答12:

Try this

import os 
cd = os.getcwd()
dataset_train = pd.read_csv(cd+"/Google_Stock_Price_Train.csv")

回答13:

What worked for me:

import csv
import pandas as pd
import os

base =os.path.normpath(r"path")



with open(base, 'r') as csvfile:
    readCSV = csv.reader(csvfile, delimiter='|')
    data=[]
    for row in readCSV:
        data.append(row)
    df = pd.DataFrame(data[1:],columns=data[0][0:15])
    print(df)


This reads in the file , delimit by |, and appends to list which is converted to a pandas df (taking 15 columns)

回答14:

In my case I just removed .csv from the end. I am using ubuntu.

pd.read_csv("/home/mypc/Documents/pcap/s2csv")

回答15:

If you get this type of Error

Then fix the path of the directory

回答16:

What works for me is

dataset = pd.read_csv('FBI_CRIME11.csv')

Highlight it and press enter. It also depends on the IDE you are using. I am using Anaconda Spyder or Jupiter.

回答17:

I am using a Mac. I had the same problem wherein .csv file was in the same folder where the python script was placed, however, Spyder still was unable to locate the file. I changed the file name from capital letters to all small letters and it worked.
