OSError: Initializing from file failed on csv in Pandas

So far pandas read through all my CSV files without any problem, however now there seems to be a problem..

When doing:

df = pd.read_csv(r'path to file', sep=';')

I get:

OSError Traceback (most recent call last) in () ----> 1 df = pd.read_csv(r'path Übersicht\Input\test\test.csv', sep=';')

OSError: Initializing from file failed

Other files in the same folder that are XLS files can be accessed without an issue.

When using the Python library like so:

import csv
file = csv.reader(open(r'pathtofile')) 

for row in file:
    print(row)
    break

df = pd.read_csv(file, sep=';')

the file is being loaded and the first line is printed. However I get:

ValueError: Invalid file path or buffer object type:

Probably because I can't use read_csv this way...

How to get the first pandas function to work? The csv does not contain any special characters except German ones. The filesize is 10MB.

Solution 1:

import pandas as pd
pd.read_csv("your_file.txt", engine='python')

Try this. It totally worked for me.

Solution 2:

I ran into a similar problem. It turned out the CSV I had downloaded had no permissions at all. The error message from pandas did not point this out, making it hard to debug.

Check that your file have read permissions

Solution 3:

I had the same issue, you should check your permissions.

After chmod 644 file.csv it worked well.
