I have to open an excel file, and I do in this way:
xl_file = pd.ExcelFile('D:\mypath\myFile.xls')
On PyCharm(Python 2.7.8) it works perfectly, but on Jupyter(Python 3), I've always this error:
FileNotFoundError: [Errno 2] No such file or directory
What could be the reason?
This might happen if you call jupyter notebook at a place other than your root directory. In this case, jupyter might not have access to the file.
Try going to D: and calling jupyter notebook and then retrying this. Another option is to get the path of your notebook using:
os.path.abspath("__file__")
and then setting a relative path to the dataset.
Edit:
Let's say you want to set a path one level above the directory that contains the notebook. Then you would do:
foo = os.path.dirname(os.path.abspath("__file__"))
relative_path = os.path.join(foo, '..')
After having changed the Jupyter start folder as suggested in this post how to change jupyter start folder? , if the files are in this folder, to load them it isnt necessary to write the path. This is enough:
xl_file = pd.ExcelFile('myFile.xls')

I am trying to use Pillow Library in Python. I am writing basic code to open up a picture that I have saved.
But every time I run the code, it says
"can't open file 'C:\Users\saadn\PycharmProjects\Giraffe\main.py':
[Errno 2] No such file or directory".
The path for where the picture is saved is "C:\Users\saadn\PycharmProjects\Giraffe\DirectoryAssign1"
Now I know that in the error it says "Girrafe\main.py". but I don't have a python file named main at all. Someone guide me.
the code I wrote was
from PIL import Image
img = Image.open("dany.jpg")
img.show()
Here is a screenshot for better understanding.
Actually I think there are 2 issues, and not 1.
Error 1 - Wrong File is being tried to run :
In the picture you attached there is an error which means it cannot open main.py (No such file) . You entered a wrong file name, your file name is OpenAndShow.py
How to fix?
Be sure to open the terminal or command prompt and be sure you are in the following directory C:\Users\saadn\PycharmProjects\Giraffe\ and enter the following command as you are a Windows OS User:
py OpenAndShow.py
Fun fact: Of course Python won't search in the whole PC or directory (including folders which are in the directory) , so that's why you need to mention it is in a folder in the Giraffe folder!
Error 2 - Wrong location for the picture
If you had fixed error 1, you will get another error, that dany.jpg is not such file, why ? Because it is in another folder inside the folder your code is located, you can use dany.jpg when they are in the same folder, not in another folder in the same folder, in this case, it is in DirectoryAssign1 which is in Girrafe folder.
How to fix?
To fix it, change the path:
From : The current Path:
dany.jpg
To : The following path below:
DirectoryAssign1\dany.jpg
You are running the wrong file. In PyCharm, afaik you can right click on the file and run. Your PyCharm is now trying to run the file main.py.
Otherwise, you can use the terminal:
python OpenAndShow.py
Let's say I have the python file ~/file_to_run.py that I want to run from jupyter notebook (~/notebooks/my_notebook.ipynb) using the magic command %run. The problem is that file_to_run.py uses a relative path for example:
open('data/file.csv') # full path ~/data/file.csv
When I run ~/file_to_run.py from ~/notebooks/my_notebook.ipynb with:
%run ../file_to_run.py
I get the following error:
FileNotFoundError: [Errno 2] No such file or directory: 'data/file.csv'
Is the any fix without modifying the python file? Thank you!
Changing the working directory could be a solution:
import os
os.chdir('../') # Change the working directory
%run file_to_run.py # Call the script from new working directory
I am trying to open a .dat file by Pickle. Although the file is at the same folder as my .py file, when I run I get a FileNotFoundError.
(FYI: I am using VScode to run the file, however, it runs perfectly fine when I use Terminal)
here is my code
import pickle
websites_list = pickle.load(open("websites.dat","rb"))
print(websites_list)
This is the .py path:
/Users/lequangdang/Documents/WSC/WSC_2.0/changewebsiteGUI.py
here is the .dat path: /Users/lequangdang/Documents/WSC/WSC_2.0/websites.dat
Here is the error:
FileNotFoundError: [Errno 2] No such file or directory: 'websites.dat'
The relative path is base on work directory when using vscode, but is base on py file itself when using terminal.
For example the directory structure seems like:
WSC---WSC2.0---changewebsiteGUI.py
when you open WSC in vscode, pickle.load(open("websites.dat","rb")) will call the path WSC/websites.dat and that's why you have FileNotFoundError
one way to solve this is to set the vscode launch.json, add this line:
"cwd": "${workspaceRoot}/WSC2.0"
the other way is to use some function to get the abs path of pyfile itself:
os.path.dirname(os.path.abspath(__file__))
I am trying to scrape tables from pdf with read_pdf in python. I am using read_pdf but it doesn't do the job. Also, to mention, I do this in MAC with Jupiter notebook.
This is what I do:
from tabula import read_pdf
file = read_pdf(r'C:\Users\myname\Rprojects\Reports_scraping\data_scraped\icnarc_29052020\icnarc_200529.pdf')
I get this error:
FileNotFoundError: [Errno 2] No such file or directory: 'C:\\Users\\myname\\Rprojects\\Reports_scraping\\data_scraped\\icnarc_29052020\\icnarc_200529.pdf'
How I can solve this issue?
just to check that the file exist, do you get True when running this:
import os
file_path = r'C:\Users\myname\Rprojects\Reports_scraping\data_scraped\icnarc_29052020\icnarc_200529.pdf'
print( os.path.isfile(file_path))
Edit file_path with wherever is the file(using Python 3).
And did you change "myname" in the path with your actual username... (just in case)
It is preferable to build your paths using os.path.join to make things compatible, on windows it will need to create a root "config.py" file, see
how to get the root folder on windows

having discussed with GaB, it seemed that he is using Jupyter notebook on Mac, which explains issues, I saw this link, but can't help more.
Jupyter - import pdf
os.path.join doc
There can be only one possibility, the file is not there, but you have already checked that I assume, if not, Once again check whether the spelling of file is correct. If this doesn't work, then do below trick
Execute the py code in same folder as file, and then use
from tabula import read_pdf
file = read_pdf(r'icnarc_200529.pdf')
Sometimes, this simple method does the trick.
I just try to create some new folders with Python's (3.7.3) os.makedirs() and os mkdir().
Apparently, it works fine because no error occurs (Win 10 Home). But as I try to find the created folder in the windows explorer it isn't there.
Trying to create it again with python I get an error:
'[WinError 183] Cannot create a file when that file already exists:'
Strange thing is, all this worked fine on my computer at work (Wind 10 too), and also on my android tablet.
I've already tried to use relative & absolute paths in makedirs / mkdir.
Ok, it's all about these few lines:
import os
# print(os.getcwd()) shows: C:\Users\Andrej\Desktop
# tried relative path..
os.makedirs('Level1/Level2/Level3')
# tried out some absolute paths like...
os.makedirs('C:/Users/Andrej/Desktop/Level1/Level2/Level3')
os.makedirs('C:\\Users\\Andrej\\Desktop\\Level1\\Level2\\Level3')
UPDATE: It works perfectly when I write makedirs command directly in the Windows powershell. The issue above only occurs when I write this code in Visual Code Studio and then start the file from the powershell by typing in: python makedirs.py...
I just had the same thing happen to me, except I was creating a folder in the AppData/Roaming directory and was using the version of Python from the Microsoft Store.
Apparently, files and directories created in AppData using that version of Python, will instead be created in:
%LocalAppData%\Packages\PythonSoftwareFoundation.Python.3.8_qbz5n2kfra8p0\LocalCache
I found what causes this problem finally!
All of the created test folders have been moved to a folder named VTROOT. This folder is created by Comodo Internet Security I use...Its "Auto-Containment" moved all folders I set up by running the code from .py-file (only then) in the PowerShell.
Disabling the auto-containment of Comodo solves the problem..Oh my..
Thank you anyways!
the "if" part will check if the file exists already and consequentially solve the ERROR: '[WinError 183] Cannot create a file when that file already exists:'
the "import sys" part will fix the issue with windows where the folder is created but not visible by the user (even with show hidden files turned on)
import sys
import os
path = 'your path'
def make_dir():
if not os.path.exists(Path):
os.makedirs(Path)
or
import sys
import os
path = 'your path'
def make_dir():
mode = 0o666 #read and write for all users and groups
# form more permission codes search for: *chmod number codes*
if not os.path.exists(Path):
os.mkdir(Path, mode)
Try adding the below import statement:
import sys
This should work.
