Unable to define path in Chapter 5 JupyterNotebook

Part 1 (2020)

Hello there,
So i just received an error message from the third code block from the Chapter 5 in Jupyter, the code up to where i am is just:

!pip install -Uqq fastbook
import fastbook
fastbook.setup_book()

from fastbook import *

from fastai.vision.all import *
path = untar_data(URLs.PETS)

And i get this error traceback:

"

224 except OSError:
225 # Cannot rely on checking for EEXIST, since the operating system

FileExistsError: [Errno 17] File exists: ‘/storage/data/oxford-iiit-pet’

I tried to wrap my head around what’s written, but i could not. Could anyone help me with this?

Hi! I think it has to do with the folder already being present in your download-to path. If you’re using Linux you should be able to do rm -rf /storage/data/oxford-iiit-pet or on Windows you should be able to navigate to this path and remove it. Maybe try again after doing this?

Oh, thank you very much! Little to no experience in linux and the Paperspace got me confused.
It works now

Is there a tutorial on how to do this??? I ran into this problem myself and don’t know where to find the file to remove.

Ahh got it nevermind…

ran the code you provided

rm -rf /storage/data/oxford-iiit-pet

before re-running the

from fastai.vision.all import *
path = untar_data(URLs.PETS)

and that worked!
