[Django]-OSError – Errno 13 Permission denied

This may also happen if you have a slash before the folder name:

path = '/folder1/folder2'

OSError: [Errno 13] Permission denied: '/folder1'

comes up with an error but this one works fine:

path = 'folder1/folder2'

Probably you are facing problem when a download request is made by the maybe_download function call in base.py file.

There is a conflict in the permissions of the temporary files and I myself couldn’t work out a way to change the permissions, but was able to work around the problem.

Do the following…

• Download the four .gz files of the MNIST data set from the link ( http://yann.lecun.com/exdb/mnist/ )
• Then make a folder names MNIST_data (or your choice in your working directory/ site packages folder in the tensorflow\examples folder).
• Directly copy paste the files into the folder.
• Copy the address of the folder (it probably will be
  ( C:\Python\Python35\Lib\site-packages\tensorflow\examples\tutorials\mnist\MNIST_data ))
• Change the “\” to “/” as “\” is used for escape characters, to access the folder locations.
• Lastly, if you are following the tutorials, your call function would be ( mnist = input_data.read_data_sets(“MNIST_data/”, one_hot=True) ) ;
  change the “MNIST_data/” parameter to your folder location. As in my case would be ( mnist = input_data.read_data_sets(“C:/Python/Python35/Lib/site-packages/tensorflow/examples/tutorials/mnist/MNIST_data”, one_hot=True) )

Then it’s all done.
Hope it works for you.

Another option is to ensure the file is not open anywhere else on your machine.

supplementing @falsetru’s answer : run id in the terminal to get your user_id and group_id

Go the directory/partition where you are facing the challenge.
Open terminal, type id then press enter.
This will show you your user_id and group_id

then type

chown -R user-id:group-id .

Replace user-id and group-id

. at the end indicates current partition / repository

// chown -R 1001:1001 . (that was my case)

Simply try:

sudo cp /source /destination

Just close the file in case it is opened in the background. The error disappears by itself

The solution that worked out for me here when I was using python 3 os package for performing operations on a directory where I didn’t have sufficient permissions and access to got resolved by running the python file with sudo (root) i.e.:

sudo python python_file_name.py

Any other utility that you might also plan on using to chmod or chown that directory would also only work when you run it with sudo.

# file_name.py
base_path = "./parent_dir/child_dir/"
user = os.stat(base_path).st_uid # for getting details of the current user owner of the dir
group = os.stat(base_path).st_gid # for getting details of the current group owner of the dir

print("Present owner and group of the specified path")
print("Owner:", user)
print("Group:", group)
os.chown(base_path, user, group) # change directory permissions

print("\nOwner id of the file:", os.stat(base_path).st_uid)
print("Group id of the file:", os.stat(base_path).st_gid)
os.mkdir(base_path+file_name,mode=0o666)

run the above file with sudo.

sudo python file_name.py

Hope this answer works out for you.
