Task Scheduler error: 'Cannot create a file when that file already exists'

[LAgeoNative]

Description

Scheduling a task to execute now. However, after running for 2 seconds, it stops and produces an error that says 'Cannot create a file when that file already exists'

Reproduce

1. This is my following code where it seems to produce the error message:

   currentYear = datetime.now().year def month_format(): currentMonth = datetime.now().month currentMonth = str(currentMonth) if len(currentMonth) < 2: currentMonth = "0" + currentMonth return currentMonth

   currentMonth = month_format() folder_date = str(currentYear) + str(currentMonth) path_date = './' + folder_date + '/' os.mkdir(path_date)

   

Expected behavior

Scheduler creates the folder without giving me the error messages mentioned from the description

At the time you ran this script, did a directory called 202306 already exist under your JupyterLab root? If so, then the error is genuine.

If you want to run a job repeatedly with this command in it, consider adding a check for the directory before you create it.

Hello,

Thank you for the response. I actually deleted the directory locally on my machine and it still thinks it exists. Is this run on somewhere else instead of it being locally?

I searched the web for WinError 183 and found this StackOverflow thread with a lot of examples. Deleting a file in Windows may not cause it to be removed immediately from the file system if some other process has a handle on it. (This happens with other Unix-like OSes as well, including Linux and macOS.)

You might be able to get around this in your script by checking whether the target directory already exists, and if it does, ignore the FileExistsException and continue execution.
