python - FileNotFoundError: [Errno 2] No such file or directory , adding 'r' prefix adds an extra slash which makes the directory don't exist

Question

I am using google colab, and this should be a simple problem but mine is so confusing. My program just couldn't detect directory. I have tried adding "r" prefix at the string, which doubled the slashes in the address- making the program unable to find where the folder is.

TRAIN_DIR = r'C:UsersAshOneDriveDesktopFYPrain'

and the error result :

FileNotFoundError: [Errno 2] No such file or directory: 'C:\Users\Ash\OneDrive\Desktop\FYP\train'

Why double slashes all of the sudden :(

I tried using "/" , double slashes, it all don't work.
