Known issues

Why do I get \r error when running my Python script?

If you encounter an error message like: /usr/bin/env python3/r: bad interpreter: No such file or directory while running a .py file, it might be because the file was edited on your local Windows computer before moving it to AI-LAB. Line endings often get converted when files are moved between Linux and Windows. This conversion is a frequent issue as Linux and Unix-like systems use \n for line breaks, whereas Windows uses \r\n (CRLF, Carriage Return + Line Feed).

Solution: In code editors such as VS Code or PyCharm, you can switch between LF (Linux endings) and CRLF (Windows endings) from the right-hand side of the status bar at the bottom of the window. Therefore, use LF endings if you wish to move a file to AI-LAB.

Why do I get Error generating job credential when running a job?

Sometimes there are challenges with Active Directory (AD) at Aalborg University where AD fails to translate UIDs to people's usernames. Consequently, Slurm may encounter authentication issues, preventing you from running a job, and you may notice the job hanging when you run sinfo.

Solution: Often, the problem resolves itself after some time (~20 minutes), and you will be able to run jobs again. You can also try running the id command to translate the username to UID, which usually gets cached and starts working after a while.
