Hi, potentially very silly and simple question, but I'm trying to run the cleanup_service.py in my services queue. However, it is not deleting any task but printing this line instead: WARNING:root:Could not delete Task ID=742e93cdfeac4f1c9395f0254fc443320, 'Task' object has no attribute 'delete' . I am kind of confused as to where to search. I tried numerous things - adding CLEARML_API_ACCESS_KEY and CLEARML_API_SECRET_KEY , but it doesn't change anything. It also doesn't seem to be a connection issue, since it can originally find the task IDs, so a connection of some sorts is going on. However, when deleting it fails with this strange error message. I tried searching github + so + this workspace but I cannot find an answer. Does anyone have a clue?
