As you can see from below pictures, one model went wrong. From the Job view, it shows this job failed, and in the saved models, this "half-generated" model sticks here. I can't even find check box on the left. How could I remove it? this model causes an error when looping the saved models with python script.
I managed to delete this model. First check the box on the upper left corner to tick on all the model versions, then un-tick all the normal versions, and delete.
This looks like a small defect, the developer may need to amend this.
Small addition to your solution: you can type "running" in the filter on the saved model page, then click on a checkbox on the left of the "actions" button to select all of the corrupted versions. Then click Actions -> Delete
A second solution could be by creating a python notebook and running this snippet (change SAVED_MODEL_ID):
SAVED_MODEL_ID = '0tqFKYBZ'
pk = dataiku.Project().project_key
versions_to_delete = [v['versionId'] for v in m.list_versions() if v['snippet']['trainInfo']['state'] != 'DONE']
