I am trying to create an Object Detection model with CreateML.

But no matter what I do, every time I press "Train" I get the message "Unexpected Error". But without any further information.

Here is the annotations.json data:

[{"image":"bild.jpg","annotations":[{"label":"sneakers","coordinates":{"y":875,"x":473,"width":236,"height":602}}]},{"image":"bild2.jpg","annotations":[{"label":"sneakers","coordinates":{"y":883,"x":440,"width":245,"height":605}}]},{"image":"bild3.jpg","annotations":[{"label":"sneakers","coordinates":{"y":608,"x":362,"width":222,"height":522}}]},{"image":"bild4.jpg","annotations":[{"label":"sneakers","coordinates":{"y":777,"x":411,"width":254,"height":687}}]}]

And here screenshots from CreateML:

Does anyone have any idea what I am doing wrong?

  • complete guess, but maybe it needs more than one image to do the validation split? you could try duplicating your image to see if that makes it work – Nate Lowry Jul 06 '21 at 20:20
  • I already had the same thought. I have also tried that. I even have downloaded an example project (images with annotation separated into test, train, valid). Nevertheless "unexpected error" comes again and again. – Felix Wpoint Jul 18 '21 at 20:21
  • Hmmm...I think there's a way to view error logs, but I don't know what that is. What hardware are you on? Does xcode and its tools need to be installed too? Sometimes there's just a random popup you need to accept. Also, what happens if you try a different directory? – Nate Lowry Jul 20 '21 at 01:54

I had GPU timeout and other issues. Just cancelling the error and clicking on Resume Training worked for me. The error might pop up for a few times, but after a while, the process will continue.
