I'm trying to do a quick PoC on the AWS Rekognition custom labels feature. I'd like to try using it for object detection.
I've had a couple of attempts at setting it up using only tools in the AWS Console. I'm using images imported from the Rekognition bucket in S3, then I added bounding boxes using the tools in the Rekognition console.
All of my images are marked up with bounding boxes, no whole image labels have been used. I have 9 labels, all of which appear in at least 1 drawing.
I've ensured my images are less than 4096x4096 in size (which is mentioned on this AWS forums thread as a possible cause of this issue.
When I attempt to train my model I get the "The manifest file contains too many invalid data objects" error.
What could be wrong here? An error message complaining about the format of a file I didn't create manually, that I can't see or edit isn't exactly intuitive.
