Answer

Hi,

To make a better debug, could you please let me know what is the script of the aws cli you called or provide the return response with empty value? 
Also, please let me know the arn of you model.

Thanks,

Answer

As discussed further on [this page](https://docs.aws.amazon.com/rekognition/latest/customlabels-dg/detecting-custom-labels.html), Rekognition applies **confidence thresholding** on returned labels - using assumed thresholds by default unless you specifically configure something different. Probably for this test image your model is not confidently detecting any labels, so all detections are being thresholded out.

You can try specifying [MinConfidence](https://docs.aws.amazon.com/rekognition/latest/APIReference/API_DetectCustomLabels.html#rekognition-DetectCustomLabels-request-MinConfidence) in your `DetectCustomLabels` API call to `0` to return all labels regardless of detected confidence?
