title: YOLOv3) compiles and run. But no predictions
body: <p>I'm using macOS Catalina.</p>
  
  <p>I'm just following the basic tutorial which are written in the <a href="https://pjreddie.com/darknet/yolo/" rel="nofollow noreferrer">Darknet page</a>.</p>
  
  <p>when I run the command</p>
  
  <pre><code>$make
  $./darknet detect cfg/yolov3.cfg yolov3.weights data/dog.jpg
  </code></pre>
  
  <p>then the Yolo is not predict after just showing the running time</p>
  
  <pre><code>Loading weights from yolov3.weights...Done!
  data/dog.jpg: Predicted in 19.215062 seconds.
  </code></pre>
  
  <p>Also, prediction.jpg is saved without any boundary box</p>
  
  <p>I tried also</p>
  
  <pre><code>$./darknet detect cfg/yolov3.cfg yolov3.weights data/dog.jpg -thresh 0
  </code></pre>
  
  <p>But it doesn't work.
  Can anyone help me please?</p>
