title: How to Re-train custom yolo weights?
body: <p>I have done a custom detection in YOLOv3 over 3 classes, but the detections were not accurate so I want to retrain my custom YOLO weights with more images, but
  when I run it with new images it immediately finished, what is it that I have done wrong?</p>
  <p>Here how I train it</p>
  <pre><code> !./darknet detector train data/obj.data cfg/yolov3_custom.cfg yolov3_custom_last.weights
  </code></pre>
  <p>The content of obj.data:</p>
  <pre><code>classes = 3
  train = data/train.txt
  valid = data/test.txt
  names = data/obj.names
  backup = /mydrive/yolov3/backup/
  </code></pre>
  <p>The content of yolov3_custom.cfg:</p>
  <pre><code># Training
