title: Map/graph not appearing when training on darknet?
body: <p>I am currently training on Darknet YOLO using AlexeyAB's version for linux on the master branch (<a href="https://github.com/AlexeyAB/darknet" rel="nofollow noreferrer">https://github.com/AlexeyAB/darknet</a>) and the map/graph does not appear in a second, separate window.</p>
  
  <p>My makefile is original except that I changed GPU = 1. 
  I configured my .cfg, .data, .names and weights files and I am able to successfully train on 2000 iterations, however, the map/graph does not appear when I begin training and as a result, I have to take screenshots of my terminal every now-and-then to make sure training is going well. </p>
  
  <p>Here is the command I use to train:</p>
  
  <pre><code>$ ./darknet detector train data/obj.data yolo-obj.cfg darknet53.conv.74
  </code></pre>
  
  <p>I have tried adding the <code>-map</code> flag to the end as so:</p>
  
  <pre><code>$ ./darknet detector train data/obj.data yolo-obj.cfg darknet53.conv.74 -map
  </code></pre>
  
  <p>but it still does not appear. Am I missing something in my command or in my config?</p>
  
  <p>Thank you in advance!</p>
