title: Tensorflow empty model.ckpt
body: <p>I try to design my own model detector on tensorflow with objectdetector API.</p>
  
  <p>I run the <em>running pet</em> example, but it tells me this:</p>
  
  <blockquote>
    <p>To speed up the training process, it is recommended that users re-use the feature extractor parameters from a pre-existing object classification or detection checkpoint. train_config provides two fields to specify pre-existing checkpoints: fine_tune_checkpoint and from_detection_checkpoint. fine_tune_checkpoint should provide a path to the pre-existing checkpoint (ie:"/usr/home/username/checkpoint/model.ckpt-#####")</p>
  </blockquote>
  
  <p>Is it possible not to indicate the fine_tune_checkpoint and the model.ckcp, or to get an empty model?</p>
  
  <p>Edit: I just notice that the model.ckpt is used in object_detection algorithm. How can I do my own model.cfpt?</p>
