title: How to download and use object detection datasets (e.g. coco or pascal)
body: <p>I am super new to the field of object detection.
  I was wondering if anyone can help me somehow on how I can download and use the object detection datasets such as coco or pascal. When I go to their website even after downloading the datasets i feel like i dont know what should i do with them...
  I know this question is stupid, but a hint to start can be super useful.
  Thanks</p>
