title: Tensorflow - Inference time evaluation
body: <p>I'm evaluating different image classification models using Tensorflow, and specifically inference time using different devices.
  I was wondering if I have to use pretrained models or not.
  I'm using a script generating 1000 random input images feeding them 1 by 1 to the network, and calculating mean inference time.</p>
  
  <p>Thank you !</p>
