title: TensorflowLite iOS example issue
body: <p>I have downloaded the tensorflowlite Posenet example for iOS from the official GitHub account</p>
  <p><a href="https://github.com/tensorflow/examples/tree/master/lite/examples/posenet/ios" rel="nofollow noreferrer">https://github.com/tensorflow/examples/tree/master/lite/examples/posenet/ios</a></p>
  <p>I am able to run the example on the device but it gives the following error</p>
  <p><strong>2021-05-18 00:57:50.385071+0530 PoseNet[8112:3939417] Resizing Error: source image ratio and destination image ratio is different

  2021-05-18 00:57:50.385797+0530 PoseNet[8112:3939417] Cannot get inference result.</strong></p>
  <p>Has anyone faced this issues and how do we solve it?</p>
