title: Error on running Super Resolution Model from ONNX
body: <p>Testing ONNX model for <a href="https://github.com/onnx/models/tree/master/vision/super_resolution/sub_pixel_cnn_2016" rel="nofollow noreferrer">super resolution model</a>, I have error running <a href="https://github.com/onnx/models/blob/master/vision/super_resolution/sub_pixel_cnn_2016/dependencies/Run_Super_Resolution_Model.ipynb" rel="nofollow noreferrer">this sample program</a>.</p>
  <p>My ONNX version is 1.5.0 with onnxruntime 1.4.0. <a href="https://pypi.org/project/onnxruntime/" rel="nofollow noreferrer">Onnxruntime was installed using pip</a>.
  Pytorch version is 1.6.0</p>
  <p>Error is at <code>ort_session = onnxruntime.InferenceSession('/home/itc/pytorch/sub_pixel_cnn_2016/model/super-resolution-10.onnx')</code></p>
  <p>The error is in loading onnx model.</p>
  <pre><code>Traceback (most recent call last):
