Alvinnyk opened a new pull request #717:
URL: https://github.com/apache/singa/pull/717


   Implemented vgg19 model from onnx model zoo.
   onnx model reference: https://github.com/onnx/models/tree/master/vision/classification/vgg
   
   Model conversion is done using `sonnx.prepare`
   
   - **Image preprocessing**
   Images are loaded in to a range of [0, 1] and then normalised using mean = [0.485, 0.456,
0.406] and std = [0.229, 0.224, 0.225] as per model specification.
   
   - **Postprocessing**
   Output is the softmax probability scores for each class and sorting them to report the
top 5 most probable classes.
