Test SINGA ONNX Converter

[moazreyad]

We need to try the ONNX converter with AlexNet

The ONNX converter is here:

https://github.com/moazreyad/incubator-singa/tree/onnx/tool/onnx

Steps:

1. Get the AlexNet from Pytorch:

http://pytorch.org/docs/master/onnx.html

from torch.autograd import Variable
import torch.onnx
import torchvision

dummy_input = Variable(torch.randn(10, 3, 224, 224)).cuda()
model = torchvision.models.alexnet(pretrained=True).cuda()
torch.onnx.export(model, dummy_input, "alexnet.proto", verbose=True)

2. Convert to SINGA using the ONNX converter :

onnx_to_singa file.proto

3. Test the converted model in SINGA and report the issues to be fixed.
