ssd

I follow the instruction of example/ssd and run python demo.py from example/ssd directory and got an error below. My platform is firefly 3399. Is there a reason which ssd example is not working?

I have tested SSD from Incubator-mxnet head and it runs OK.
Do you have a plan to update mxnet to incubator-mxnet?
With this update, SSD maybe work OK.

Thanks
