cub has been moved to 3rdparty folder. Update your submodule and try again.

@reminisce Thank you! Can you tell me the detail?
I just git clone code yesterday. Why it is not work.
So I don't know which submodule need to update.

@Feywell

cd mxnet
git submodule update --init

You can also try the following command if that does not work.

cd mxnet/3rdparty
git submodule add https://github.com/dmlc/cub cub
