Re: [QUESTION] mxnet/Tuple vs nnvm/Tuple

[Lin Yuan]

Jun,

Thanks! I was also leaning towards your suggestion.
I have updated nnvm::Tuple to mxnet::Tuple for a few remaining places in

Best,

Lin

Re: Changes to MPI-operator

[Roshani Nagmote]

Sounds good. We(Pinar, Vandana and me) are currently prototyping and we are
planning to start a discussion on dev list once we have some logical
conclusion.
We will share more details soon and seek feedback from the community.

Thanks,
Roshani
