    hi guys, can i join this, did statistics/machine learning at grad school and doing all sorts of coding at work (C++/python/R/javascript/and some crazy internal functional language) but never got a chance to do both at the same time. I will do my best to contribute.
    used the xgboost tool and it's awesome

    cool:)
    to list the features we are not yet able to add to dmlc-core and we are looking for contributions
    please feel free to open new issues if you have something in mind

    Is there plan to add support for vowpal wabbit data format? I found it really convenient when dealing with complex datasets.

    I don't have that much machines ,do you think it is good to use docker to expand the number of machines?

    I'm trying to build minerva and I'm getting "fatal error: config.h: No such file or directory" from gflags
    Bob Poekert
    @bobpoekert
    problem seems to be solved by commenting out the gflags dependency in the third_party CMakeLists.txt
    does minerva really only work with cuDNNv2? isn't that quite old now?
    Bob Poekert
    @bobpoekert
    is minerva still maintained? has everything been rolled into mxnet at this point?
    I'm not doing neural nets, I'm just looking for a fast GPU tensor library I can use from python
    Bob Poekert
    @bobpoekert
    should I be using minpy?
    looks like most of it i
    isn't implemented yet, so probably not

    Hi all, does anyone know if it is possible to have the nodes in a cluster train on different subsets of the data with XGBoost? Or does every node need to load in all of the data?

    Hi all, I have done some experimental work on Mesos integration on dmlc-core. I do not know whether or not do the dmlc guys like this.

    Hey folks! Is dmlc-core a header only library?
    Tianqi Chen
    @tqchen
    it is we need compiled libs for the filesystems
    but many of the project depend on it only uses logging, json and serialization
    which are header only

    I train my dataset on ubuntu system with python code.
    I test my model on MAC with c++ code.when I load the xxx.json,some errors happened:

    WorkSpace/mxnet/dmlc-core/include/dmlc/./json.h:842: JSONReader: Unknown field attrs, candidates are:

    @tqchen how to assign nnvm::Tuple<dmlc::optional<float>> a ? When I use a = nnvm::Tuple<float>{1.f, 2.f}; it seems wrong.

    @lilongyue
    hello anybody here?
    i see some implementation of std lib function like : 'any , ' in the dmlc-core source code
    since 'any' is in the standard lib from c++17 ,
    so is it true that the whole dmlc-core is designed for c++11 ?
    lilongyue
    @lilongyue
    is this for the gpu programming cuda which only support c++11 ?
    can any one give some info about why the core is designed not using latest c++17 features?
    @tqchen @mli
    i checked that ' CUDA 10.0 supports C++14 but not C++17.'

    hey there, I'm trying to do multi-node/multi-GPU distributed training on AWS Sagemaker using one of GluonCV models. And i'd like to use DMLC tracker to run jobs using MPI protocol. Sagemaker MXNet container image comes with already pre-installed openmpi (specifically, "mpirun.real (OpenRTE) 4.0.1"). When i'm trying to mpi.submit I'm getting this exception: https://github.com/dmlc/dmlc-core/blob/dc0156a73a846751851fcf130729ade6360a37b1/tracker/dmlc_tracker/mpi.py#L35. Can someone confirm that mpirun.real is supported by DMLC? If yes, any examples on how to run the task on the cluster?

    Does anybody have an example of XGBoost in recommendation systems problem-solving (predict whether a given user would be interrested in an item/product)
