MLSL compiling error

[Rpona]

I git clone the latest version of intel caffe today.

When I make with "USE_MLSL=1", it will show make error as below:

make: *** [.build_release/src/caffe/solvers/nesterov_solver.o] Error 1

distrib_ = MLSL::Environment::GetEnv().CreateDistributionWithColors(dataColor, modelColor);

If I use default setting, it can be compiled well.
#USE_MLSL: 1
However, I found multi-node training are not synchronized.

Please make sure you don't have MLSL_ROOT env that points to an old version of MLSL. Suggest you clear MLSL_ROOT and the latest Caffe would download MLSL binary package automatically.

Thanks for your reply.
I used "rpm -e intel-mlsl-devel-64-2017.1-014.x86_64" to remove the order version of mlsl.
Then , I reboot the server and I didn't export "MLSL_ROOT".
I still got the same error message.

Could you please double check if there is MLSL_ROOT in your environment?

Hi, I fixed the issue. Thank you a lot :)

I found my intel caffe will download the order version "l_mlsl_p_2017.0.014 " of mlsl.
And there isn't "CreateDistributionWithColors" function in the header file "mlsl.hpp" of this version.
I install the latest version of mlsl from https://github.com/01org/MLSL/releases.
And followed these commands.
$ rpm --import PUBLIC_KEY.PUB
$ rpm -i intel-mlsl-devel-64-2017.1-016.x86_64.rpm
$source /opt/intel/mlsl_2017.1.016/intel64/bin/mlslvars.sh
then compile again.
