Hi @malia05 ,

If all the tests passed successfully while building CoS, make sure you have set all the PATH's correctly. If you are using a Mac, then check DYLD_LIBRARY_PATH and for ubuntu check LD_LIBRARY_PATH.

If you just export the variables one time, those variables will be reset when you reboot your system. Please add these lines to your .bash_profile or a similar file.

export DYLD_LIBRARY_PATH=${CAFFE_ON_SPARK}/caffe-public/distribute/lib:${CAFFE_ON_SPARK}/caffe-distri/distribute/lib
export DYLD_LIBRARY_PATH=${DYLD_LIBRARY_PATH}:/usr/local/cuda/lib:/usr/local/mkl/lib/intel64/
export LD_LIBRARY_PATH=${DYLD_LIBRARY_PATH}

This will export the variables every time you log in to your user account.

Please let me know if it helped.

Thanks, Arun
