   1. The script for travis building is singa/tool/travis/build.sh: 
   line 32 is conda build tool/conda/singa --python 3.6
   If I understand correctly, both CPU build (by Travis) and GPU build are depended on the
same folder tool/conda/singa for the conda config (I saw lots of conda libraries sharing between
the CPU and GPU versions in this config file)
   Therefore, the reason I create the new folder is to NOT include the GPU related library
(cudnn, nccl, mpich) , and this folder is used only by the CPU Travis build. The original
folder (tool/conda/singa)
    is retained for singa-gpu build.
   
   In this case, I modified the line 32 of singa/tool/travis/build.sh to conda build tool/conda/singa/travis
--python 3.6
   
   2. Thanks a lot for this method, I will delete the new folder added above and try your
method instead. I suppose conda/cpu and conda/gpu are the additional config added on top of
the config file in conda/singa, to distinguish the CPU and GPU versions of singa.
