chrishkchris commented on issue #624: SINGA-487 Include NCCL and MPICH in conda build URL: https://github.com/apache/singa/pull/624#issuecomment-598231433 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.
