   > Thanks for the catch. Would you be able to either add a test that shows when this fails, or to give some minimal steps to reproduce (i.e. the build flags and build systems your using)? Ideally we'd like to make sure that we don't regress on this once it's fixed.
   
   Thanks for your reply.
   In my personal environment, I didn't get any error associated with the website issues. However, my fixed issues is the compiling error in enabling DEBUG.
   The related code is in the src/kvstore/kvstore_nccl.h lines 345, i.e., "assert(root == buf.ctx().dev_id);"
   the buf is an objection of BufferEntry, which contains an objection of NDArray, namely, merged.
   It is the merged implements the ctx() function calls, rather than the buf.
   The key configurations in my environment are described as follows.
   OS: Ubuntu-1604 x64
   GCC: 5.4.0
   CUDA: 9.0.176
   NCCL-2.1.15
   cuDNN: 7.2
