   Thank you @olk for reporting the issue.
   
   I see your github repository does not include 8 commits of official master 
branch. Why so?
   
   Could this be due to compiling for too many cuda arches, causing your linker 
to fail due to too large binary size 
(https://github.com/apache/incubator-mxnet/issues/16852). In that case you need 
to set -DMXNET_CUDA_ARCH="7.0,7.5" or whatever arches you are interested in.
   There is an upstream issue about this problem 
(https://gitlab.kitware.com/cmake/cmake/issues/20275), though for MXNet side we 
can just include a patched `select_compute_arch.cmake`.
   
   In general, you should include the complete output in your issue 
description. Your current description is insufficient to diagnose the error. 
I'll try to reproduce locally and update about the result soon.
