[GitHub] [incubator-mxnet] yuxihu opened a new pull request #15591: Export symbols for checking cuda/cudnn versions

yuxihu opened a new pull request #15591: Export symbols for checking cuda/cudnn versions
URL: https://github.com/apache/incubator-mxnet/pull/15591
 
 
   Fixes #15578 
   
   Two functions (CudaLibChecks and CuDNNLibChecks) were added in #15551 to fix #15548. These two functions need to be exported in our pip package such that downstream projects consuming mxnet library will not encounter [undefined symbol error](https://github.com/horovod/horovod/issues/1217) as shown below:
   
   ```
   OSError: /home/ubuntu/anaconda3/envs/mxnet_p36/lib/python3.6/site-packages/horovod/mxnet/mpi_lib.cpython-36m-x86_64-linux-gnu.so: undefined symbol: _ZN5mxnet7Context13CudaLibChecksEv
   ```
