[GitHub] [singa] chrishkchris opened a new pull request #759: Update CXX compiler to 7.5.0 in Conda version of SINGA

chrishkchris opened a new pull request #759:
URL: https://github.com/apache/singa/pull/759


   For conda version of SINGA:
   
   This is to fix the issue in https://github.com/apache/singa/pull/758
   
   It requires to use explicit type in cuda kernal, which cannot use "auto" instead
   
   Upgrade the CXX compiler to 7.5.0 can solve the problem (note that the docker version of singa currently using 7.5.0 also)

   can we change the 'auto' to the specific type to fix this issue?
   if we upgrade the gcc, we the compiled .so file may require higher versions of libstc++, which may not be available in some systems.
