Subject [GitHub] [singa] chrishkchris opened a new pull request #759: Update CXX compiler to 7.5.0 in Conda version of SINGA
Date Thu, 02 Jul 2020 16:46:03 GMT

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)
