Error with install apex

I get this error installing with“python setup.py install --user --cuda_ext --cpp_ext”. Please advise! Thank you!

The report uses setup.py with --cuda_ext and --cpp_ext and reaches csrc/scale_check_overflow.cpp, but the compiler output is truncated. Start by reproducing the command and capturing the complete build error, then inspect the reported source and installation configuration. Done means the extension builds and the Apex install completes successfully.
