Code compilation error

[PGDneedoffer]

when I run python setup.py develop, it appears

My system is Centos7, gcc7.4.0, cuda10.1, have you encountered such an error, how can I solve this compilation error?

我上面的编译报错后运行测试代码报错：ImportError: cannot import name 'corner_pool_ext' from 'mmdet.ops.corner_pool' (/home/deployer/RepPointsV2-master/mmdet/ops/corner_pool/init.py)

[cuihu1998]

the code can only be compiled by GCC 5.4.0, and this version is very hard to install.
