运行setup.py出现Error compiling objects for extension

[xhhlll]

作者您好！
我运行python setup.py develop时候出现,运行环境cuda11.0 python3.6 pytorch1.7.1 .请问怎么解决呢？
running develop
running egg_info
creating focalloss.egg-info
writing focalloss.egg-info/PKG-INFO
writing dependency_links to focalloss.egg-info/dependency_links.txt
writing top-level names to focalloss.egg-info/top_level.txt
writing manifest file 'focalloss.egg-info/SOURCES.txt'

@xhhlll 我在rtx2xxx, gtx1xxx上测试过是可以的；你的显卡是什么型号，下面的连接可以参考一下:smile:
安装时要保证cuda的版本与pytorch中对应的cuda版本一致
