不支持更高版本的 gcc

Question

我刚刚设置了一个 Ubuntu。 我正在尝试改变暗网的 yolo。我遇到了这个错误。

/usr/local/cuda/include/crt/host_config.h:138:2: error: #error -- unsupported GNU version! gcc versions later than 8 are not supported!
  138 | #error -- unsupported GNU version! gcc versions later than 8 are not supported!

我也试过了

sudo apt install gcc-4.9 g++-4.9

我明白了

Package g++-4.9 is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

E: Package 'gcc-4.9' has no installation candidate
E: Package 'g++-4.9' has no installation candidate

下载最新版本似乎出现版本错误。 你知道如何降级gcc版本吗？

我解决了！

Python 版本控制是原因。

通过重新建立和重新安装包的路径解决了。
