gcc - 不受支持的 GNU 版本！不支持高于 7 的 gcc 版本

Question

我正在尝试使用 pip 安装 cupy 5.0.0。它依赖于 gcc-7。在我的系统中，默认 gcc 设置为版本 8。我还安装了 cuda-10.0。

我正在设置环境变量以使用 gcc-7 编译器。但是 nvcc 仍然使用默认的 gcc-8 并给出错误。

我不能使用 conda 环境。我也没有 sudo 权限。

试图

export CXX=/usr/bin/g++-7
export CC=/usr/bin/gcc-7
export LD=/usr/bin/g++-7

pip3 install cupy==5.0.0
