我如何看一台ubuntu 18.04 机器上安装得pytorch对应得 cuda 版本呢？
How can I see the corresponding cuda version of pytorch installed on an ubuntu 18.04 machine?

mim install "mmcv>=2.0.0rc1,<2.1.0" 时自动匹配的时cu102，是pytorch 1.10.0 安装的就是 cu102 的版本吗？
mim install "mmcv>=2.0.0rc1,<2.1.0" when automatically matched with cu102, is pytorch 1.10.0 installed is the version of cu102?

但是我nvcc -V 出来的是 cuda_11.1.TC455_06.29190527_0，在使用mmdeploy时会不会有影响。
But my nvcc -V comes out as cuda_11.1.TC455_06.29190527_0, will it have any effect when using mmdeploy.

mim 是如何匹配 mmcv 对应的 cuda 版本的?
