文章介绍了如何查看Torch和CUDA的版本，提供了从预编译包和源码两种方式安装mmcv的方法，并详细展示了环境验证过程。当遇到`frommmcvimportConfig`报错时，建议安装mmcv-full的低版本（小于2.0.0）来解决问题。

可以直接参考教程：
找到pip安装，选择自己的cuda和torch版本，复制指令到终端安装即可：

1.查看torch和cuda版本

终端运行指令：

python -c 'import torch;print(torch.__version__);print(torch.version.cuda)'

输出结果：

1.13.0+cu117
11.7

对应torch1.13和cuda11.7

1.安装

1.1从预编译包安装

优点是又快又省事。缺点是目前只有mmcv2.0的，1.x的没有。
在这里插入图片描述
这都是预编译好的包，所以安装速度非常快！

1.2 源码编译安装

参考链接：从源码编译 MMCV

2.校验

下载测试文件check_installation.py，然后在当前环境下运行。

运行结果为：

Start checking the installation of mmcv ...
CPU ops were compiled successfully.
CUDA ops were compiled successfully.
mmcv has been installed successfully.

至此就安装完成了~~

报错：from mmcv import Config

需要安装低版本的 MMCV，版本小于2.0.0。


pip install openmim
mim install "mmcv-full<2.0.0"
