安装mmcv-full时报错

• 报错ERROR: Could not build wheels for mmcv-full, which is required to install pyproject.toml-based projects
• 详细报错信息如下：

      copying mmcv/ops/csrc/tensorrt/plugins/trt_scatternd_kernel.cu -> build/lib.linux-x86_64-3.8/mmcv/ops/csrc/tensorrt/plugins
      running build_ext
      error: [Errno 2] No such file or directory: ':/usr/local/cuda-12.2/bin/nvcc'
      [end of output]

  note: This error originates from a subprocess, and is likely not a problem with pip.
  ERROR: Failed building wheel for mmcv-full
  Running setup.py clean for mmcv-full
Failed to build mmcv-full
ERROR: Could not build wheels for mmcv-full, which is required to install pyproject.toml-based projects

• 往上寻找最开始的报错点，为这一句：

error: [Errno 2] No such file or directory: ':/usr/local/cuda-12.2/bin/nvcc'
      [end of output]

• 参考资料得出，路径前不该有：，导致虽然/usr/local/cuda-12.2/bin/路径下有nvcc文件，但是仍然找不到
• 输入以下代码，临时添加cuda环境变量（仅供这次ssh远程登陆时使用）
• 注意，不管你的cuda版本为多少，都原封不动的输入以下代码

export CUDA_HOME=/usr/local/cuda

• 之后再次运行pip install mmcv-full即可
