如果你遇到了"mmcv CUDA_HOME environment variable is not set. Please set it to your CUDA install root."的问题,这意味着你的CUDA安装路径没有正确设置。你可以按照以下步骤进行设置:
1. 首先,你需要手动从NVIDIA官网[https://developer.nvidia.com/cuda-downloads]下载并安装CUDA驱动程序。这是因为通过Anaconda安装的CUDA不包含完整的包。
2. 安装完成后,你可以检查CUDA是否正确安装并设置了环境变量。你可以在Python中运行以下代码来检查CUDA路径是否设置正确:
```python
import os
print(os.environ.get('CUDA_PATH'))
```
如果你看到打印出的路径,说明CUDA路径已正确设置。如果没有打印出任何东西,说明CUDA路径没有设置。
3. 如果你使用的是Windows系统,并且你的Anaconda环境中没有安装cuda包,你可以在Anaconda命令行中运行以下命令来安装cuda包:
```
conda install -c nvidia cuda
```
这将安装cuda包并自动设置CUDA路径。
通过按照以上步骤进行设置,你应该能够解决"mmcv CUDA_HOME environment variable is not set. Please set it to your CUDA install root."的问题。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
