在昇腾NPU容器中从源码安装 detectron2（NPU兼容版本）
确保 mmcv 已安装：
python -c "import mmcv; print(mmcv.__version__)"
关键：在NPU环境下必须从源码安装，不能使用预编译的CUDA版本！
source /opt/conda/bin/activate <conda-env-name>
pip install git+https://github.com/facebookresearch/detectron2.git
python -c "import detectron2; print('detectron2 installed')"
NPU验证（关键步骤）：
python -c "import site; print([p for p in site.getsitepackages() if 'cuda' in p.lower()])"
# 应输出空列表，确保没有安装CUDA版本
如果输出包含 cuda 相关路径，说明安装的是 CUDA 版本，需要卸载并重新从源码安装：
pip uninstall detectron2 -y
pip install git+https://github.com/facebookresearch/detectron2.git
