Features
Install mmdetection3d (3D object detection library) in an Ascend NPU container
Prerequisites
- mmcv is installed
- mmsegmentation is installed (required by mmdet3d)
- Ascend CANN and torch_npu are installed in the container
- The working directory is mounted
Usage
Step 1: Confirm prerequisites
Ensure mmcv is installed:
python -c "import mmcv; print(mmcv.__version__)"
Step 2: Install mmsegmentation
mmdet3d depends on mmsegmentation; choose according to version:
Recommended version(compatible with mmcv 1.7.x):
pip install mmsegmentation==0.30.0
Step 3: Clone the mmdetection3d repository
Choose according to network conditions:
Direct server connection：
git clone -b v1.0.0rc4 https://github.com/open-mmlab/mmdetection3d.git
Server network timeout: configure a proxy or clone locally and transfer via scp
# 方案1：配置代理
export http_proxy=http://proxy:port
export https_proxy=http://proxy:port
git clone -b v1.0.0rc4 https://github.com/open-mmlab/mmdetection3d.git
# 方案2：本地克隆后传输（仍使用GitHub链接）
# 本地执行
git clone -b v1.0.0rc4 https://github.com/open-mmlab/mmdetection3d.git
scp -r mmdetection3d user@server:/target/path/
Important: always use the official GitHub link, do not use mirror sites.
Step 4: Apply patch (if any)
cd mmdetection3d
cp /path/to/DrivingSDK/model_examples/BEVFormer/mmdet3d_config.patch .
git apply --reject mmdet3d_config.patch
Step 5: Install
source /opt/conda/bin/activate <conda-env-name>
pip install -e .
Step 6: Verify installation
python -c "import mmdet3d; print(mmdet3d.__version__)"
NPU verification：
python -c "import site; print([p for p in site.getsitepackages() if 'cuda' in p.lower()])"

FAQ
- mmsegmentation version: must use version 0.30.0, which is compatible with mmcv 1.7.x
- import mmseg fails: ensure mmsegmentation is installed correctly
- patch fails: skip non-critical patches or handle manually
Decision guidance
Ask the user：
- Is mmcv already installed?
- Which version of mmsegmentation should be used?
- Can the server network access GitHub?
- Do any specific patches need to be applied?
