Geneval MMCV Setup

This setup is optional. Only install these packages if your workflow needs the Geneval/OpenMMLab stack.

Why separate?

mmcv/mmdet have CUDA build constraints and are not required for core UniRL training pipelines.

Recommended versions

• mmcv tag: v1.7.2
• mmdetection branch: 2.x (currently 2.28.2 in our validated env)

These versions match the validated local setup used in this repository.

Install steps

Run from any working directory (examples use ~/mmgrpo):

pip install -U openmim
mim install mmengine

cd ~/mmgrpo
git clone https://github.com/open-mmlab/mmcv.git
cd mmcv
git checkout tags/v1.7.2
MMCV_WITH_OPS=1 FORCE_CUDA=1 pip install -e . -v
cd ..

git clone https://github.com/open-mmlab/mmdetection.git
cd mmdetection
git checkout 2.x
pip install -e . -v
cd ..

Sanity check

python -c "import mmcv, mmdet; print('mmcv', mmcv.__version__); print('mmdet', mmdet.__version__); from mmcv.ops import nms; print('mmcv.ops ok')"

Expected:

• mmcv reports 1.7.2
• mmdet reports a 2.x version (e.g., 2.28.2)
• mmcv.ops ok prints without import errors
