-### Using the NeMo-Gym Container with VLM or Audio/Video Benchmarks
-
-The NeMo-Gym container omits packages with bundled codec libraries
-(`opencv-python-headless`, `torchvision`, `torchaudio`) to avoid shipping
-royalty-bearing binaries. If you are running VLM or audio/video benchmarks
-inside the container, restore them first:
-
-```bash
-bash docker/install_codec_deps.sh
-```
-
-This installs the packages at the same versions used during the container
-build. It is safe to run multiple times.
-
