 Install [our fork of Grounded-Segment-Anything](https://github.com/hkchengrex/Grounded-Segment-Anything). Follow its instructions.
 
 Grounding DINO installation might fail silently.
 Try `python -c "from groundingdino.util.inference import Model as GroundingDINOModel"`.
 If you get a warning about running on CPU mode only, make sure you have `CUDA_HOME` set during Grounding DINO installation.
