GroundingDINO and Segment-Anything

I was trying to install Grounded-Segment-Anything but somehow I cannot run it in GPUmode.
After a few hours of searching, I realized the package I installed was CPUmode-only.

• https://github.com/IDEA-Research/Grounded-Segment-Anything
• IDEA-Research/Grounded-Segment-Anything - NameError: name ‘_C’ is not defined #15
• CUDA_HOME environment variable is not set. Please set it to your CUDA install root for pytorch cpp extensions #7757

Therefore the full step to install Grounded-Segment-Anything:

conda install -c conda-forge cudatoolkit-dev -y
export BUILD_WITH_CUDA=True
export CUDA_HOME=$CONDA_PREFIX

git clone https://github.com/IDEA-Research/Grounded-Segment-Anything.git && cd Grounded-Segment-Anything
python -m pip install -e segment_anything
python -m pip install -e GroundingDINO
