Install FlagGems-sglang

For a fresh installation of FlagGems-sglang, follow the steps below.

1. Install build dependencies.

   pip install -U 'scikit-build-core>=0.11' pybind11 ninja cmake
   

2. Clone and install FlagGems-sglang.

   git clone https://github.com/flagos-ai/FlagGems-sglang.git
   cd FlagGems-sglang
   pip install .
   

   For development, use editable installation:

   pip install --no-build-isolation -e .
   

   To run the test suites, install the test dependencies as well:

   pip install -e '.[test]'
   

3. Optionally select the backend explicitly. The runtime detects the device on import; set DNN_VENDOR to force a specific backend instead:

   export DNN_VENDOR=nvidia
   

Verify the installation

python -c "import flaggems_sglang; print(flaggems_sglang.device, flaggems_sglang.vendor_name); print(len(flaggems_sglang.all_registered_ops()), 'operators')"
