Installation¶

From PyPI¶

pip install dlslime==0.0.3

The PyPI package is built with the default CMake flags. Build from source when you need optional transports or local C++ changes.

git clone https://github.com/DeepLink-org/DLSlime.git
cd DLSlime
pip install -v --no-build-isolation -e .

Pass CMake flags through the environment when enabling optional components:

BUILD_NVLINK=ON BUILD_TORCH_PLUGIN=ON \
  pip install -v --no-build-isolation -e .

For a pure C++ build:

cmake -S . -B build -GNinja -DBUILD_PYTHON=OFF -DBUILD_RDMA=ON
cmake --build build
