Build from source

LMDeploy provides prebuilt package that can be easily installed by pip install lmdeploy.

If you have requests to build lmdeploy from source, please clone lmdeploy repository from GitHub, and follow instructions in next sections

git clone --depth=1 https://github.com/InternLM/lmdeploy

Build in Docker (recommended)

We highly advise using the provided docker image for lmdeploy build to circumvent complex environment setup.

The docker image is openmmlab/lmdeploy-builder:cuda11.8. Make sure that docker is installed before using this image.

In the root directory of the lmdeploy source code, please run the following command:

# the home folder of lmdeploy source code
cd lmdeploy
bash builder/manywheel/build_all_wheel.sh

All the wheel files for lmdeploy under py3.8 - py3.11 will be found in the builder/manywheel/cuda11.8_dist directory, such as,

builder/manywheel/cuda11.8_dist/
├── lmdeploy-0.0.12-cp310-cp310-manylinux2014_x86_64.whl
├── lmdeploy-0.0.12-cp311-cp311-manylinux2014_x86_64.whl
├── lmdeploy-0.0.12-cp38-cp38-manylinux2014_x86_64.whl
└── lmdeploy-0.0.12-cp39-cp39-manylinux2014_x86_64.whl

If the wheel file for a specific Python version is required, such as py3.8, please execute:

bash builder/manywheel/build_wheel.sh py38 manylinux2014_x86_64 cuda11.8 cuda11.8_dist

And the wheel file will be found in the builder/manywheel/cuda11.8_dist directory.

You can use pip install to install the wheel file that matches the Python version on your host machine.

Build in localhost (optional)

Firstly, please make sure gcc version is no less than 9, which can be conformed by gcc --version.

Then, follow the steps below to set up the compilation environment:

  • install the dependent packages: 
    pip install -r requirements.txt
apt-get install rapidjson-dev
  • install nccl, and set environment variables: 
    export NCCL_ROOT_DIR=/path/to/nccl
export NCCL_LIBRARIES=/path/to/nccl/lib
  • install openmpi from source: 
    wget https://download.open-mpi.org/release/open-mpi/v4.1/openmpi-4.1.5.tar.gz
tar xf openmpi-4.1.5.tar.gz
cd openmpi-4.1.5
./configure --prefix=/usr/local/openmpi
make -j$(nproc) && make install
export PATH=$PATH:/usr/local/openmpi/bin
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/openmpi/lib
  • build and install lmdeploy libraries: 
    # install ninja
apt install ninja-build
# the home folder of lmdeploy
cd lmdeploy
mkdir build && cd build
sh ../generate.sh
ninja -j$(nproc) && ninja install
  • install lmdeploy python package: 
    cd ..
pip install -e .
