You may choose one of two methods to install Treelite on your system:

Download binary releases from Conda

Treelite is also available on Conda.

conda install -c conda-forge treelite

to install the Treelite package. See to check the available platforms.

Compile Treelite from the source

Installation consists of two steps:

  1. Build the shared libraries from C++ code (See the note below for the list.)

  2. Install the Python package.

Linux / other UNIX

To get started, clone Treelite repo from GitHub.

git clone
cd treelite

The next step is to build the shared libraries.

1-1. Compiling shared libraries on Linux and MacOS

Here, we use CMake to generate a Makefile:

mkdir build
cd build
cmake ..

Once CMake finished running, simply invoke GNU Make to obtain the shared libraries.


The compiled libraries will be under the build/ directory.


Compiling Treelite with multithreading on MacOS

Treelite requires the presence of OpenMP runtime. To install OpenMP runtime on a Mac OSX system, run the following command:

brew install libomp

1-2. Compiling shared libraries on Windows

We can use CMake to generate a Visual Studio project. The following snippet assumes that Visual Studio 2022 is installed. Adjust the version depending on the copy that’s installed on your system.

mkdir build
cd build
cmake .. -G"Visual Studio 17 2022" -A x64


Visual Studio 2019 or newer is required

Treelite uses the C++17 standard. Ensure that you have Visual Studio version 2019 or newer.

Once CMake finished running, open the generated solution file (treelite.sln) in Visual Studio. From the top menu, select Build > Build Solution.

2. Installing Python package

The Python package is located at the python subdirectory. Run Pip to install the Python package. The Python package will re-use the native library built in Step 1.

cd python
pip install .  # will re-use
