Welcome to the GitHub repo for Taweret, the state of the art Python package for applying Bayesian Model Mixing!
Taweret is a new generalized package to help with applying Bayesian model mixing methods, developed by members of the BAND collaboration, to a wide variety of problems in physics.
At present, this package possesses the following BMM methods:
See Taweret's docs webpage here.
This repository uses submodules. To clone this repository and automatically checkout all the submodules, use
git clone --recursive https://github.com/bandframework/Taweret.git
If you want to limit the size of the repository (this or the submodules), you can use the depth
flag
git clone --depth=1 https://github.com/bandframework/Taweret.git
Inside the directory containing the cloned repository, you then run
git submodule update --init --depth=1
The Trees module depends on OpenMPI. Please ensure OpenMPI is installed with shared/built libraries prior to using the Trees module.
The test suite requires the pytest package to be installed and can be run from the test/
directory. To test the current BMM methods, first install the required packages and then run the following three lines of code:
To installing requirements, first navigate to the Taweret directory. The requirements.txt file is located in the root of this directory. Once in the Taweret directory, then execute the following line of code from the terminal.
pip install -e .
Once all installation is complete, proceed with testing by naviagating to the test/
directory and executing the following three lines of code.
pytest test_bivariate_linear.py
pytest test_gaussian.py
pytest test_trees.py
Taweret also depends on the OpenBT Mixing package in order to execute the trees modulde. This package is built with OpenMPI thus Windows users can work with the trees module using Windows Subsystem for Linux. Installation instructions are shown below.
OpenBT will run within the Windows 10 Windows Subsystem for Linux (WSL) environment. For instructions on installing WSL, please see (https://ubuntu.com/wsl). We recommend installing the Ubuntu 20.04 WSL build. There are also instructions here on keeping your Ubuntu WSL up to date, or installing additional features like X support. Once you have installed the WSL Ubuntu layer, start the WSL Ubuntu shell from the start menu and then you can begin working with Taweret.
GitHub's Codespaces is a great place to test using Taweret. Right now, you can try out Taweret's Bivariate Linear BMM and Multivariate BMM methods there, by following the instructions below.
