The tensiometer package is a collection of tools to test the level of agreement/disagreement between different posterior distributions.
The best way to get up to speed is to read through the worked example full worked example that you can run online! There's also a documented example of non-Gaussian tension estimates between DES Y1 and Planck 18.
The tensiometer package is available on PyPI and can be easily installed with:
pip install tensiometer
Alternatively one can download the source code from github:
git clone https://github.com/mraveri/tensiometer.git
and install it locally with the shortcut:
make install
You can test that the code is working properly by using:
make test
Uses mostly standard python packages and GetDist.
