cait 1.2.2

Cryogenic Artificial Intelligence Tools - A Python Package for the Data Analysis of Rare Event Search Experiments with Machine Learning.

Cait (Cryogenic Artificial Intelligence Tools) is a Python 3 software package for the machine learning based analysis of raw data from cryogenic dark matter experiments. It is tailored to the needs of the CRESST and COSINUS experiment, but applicable to other, similar data structures.

Documentation: https://cait.readthedocs.io/

Source Code: https://github.com/fewagner/cait

Bug Report: https://github.com/fewagner/cait/issues

Installation

Cait is hosted on the Python package index.

$ pip install cait

You can now import the library in Python, e.g.

import cait as ai

Note

Important Note for JupyterHub on computing clusters

In the past, many users experienced issues with our interactive plotting tools which are based on plotly and ipywidgets. These problems were due to version mismatches between the plotly/ipywidgets packages and their corresponding JupyterLab extensions (which are automatically installed alongside the packages).

To not run into such issues in the first place, we recommend one of the following approaches:

• Install cait in the base environment of your computing cluster’s JupyterLab.

• Install it in a virtual environment (because you want or have to) is also possible but you will have to make sure that the same plotly/ipywidgets versions (which are installed as dependencies of cait) are also present in the base environment. A good practice to ensure this is to always pip-upgrade plotly/ipywidgets to the latest version in both environments. Note that you will potentially have to match these versions every time you upgrade cait.

Lastly, remember to restart JupyterHub completely (not just the kernel) for the changes to take effect.

To learn how to add a virtual environment as a kernel to jupyterlab, refer to this great reference.
