minrecord is a minimalist Python library to record values in a ML workflow. In particular, it provides functionalities to track the best value, or the most recent values by storing a limiting number of values. It is possible to customize the library e.g. it is possible to define a new logic to track the best value. Below is an example to show how to track the best scalar value when the best value is the maximum value and when the best value is the minimum value.

>>> from minrecord import MaxScalarRecord, MinScalarRecord
>>> record_max = MaxScalarRecord("accuracy")
>>> record_max.update([(0, 42), (None, 45), (2, 46)])
>>> record_max.add_value(40)
>>> record_max.get_best_value()
46
>>> record_min = MinScalarRecord("loss")
>>> record_min.update([(0, 42), (None, 45), (2, 46)])
>>> record_min.add_value(50)
>>> record_min.get_best_value()
42

We highly recommend installing a virtual environment. minrecord can be installed from pip using the following command:

pip install minrecord

To make the package as slim as possible, only the minimal packages required to use minrecord are installed. To include all the dependencies, you can use the following command:

pip install minrecord[all]

Please check the get started page to see how to install only some specific dependencies or other alternatives to install the library. The following is the corresponding minrecord versions and tested dependencies.

Please check the instructions in CONTRIBUTING.md.

Everyone is welcome to contribute to the community. If you have any questions or suggestions, you can submit Github Issues. We will reply to you as soon as possible. Thank you very much.

⚠️ While minrecord is in development stage, no API is guaranteed to be stable from one release to the next. In fact, it is very likely that the API will change multiple times before a stable 1.0.0 release. In practice, this means that upgrading minrecord to a new version will possibly break any code that was using the old version of minrecord.
