Errors and Diagnostics¶
Logging¶
LensKit algorithms and evaluation routines report diagnostic data using the standard Python
logging framework. Loggers are named after the corresponding Python module, and all
live under the lenskit namespace.
Algorithms usually report erroneous or anomalous conditions using Python exceptions and
warnings. Evaluation code, such as that in lenskit.batch, typically reports
such conditions using the logger, as the common use case is to be running them in a script.
