composer.loggers

Modules

composer.loggers.file_logger	Logs to a file.
composer.loggers.in_memory_logger	Logs metrics to dictionary objects that persist in memory throughout training.
composer.loggers.logger	Base classes, functions, and variables for logger.
composer.loggers.logger_destination	Base class for logger callback.
composer.loggers.logger_hparams	Logger Hyperparameter classes.
composer.loggers.object_store_logger	Log artifacts to an object store.
composer.loggers.progress_bar_logger	Logs metrics to the console and show a progress bar.
composer.loggers.wandb_logger	Log to Weights and Biases (https://wandb.ai/)

Loggers to store metrics and artifacts.

In Composer, algorithms and callbacks can make calls to the Logger, which then routes the calls to the appropriate LoggerDestinations. The LoggerDestination does the actual logging, for example to a file, or Weights and Biases.

See the LoggerDestination documentation for an example of how to define a custom logger and use it when training.
