composer.loggers

Modules

composer.loggers.file_logger	Logs to a file or to the terminal.
composer.loggers.in_memory_logger	Logs metrics to dictionary objects that persist in memory throughout training.
composer.loggers.logger_hparams	Logger Hyperparameter classes.
composer.loggers.registry	Logger registry.
composer.loggers.tqdm_logger	Logs metrics to a TQDM progress bar displayed in the terminal.
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 LoggerCallbacks. The LoggerCallback does the actual logging, for example to a file, or Weights and Biases.

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