MosaicMLLogger

class composer.loggers.MosaicMLLogger(log_interval=60, ignore_keys=None, ignore_exceptions=False)

Log to Mosaic AI Training.

Logs metrics to Mosaic AI Training. Logging only happens on rank 0 every log_interval seconds to avoid performance issues.

When running on Mosaic AI Training, the logger is automatically enabled by Trainer. To disable, the environment variable ‘MOSAICML_PLATFORM’ can be set to False.

Parameters

• log_interval (int, optional) – Buffer log calls more frequent than log_interval seconds to avoid performance issues. Defaults to 60.

• ignore_keys (list[str], optional) –

  A list of keys to ignore when logging. The keys support Unix shell-style wildcards with fnmatch. Defaults to None.

  Example 1: ignore_keys = ["wall_clock/train", "wall_clock/val", "wall_clock/total"] would ignore wall clock metrics.

  Example 2: ignore_keys = ["wall_clock/*"] would ignore all wall clock metrics.

  (default: None)

• ignore_exceptions – Flag to disable logging exceptions. Defaults to False.

log_metadata(metadata, force_flush=False)

Buffer metadata and prefix keys with mosaicml.
