Logger#
- class composer.Logger(state, destinations=None)[source]#
An interface to record training data.
The
Trainer
, instances ofCallback
, and instances ofAlgorithm
invoke the logger to record data such as the epoch, training loss, and custom metrics as provided by individual callbacks and algorithms. This class does not store any data itself; instead, it routes all data to thedestinations
. Each destination (e.g. theFileLogger
,InMemoryLogger
) is responsible for storing the data itself (e.g. writing it to a file or storing it in memory).- Parameters
state (State) โ The training state.
destinations (LoggerDestination | Sequence[LoggerDestination], optional) โ The logger destinations, to where logging data will be sent. (default:
None
)
- destinations#
A sequence of
LoggerDestination
to where logging calls will be sent.- Type
Sequence[LoggerDestination]
- file_artifact(log_level, artifact_name, file_path, *, overwrite=False)[source]#
Log
file_path
as an artifact namedartifact_name
.Both
file_path
andartifact_name
can be specified as format strings. Seeformat_name_with_dist()
for more information.See also
Artifact Logging for notes for file artifact logging.
- Parameters
log_level (str | int | LogLevel) โ The log level, which can be a name, value, or instance of
LogLevel
.artifact_name (str) โ A format string for the name of the artifact.
file_path (str | Path) โ A format string for the file path.
overwrite (bool, optional) โ Whether to overwrite an existing artifact with the same
artifact_name
. (default:False
