ConsoleLogger ¶

class catalyst.loggers.console.ConsoleLogger(log_hparams: bool = False, log_loader_metrics: bool = True, log_epoch_metrics: bool = True)[source]¶

Bases: catalyst.core.logger.ILogger

Console logger for parameters and metrics. Output the metric into the console during experiment.

Parameters

log_hparams – boolean flag to print all hparams to the console (default: False)
log_loader_metrics – boolean flag to print loader metrics to the console (default: True)
log_epoch_metrics – boolean flag to print epoch metrics to the console (default: True)

Note

This logger is used by default by all Runners.

CSVLogger ¶

class catalyst.loggers.csv.CSVLogger(logdir: str, use_logdir_postfix: bool = False)[source]¶

Bases: catalyst.core.logger.ILogger

CSV logger for the metrics storing under .csv file.

Parameters

logdir – path to logdir for the logger
use_logdir_postfix – boolean flag to use extra logs prefix in the logdir

Note

This logger is used by default by dl.Runner and dl.SupervisedRunner in case of specified logdir during runner.train(..., logdir=/path/to/logdir).

Note

This logger is used by default by dl.ConfigRunner and dl.HydraRunner in case of specified logdir in config args.

Notebook API examples:

from catalyst import dl

runner = dl.SupervisedRunner()

NeptuneLogger ¶

class catalyst.loggers.neptune.NeptuneLogger(base_namespace=None, api_token=None, project=None, run=None, **neptune_run_kwargs)[source]¶

Bases: catalyst.core.logger.ILogger

Neptune logger for parameters, metrics, images and other artifacts (videos, audio, model checkpoints, etc.).

Neptune documentation: https://docs.neptune.ai/integrations-and-supported-tools/model-training/catalyst

When the logger is created, link to the run in Neptune will be printed to stdout. It looks like this: https://ui.neptune.ai/common/catalyst-integration/e/CATALYST-1379

To start with Neptune please check Neptune getting-started docs because you will need api_token and project to log your Catalyst runs to.

Note

You can use public api_token ANONYMOUS and set project to common/catalyst-integration for testing without registration.

Parameters

base_namespace – Optional, str, root namespace within Neptune’s run. Default is “experiment”.
api_token – Optional, str. Your Neptune API token. Read more about it in the Neptune installation docs.
project – Optional, str. Name of the project to log runs to. It looks like this: “my_workspace/my_project”.
run – Optional, pass Neptune run object if you want to continue logging to the existing run (resume run). Read more about it here.
neptune_run_kwargs – Optional, additional keyword arguments to be passed directly to the neptune.init() function.

Python API examples:

from catalyst import dl

runner = dl.SupervisedRunner()
runner.train(
    ...
    loggers={
        "neptune": dl.NeptuneLogger(
            project="my_workspace/my_project",
            tags=["pretraining", "retina"],
        )
    }
)

from catalyst import dl

class CustomRunner(dl.IRunner):
    # ...
