Run - Weights & Biases Documentation

`class` `Run`

A unit of computation logged by W&B. Typically, this is an ML experiment. Call wandb.init() to create a new run. wandb.init() starts a new run and returns a wandb.Run object. Each run is associated with a unique ID (run ID). W&B recommends using a context (with statement) manager to automatically finish the run. For distributed training experiments, you can either track each process separately using one run per process or track all processes to a single run. See Log distributed training experiments for more information. You can log data to a run with wandb.Run.log(). Anything you log using wandb.Run.log() is sent to that run. See Create an experiment or wandb.init API reference page or more information. There is a another Run object in the wandb.apis.public namespace. Use this object is to interact with runs that have already been created. Attributes:

summary: (Summary) A summary of the run, which is a dictionary-like object. For more information, see
[Log summary metrics](https: //docs.wandb.ai/models/track/log/log-summary/).

Examples: Create a run with wandb.init():

import wandb

# Start a new run and log some data
# Use context manager (`with` statement) to automatically finish the run
with wandb.init(entity="entity", project="project") as run:
    run.log({"accuracy": acc, "loss": loss})

`property` Run.config

Config object associated with this run. Returns:

wandb_config.Config: The config property value.

`property` Run.config_static

Static config object associated with this run. Returns:

wandb_config.ConfigStatic: The config_static property value.

`property` Run.dir

The directory where files associated with the run are saved. Returns:

str: The dir property value.

`property` Run.disabled

True if the run is disabled, False otherwise. Returns:

bool: The disabled property value.

`property` Run.entity

The name of the W&B entity associated with the run. Entity can be a username or the name of a team or organization. Returns:

str: The entity property value.

`property` Run.group

Returns the name of the group associated with this run. Grouping runs together allows related experiments to be organized and visualized collectively in the W&B UI. This is especially useful for scenarios such as distributed training or cross-validation, where multiple runs should be viewed and managed as a unified experiment. In shared mode, where all processes share the same run object, setting a group is usually unnecessary, since there is only one run and no grouping is required. Returns:

str: The group property value.

`property` Run.id

Identifier for this run. Returns:

str: The id property value.

`property` Run.job_type

Name of the job type associated with the run. View a run’s job type in the run’s Overview page in the W&B App. You can use this to categorize runs by their job type, such as “training”, “evaluation”, or “inference”. This is useful for organizing and filtering runs in the W&B UI, especially when you have multiple runs with different job types in the same project. For more information, see Organize runs. Returns:

str: The job_type property value.

`property` Run.name

Display name of the run. Display names are not guaranteed to be unique and may be descriptive. By default, they are randomly generated. Returns:

str | None: The name property value.

`property` Run.notes

Notes associated with the run, if there are any. Notes can be a multiline string and can also use markdown and latex equations inside $$, like $x + 3$ . Returns:

str | None: The notes property value.

`property` Run.offline

True if the run is offline, False otherwise. Returns:

bool: The offline property value.

`property` Run.path

Path to the run. Run paths include entity, project, and run ID, in the format entity/project/run_id. Returns:

str: The path property value.

`property` Run.project

Name of the W&B project associated with the run. Returns:

str: The project property value.

`property` Run.project_url

URL of the W&B project associated with the run, if there is one. Offline runs do not have a project URL. Returns:

str | None: The project_url property value.

True if the run was resumed, False otherwise. Returns:

bool: The resumed property value.

`property` Run.settings

A frozen copy of run’s Settings object. Returns:

Settings: The settings property value.

Identifier for the sweep associated with the run, if there is one. Returns:

str | None: The sweep_id property value.

`property` Run.sweep_url

URL of the sweep associated with the run, if there is one. Offline runs do not have a sweep URL. Returns:

str | None: The sweep_url property value.

`property` Run.tags

Tags associated with the run, if there are any. Returns:

tuple | None: The tags property value.

`property` Run.url

The url for the W&B run, if there is one. Offline runs will not have a url. Returns:

str | None: The url property value.

title: The title of the alert, must be less than 64 characters long.
text: The text body of the alert.
level: The alert level to use, either: INFO, WARN, or ERROR.
wait_duration: The time to wait (in seconds) before sending another alert with this title.

`method` `Run.define_metric`

define_metric(
    name: 'str',
    step_metric: 'str | wandb_metric.Metric | None' = None,

) → wandb_metric.Metric

Customize metrics logged with wandb.Run.log(). Args:

name: The name of the metric to customize.
step_metric: The name of another metric to serve as the X-axis for this metric in automatically generated charts.
step_sync: Automatically insert the last value of step_metric into wandb.Run.log() if it is not provided explicitly. Defaults to True if step_metric is specified.
hidden: Hide this metric from automatic plots.
summary: Specify aggregate metrics added to summary. Supported aggregations include “min”, “max”, “mean”, “last”, “first”, “best”, “copy” and “none”. “none” prevents a summary from being generated. “best” is used together with the goal parameter, “best” is deprecated and should not be used, use “min” or “max” instead. “copy” is deprecated and should not be used.
goal: Specify how to interpret the “best” summary type. Supported options are “minimize” and “maximize”. “goal” is deprecated and should not be used, use “min” or “max” instead.
overwrite: If false, then this call is merged with previous define_metric calls for the same metric by using their values for any unspecified parameters. If true, then unspecified parameters overwrite values specified by previous calls.

Returns: An object that represents this call but can otherwise be discarded.

`method` `Run.display`

Display this run in Jupyter.

`method` `Run.finish`

finish(exit_code: 'int | None' = None, quiet: 'bool | None' = None) → None

Finish a run and upload any remaining data. Marks the completion of a W&B run and ensures all data is synced to the server. The run’s final state is determined by its exit conditions and sync status. Run States:

Running: Active run that is logging data and/or sending heartbeats.
Crashed: Run that stopped sending heartbeats unexpectedly.
Finished: Run completed successfully (exit_code=0) with all data synced.
Failed: Run completed with errors (exit_code!=0).
Killed: Run was forcibly stopped before it could finish.

Args:

exit_code: Integer indicating the run’s exit status. Use 0 for success, any other value marks the run as failed.
quiet: Deprecated. Configure logging verbosity using wandb.Settings(quiet=...).

`method` `Run.finish_artifact`

finish_artifact(
    artifact_or_path: 'Artifact | str',
    name: 'str | None' = None,
    type: 'str | None' = None,
    aliases: 'list[str] | None' = None,
    distributed_id: 'str | None' = None
) → Artifact

Finishes a non-finalized artifact as output of a run. Subsequent “upserts” with the same distributed ID will result in a new version. Args:

artifact_or_path: A path to the contents of this artifact, can be in the following forms:
- /local/directory
- /local/directory/file.txt
- s3://bucket/path You can also pass an Artifact object created by calling wandb.Artifact.
name: An artifact name. May be prefixed with entity/project. Valid names can be in the following forms:
- name:version
- name:alias
- digest This will default to the basename of the path prepended with the current run id if not specified.
type: The type of artifact to log, examples include dataset, model
aliases: Aliases to apply to this artifact, defaults to ["latest"]
distributed_id: Unique string that all distributed jobs share. If None, defaults to the run’s group name.

Returns: An Artifact object.

`method` `Run.link_artifact`

link_artifact(
    artifact: 'Artifact',
    target_path: 'str',
    aliases: 'list[str] | None' = None
) → Artifact

Link the given artifact to a portfolio (a promoted collection of artifacts). Linked artifacts are visible in the UI for the specified portfolio. Args:

artifact: the (public or local) artifact which will be linked
target_path: str - takes the following forms: {portfolio}, {project}/{portfolio}, or {entity}/{project}/{portfolio}
aliases: List[str] - optional alias(es) that will only be applied on this linked artifact inside the portfolio. The alias “latest” will always be applied to the latest version of an artifact that is linked.

Returns: The linked artifact.

`method` `Run.link_model`

link_model(
    path: 'StrPath',
    registered_model_name: 'str',
    name: 'str | None' = None,
    aliases: 'list[str] | None' = None
) → Artifact | None

Log a model artifact version and link it to a registered model in the model registry. Linked model versions are visible in the UI for the specified registered model. This method will:

Check if ‘name’ model artifact has been logged. If so, use the artifact version that matches the files located at ‘path’ or log a new version. Otherwise log files under ‘path’ as a new model artifact, ‘name’ of type ‘model’.
Check if registered model with name ‘registered_model_name’ exists in the ‘model-registry’ project. If not, create a new registered model with name ‘registered_model_name’.
Link version of model artifact ‘name’ to registered model, ‘registered_model_name’.
Attach aliases from ‘aliases’ list to the newly linked model artifact version.

Args:

path: (str) A path to the contents of this model, can be in the following forms:
- /local/directory
- /local/directory/file.txt
- s3://bucket/path
registered_model_name: The name of the registered model that the model is to be linked to. A registered model is a collection of model versions linked to the model registry, typically representing a team’s specific ML Task. The entity that this registered model belongs to will be derived from the run.
name: The name of the model artifact that files in ‘path’ will be logged to. This will default to the basename of the path prepended with the current run id if not specified.
aliases: Aliases that will only be applied on this linked artifact inside the registered model. The alias “latest” will always be applied to the latest version of an artifact that is linked.

Raises:

AssertionError: If registered_model_name is a path or if model artifact ‘name’ is of a type that does not contain the substring ‘model’.
ValueError: If name has invalid special characters.

Returns: The linked artifact if linking was successful, otherwise None.

`method` `Run.log`

log(
    data: 'dict[str, Any]',
    step: 'int | None' = None,
    commit: 'bool | None' = None
) → None

Upload run data. Use log to log data from runs, such as scalars, images, video, histograms, plots, and tables. See Log objects and media for code snippets, best practices, and more. Basic usage:

import wandb

with wandb.init() as run:
     run.log({"train-loss": 0.5, "accuracy": 0.9})

The previous code snippet saves the loss and accuracy to the run’s history and updates the summary values for these metrics. Visualize logged data in a workspace at wandb.ai, or locally on a self-hosted instance of the W&B app, or export data to visualize and explore locally, such as in a Jupyter notebook, with the Public API. Logged values don’t have to be scalars. You can log any W&B supported Data Type such as images, audio, video, and more. For example, you can use wandb.Table to log structured data. See Log tables, visualize and query data tutorial for more details. W&B organizes metrics with a forward slash (/) in their name into sections named using the text before the final slash. For example, the following results in two sections named “train” and “validate”:

with wandb.init() as run:
     # Log metrics in the "train" section.
     run.log(
         {
             "train/accuracy": 0.9,
             "train/loss": 30,
             "validate/accuracy": 0.8,
             "validate/loss": 20,
         }
     )

Only one level of nesting is supported; run.log({"a/b/c": 1}) produces a section named “a/b”. run.log() is not intended to be called more than a few times per second. For optimal performance, limit your logging to once every N iterations, or collect data over multiple iterations and log it in a single step. By default, each call to log creates a new “step”. The step must always increase, and it is not possible to log to a previous step. You can use any metric as the X axis in charts. See Custom log axes for more details. In many cases, it is better to treat the W&B step like you’d treat a timestamp rather than a training step.

with wandb.init() as run:
     # Example: log an "epoch" metric for use as an X axis.
     run.log({"epoch": 40, "train-loss": 0.5})

It is possible to use multiple wandb.Run.log() invocations to log to the same step with the step and commit parameters. The following are all equivalent:

with wandb.init() as run:
     # Normal usage:
     run.log({"train-loss": 0.5, "accuracy": 0.8})
     run.log({"train-loss": 0.4, "accuracy": 0.9})

     # Implicit step without auto-incrementing:
     run.log({"train-loss": 0.5}, commit=False)
     run.log({"accuracy": 0.8})
     run.log({"train-loss": 0.4}, commit=False)
     run.log({"accuracy": 0.9})

     # Explicit step:
     run.log({"train-loss": 0.5}, step=current_step)
     run.log({"accuracy": 0.8}, step=current_step)
     current_step += 1
     run.log({"train-loss": 0.4}, step=current_step)
     run.log({"accuracy": 0.9}, step=current_step)

Args:

data: A dict with str keys and values that are serializable
Python objects including: int, float and string; any of the wandb.data_types; lists, tuples and NumPy arrays of serializable Python objects; other dicts of this structure.
step: The step number to log. If None, then an implicit auto-incrementing step is used. See the notes in the description.
commit: If true, finalize and upload the step. If false, then accumulate data for the step. See the notes in the description. If step is None, then the default is commit=True; otherwise, the default is commit=False.

    base_path: 'str | os.PathLike | None' = None,
    policy: 'PolicyName' = 'live'
) → bool | list[str]

Sync one or more files to W&B. Relative paths are relative to the current working directory. A Unix glob, such as “myfiles/*”, is expanded at the time save is called regardless of the policy. In particular, new files are not picked up automatically. A base_path may be provided to control the directory structure of uploaded files. It should be a prefix of glob_str, and the directory structure beneath it is preserved. When given an absolute path or glob and no base_path, one directory level is preserved as in the example above. Args:

glob_str: A relative or absolute path or Unix glob.
base_path: A path to use to infer a directory structure; see examples.
policy: One of live, now, or end.
- live: upload the file as it changes, overwriting the previous version
- now: upload the file once now
- end: upload file when the run ends

Returns: Paths to the symlinks created for the matched files. For historical reasons, this may return a boolean in legacy code.

import wandb

run = wandb.init()

run.save("these/are/myfiles/*")
# => Saves files in a "these/are/myfiles/" folder in the run.

run.save("these/are/myfiles/*", base_path="these")
# => Saves files in an "are/myfiles/" folder in the run.

run.save("/User/username/Documents/run123/*.txt")
# => Saves files in a "run123/" folder in the run. See note below.

run.save("/User/username/Documents/run123/*.txt", base_path="/User")
# => Saves files in a "username/Documents/run123/" folder in the run.

run.save("files/*/saveme.txt")
# => Saves each "saveme.txt" file in an appropriate subdirectory
#    of "files/".

# Explicitly finish the run since a context manager is not used.

artifact_or_name: The name of the artifact to use. May be prefixed with the name of the project the artifact was logged to (“<entity>” or “<entity>/<project>”). If no entity is specified in the name, the Run or API setting’s entity is used. Valid names can be in the following forms
- name:version
- name:alias
type: The type of artifact to use.
aliases: Aliases to apply to this artifact
use_as: This argument is deprecated and does nothing.

Returns: An Artifact object. Examples:

import wandb

run = wandb.init(project="<example>")

# Use an artifact by name and alias
artifact_a = run.use_artifact(artifact_or_name="<name>:<alias>")

# Use an artifact by name and version
artifact_b = run.use_artifact(artifact_or_name="<name>:v<version>")

# Use an artifact by entity/project/name:alias
artifact_c = run.use_artifact(
   artifact_or_name="<entity>/<project>/<name>:<alias>"
)

# Use an artifact by entity/project/name:version
artifact_d = run.use_artifact(
   artifact_or_name="<entity>/<project>/<name>:v<version>"
)

# Explicitly finish the run since a context manager is not used.
run.finish()

`method` `Run.use_model`

use_model(name: 'str') → FilePathStr

Download the files logged in a model artifact ‘name’. Args:

name: A model artifact name. ‘name’ must match the name of an existing logged model artifact. May be prefixed with entity/project/. Valid names can be in the following forms
- model_artifact_name:version
- model_artifact_name:alias

Returns:

path (str): Path to downloaded model artifact file(s).

Raises:

AssertionError: If model artifact ‘name’ is of a type that does not contain the substring ‘model’.

`method` `Run.watch`

watch(
    models: 'torch.nn.Module | Sequence[torch.nn.Module]',
    criterion: 'torch.F | None' = None,
    log: "Literal['gradients', 'parameters', 'all'] | None" = 'gradients',
    log_freq: 'int' = 1000,
    idx: 'int | None' = None,
    log_graph: 'bool' = False
) → None

Hook into given PyTorch model to monitor gradients and the model’s computational graph. This function can track parameters, gradients, or both during training. Args:

models: A single model or a sequence of models to be monitored.
criterion: The loss function being optimized (optional).
log: Specifies whether to log “gradients”, “parameters”, or “all”. Set to None to disable logging. (default=“gradients”).
log_freq: Frequency (in batches) to log gradients and parameters. (default=1000)
idx: Index used when tracking multiple models with wandb.watch. (default=None)
log_graph: Whether to log the model’s computational graph. (default=False)

Raises: ValueError: If wandb.init() has not been called or if any of the models are not instances of torch.nn.Module.
