• Config editor for W&B LEET TUI (wandb beta leet config command). (@dmitryduev in #11327)
• owner property on wandb.apis.public.Project to access the project owner's user information. (@jacobromero in #11278)

Changed

• Python 3.8 is no longer supported (@tonyyli-wandb in #11198, #11290, #11164)

Fixed

• Sweep agents now exit gracefully when the sweep is deleted, instead of running indefinitely with repeated 404 errors (@domphan-wandb in #11226)

What's Changed

Added

• wandb.Api() now supports Federated Auth (JWT based authentication). (@RyanBuccellato in #11243)

Fixed

• Refresh presigned download url when it expires during artifact file downloads. (@pingleiwandb in #11242)

What's Changed

Notable Changes

Runs created with wandb==0.24.0 may fail to upload some data, which this release fixes. Missing data is stored in the run's .wandb file and can be reuploaded with wandb sync.

Added

• download_history_exports in api.Run class to download exported run history in parquet file format (@jacobromero in #11094)

Changed

• When a settings file (such as ./wandb/settings or ~/.config/wandb/settings) contains an invalid setting, all settings files are ignored and an error is printed (@timoffex in #11207)

Fixed

• After wandb login --host <invalid-url>, using wandb login --host <valid-url> works as usual (@timoffex in #11207)
  • Regression introduced in 0.24.0
• wandb beta sync correctly loads credentials (@timoffex in #11231)
  • Regression introduced in 0.24.0
  • Caused wandb beta sync to get stuck on Syncing...
• Fixed occasional unuploaded data in 0.24.0 (@timoffex in #11249)
  • All data is stored in the run's .wandb file and can be reuploaded with wandb sync

⚠️ This release has been yanked from PyPI.
Do not use this version. Runs created with wandb==0.24.0 may in rare cases silently fail to upload data. Upgrade immediately to v0.24.1, which fixes this issue. If you've already used this version, missing data is stored in the run's .wandb file and can be recovered with wandb sync.

What's Changed

Notable Changes

This version removes the legacy, deprecated wandb.beta.workflows module, including its log_model()/use_model()/link_model() functions. This is formally a breaking change.

Added

• wandb agent and wandb.agent() now accept a forward_signals flag (CLI: --forward-signals/-f) to relay SIGINT/SIGTERM and other catchable signals from the agent to its sweep child runs, enabling cleaner shutdowns when you interrupt an agent process (@KyleGoyette, @domphan-wandb in #9651)
• wandb beta sync now supports a --live option for syncing a run while it's being logged (@timoffex in #11079)

Removed

• Removed the deprecated wandb.beta.workflows module, including its log_model(), use_model(), and link_model() functions, and whose modern successors are the Run.log_artifact, Run.use_artifact, and Run.link_artifact methods, respectively (@tonyyli-wandb in [TODO: PR link])

Fixed

• Fixed Run.__exit__ type annotations to accept None values, which are passed when no exception is raised (@moldhouse in #11100)
• Fixed Invalid Client ID digest error when creating artifacts after calling random.seed(). Client IDs could collide when random state was seeded deterministically. (@pingleiwandb in #11039)
• Fixed CLI error when listing empty artifacts (@ruhiparvatam in #11157)
• Fixed regression for calling api.run() on a Sweeps run (@willtryagain in #11088 and @kelu-wandb in #11097)
• Fixed the "View run at" message printed at the end of a run which sometimes did not include a URL (@timoffex in #11113)
• Runs queried from wandb.Api() now display a string representation in VSCode notebooks instead of a broken HTML window (@jacobromero in #11040)

What's Changed

Added

• Regex support in metrics and run overview filters in W&B LEET TUI (@dmitryduev in #10919)

• The automations API now supports creating and editing automations that trigger on run states (@tonyyli-wandb in #10848)
• The automations API now support basic zscore automation events (@matthoare117-wandb in #10931)
• Simplified the syntax for creating z-score metric automation triggers in the automations API (@matthoare117-wandb in #10953)

  • wandb.Api() has only ever worked using an API key

Deprecated

• Anonymous mode, including the anonymous setting, the WANDB_ANONYMOUS environment variable, wandb.init(anonymous=...), wandb login --anonymously and wandb.login(anonymous=...) is deprecated and will emit warnings (@timoffex in #10909)

Fixed

• wandb.Image() no longer prints a deprecation warning (@jacobromero in #10880)
• Registry.description and ArtifactCollection.description no longer reject empty strings (@tonyyli-wandb in #10891)
• Instantiating Artifact objects is now significantly faster (@tonyyli-wandb in #10819)
• wandb.Run.save() now falls back to hardlinks and, if needed, copying (downgrading the 'live' file policy to 'now', if applicable) when symlinks are disabled or unavailable (e.g., cross‑volume or no Developer Mode on Windows) (@dmitryduev in #10894)
• Artifact collection aliases are now fetched lazily on accessing ArtifactCollection.aliases instead of on instantiating ArtifactCollection, improving performance of Api.artifact_collections(), Api.registries().collections(), etc. (@tonyyli-wandb in #10731)
• Use explicitly provided API key in wandb.init(settings=wandb.Settings(api_key="...")) for login. Use the key from run when logging artifacts via run.log_artifact (@pingleiwandb in #10914)

• The numerator for file upload progress no longer occasionally exceeds the total file size (@timoffex in #10812)
• Artifact.link() now logs unsaved artifacts instead of raising an error, consistent with the behavior of Run.link_artifact() (@tonyyli-wandb in https://github.com/wandb/wandb/10822)
• Automatic code saving now works when running ipython notebooks in VSCode's Jupyter notebook extension (@jacobromero in #10746)
• Logging an artifact with infinite floats in Artifact.metadata now raises a ValueError early, instead of waiting on request retries to time out (@tonyyli-wandb in #10845).

What's Changed

Added

• Settings console_chunk_max_seconds and console_chunk_max_bytes for size- and time-based multipart console logs file chunking (@dmitryduev in #10162)
• Registry API query methods (Api.registries(), Registry.{collections,versions}(), Api.registries().{collections,versions}()) now accept a per_page keyword arg to override the default batch size for paginated results (@tonyyli-wandb in #10713).

• Fixed a rare deadlock in console_capture.py (@timoffex in #10683)
  • If you dump thread tracebacks during the deadlock and see the wandb-AsyncioManager-main thread stuck on a line in console_capture.py: this is now fixed.
• Fixed an issue where TensorBoard sync would sometimes stop working if the tfevents files were being written live (@timoffex in #10625)
• Artifact.manifest delays downloading and generating the download URL for the artifact manifest until it's first used. If the manifest has not been locally modified, Artifact.size and Artifact.digest can return without waiting to fetch the full manifest (@tonyyli-wandb in #10680)
• Fixed uploading GCS folder references via artifact.add_reference (@amusipatla-wandb in #10679)
• The SDK now correctly infers notebooks paths in Jupyter sessions, using th server's root directory, so code saving works in subdirectories (e.g. code/nested/.ipynb) (@jacobromero in #10709)

What's Changed

Fixed

• Possibly fixed some cases where the output.log file was not being uploaded (@timoffex in #10620)

What's Changed

Added

• Optimize artifacts downloads re-verification with checksum caching (@thanos-wandb in #10157)

Fixed

• Api.artifact_exists() and Api.artifact_collection_exists() now raise on encountering timeout errors, rather than (potentially erroneously) returning False. (@tonyyli-wandb in #10591)
