wandb 0.28.1

v0.28.1

on Python PyPI

What's Changed

Notable Changes

This version drops support for protobuf v4, and requires protobuf v5 or newer.
This version drops compatibility with server versions older than 0.70.0.

Added

• New filters parameter to Api().project().sweeps() matching the runs filter format (@kmikowicz-wandb in #12059)
• Added Run.stop() to the public API (wandb.Api().run(...).stop()) to programmatically request that an active run stop gracefully, like the "Stop run" button in the W&B App UI (@dmitryduev in #12159)
• Added wandb.Api().organization() to fetch an Organization by name, or the current default organization for the user (@tonyyli-wandb in #12196)

Changed

• Remove temporary Unix socket files and directories on shutdown (@geoffhardy in #12058)
• wandb beta sync now skips online runs by default like wandb sync (@timoffex in #12087)
• wandb sync now routes to wandb beta sync for supported parameter sets (@timoffex in #12093)
  • Restore original behavior with --legacy
• Dropped support for protobuf v4 (@jacobromero in #12115)
• wandb.sandbox now defaults serverless sandboxes to a 12-hour max lifetime (max_lifetime_seconds=43200); override per sandbox with max_lifetime_seconds or via SandboxDefaults (@nicholaspun-wandb in #12136)
• wandb.Api().runs() now raises a RunNotFoundError when unable to load data for a run, such as when a run is deleted prior to fully loading run data (@jacobromero in https://app.graphite.com/github/pr/wandb/wandb/12176)
• wandb.save now has an option glob=False that disables glob expansion (*, ?, [...]) for file paths; updated docs for improved explanation (@geoffhardy in #12192)

Removed

• Removed legacy fallback implementations for downloading artifact files on older EOL W&B Server releases. The following will no longer work on EOL servers: Artifact.files() and Artifact.download() on any artifact, as well as Artifact.get_entry() / Artifact.get_path() file downloads on non-reference artifacts. (@tonyyli-wandb in #12109)
  • To continue using these operations, upgrade your W&B Server to v0.70.0 or newer.
• Removed legacy fallback implementations for fetching an artifact by name on older EOL W&B Server releases. The following will no longer work on EOL servers: wandb.Api().artifact(...) and other methods that fetch artifact(s) by their path. (@tonyyli-wandb in #12112)
  • To continue using these operations, upgrade your W&B Server to v0.70.0 or newer.
• Removed the GitPython dependency. Git metadata is collected by invoking the git executable directly; the GIT_PYTHON_GIT_EXECUTABLE environment variable is still honored for locating it (@dmitryduev in #11983)

Fixed

• Saving a linked registry artifact (for example, when adding an alias) no longer fails when the caller lacks write access to the source project (@ibindlish in #12075)
• np.float16/np.float32 NaN values logged with Run.log() are now recorded as NaN instead of being silently dropped, matching np.float64 and native float (@dmitryduev in #12116)
• Run.upload_file() (via wandb.Api().run(...)) now registers the uploaded file with the run on self-hosted servers. Previously the file's bytes were uploaded but never committed, so the file did not appear on the run on deployments without object-store notifications (@dmitryduev in #12121)
• Sweep agents will now allow the in-progress run to complete before exiting when the sweep is deleted or Api() returns 404 (@kmikowicz-wandb in #11880)
• Fixed some deadlocks introduced in 0.25.1 (@timoffex in #12114 and #12159)
  • Reported when using PyTorch with Python < 3.14 (which uses the "fork" multiprocessing start method by default)
  • May have also happened during GC when using some wandb.Api functionality
