v0.20.0

@domphan-wandb

What's Changed

wandb.Table: Added new constructor param, log_mode, with options "IMMUTABLE" and "MUTABLE". IMMUTABLE log mode (default) is existing behavior that only allows a table to be logged once. MUTABLE log mode allows the table to be logged again if it has been mutated. (@domphan-wandb in #9758)
wandb.Table: Added a new log_mode, "INCREMENTAL", which logs newly added table data incrementally. (@domphan-wandb in #9810)

This version removes the ability to disable the service process. This is a breaking change.

Added merge parameter to Artifact.add_dir to allow overwrite of previously-added artifact files (@pingleiwandb in #9907)
Support for pytorch.tensor for masks and boxes parameters when creating a wandb.Image object. (@jacobromero in #9802)
sync_tensorboard now supports syncing tfevents files stored in S3, GCS and Azure (@timoffex in #9849)
- GCS paths use the format gs://bucket/path/to/log/dir and rely on application-default credentials, which can be configured using gcloud auth application-default login
- S3 paths use the format s3://bucket/path/to/log/dir and rely on the default credentials set through aws configure
- Azure paths use the format az://account/container/path/to/log/dir and the az login credentials, but also require the AZURE_STORAGE_ACCOUNT and AZURE_STORAGE_KEY environment variables to be set. Some other environment variables are supported as well, see here.
Added support for initializing some Media objects with pathlib.Path (@jacobromero in #9692)
New setting x_skip_transaction_log that allows to skip the transaction log. Note: Should be used with caution, as it removes the gurantees about recoverability. (@kptkin in #9064)
normalize parameter to wandb.Image initialization to normalize pixel values for Images initialized with a numpy array or pytorch tensor. (@jacobromero in #9883)

Various APIs now raise TypeError instead of ValueError or other generic errors when given an argument of the wrong type. (@timoffex in #9902)
Various Artifacts and Automations APIs now raise CommError instead of ValueError upon encountering server errors, so as to surface the server error message. (@ibindlish in #9933)
wandb.sdk.wandb_run.Run::save method now requires the glob_str argument (@dmitryduev in #9962)

Removed support for disabling the service process. The x_disable_service/_disable_service setting and the WANDB_DISABLE_SERVICE/WANDB_X_DISABLE_SERVICE environment variable have been deprecated and will now raise an error if used (@kptkin in #9829)
Removed ability to use wandb.docker after only importing wandb (@timoffex in #9941)
- wandb.docker is not part of wandb's public interface and is subject to breaking changes. Please do not use it.
Removed no-op sync argument from wandb.Run::log function (@kptkin in #9940)
Removed deprecated wandb.sdk.wandb_run.Run.mode property (@dmitryduev in #9958)
Removed deprecated wandb.sdk.wandb_run.Run::join method (@dmitryduev in #9960)

The start_method setting is deprecated and has no effect; it is safely ignored (@kptkin in #9837)
The property Artifact.use_as and parameter use_as for run.use_artifact() are deprecated since these have not been in use for W&B Launch (@ibindlish in #9760)

Calling wandb.teardown() in a child of a process that called wandb.setup() no longer raises WandbServiceNotOwnedError (@timoffex in #9875)
- This error could have manifested when using W&B Sweeps
Offline runs with requested branching (fork or rewind) sync correctly (@dmitryduev in #9876)
Log exception as string when raising exception in Job wait_until_running method (@KyleGoyette in #9607)
wandb.Image initialized with tensorflow data would be normalized differently than when initialized with a numpy array (@jacobromero in #9883)
Using wandb login no longer prints a warning about wandb.require("legacy-service") (@timoffex in #9912)
Logging a Table (or other objects that create internal artifacts) no longer raises ValueError when logged from a run whose ID contains special characters. (@tonyyli-wandb in #9943)
wandb.Api initialized with the base_url now respects the provided url, rather than the last login url (@jacobromero in #9942)
