…ne process (#9746) DUPLICATED FROM PR #9562 which I accidentally merged into the wrong branch. * WB-23108, WB-24208 * Docs: wandb/docs#1145 Adds a `create_new` option to the `reinit` setting which causes `wandb.init()` to create a new run even if other runs exist. This should eventually become the default, and the other options ("return_previous" and "finish_previous") should be deprecated. Although it's possible to pass `reinit` as a `wandb.init()` argument, the best way to use this is with `wandb.setup()`. Here is an example that uses the `create_new` setting to (serially) run multiple sub-experiments while logging their results to another run: ```python wandb.setup(wandb.Settings(reinit="create_new")) with wandb.init() as experiment_results_run: for ...: with wandb.init() as run: # The do_experiment() function logs fine-grained metrics # to the given run and then returns result metrics that # we'd like to track separately. experiment_results = do_experiment(run) # After each experiment, we log its results to a parent # run. Each point in the parent run's charts corresponds # to one experiment's results. experiment_results_run.log(experiment_results) ``` --- This PR also removes `util._is_offline()` and replaces it with a heuristic that uses the newly added `most_recent_active_run`. This way, `_is_offline` continues to work as expected in most cases.

Updates documentation for wandb/wandb#9562.
NOTE: This original example on this page was wrong:
reinitwas not necessary because the example already calledrun.finish(). Settingreinit=Truesimply callsrun.finish()automatically for the user. I removed mention ofreinit=Trueas we would like to deprecate this setting completely.
