wandb.config, a dictionary-like object.wandb.config are usually set by providing a dictionary to the config argument of wandb.init. During a sweep, however, any configuration information passed to wandb.init is instead treated as a default value, which might be over-ridden by the sweep.config.set_defaults. Code snippets for both methods appear below:entity (a user or a team) and a project.wandb sweep, as part of the sweep configuration YAML file, as environment variables, or via the wandb/settings file.wandb: WARNING Ignoring project='speech-reconstruction-baseline' passed to wandb.init when running a sweepwandb.init call includes the project argument. That's invalid, because sweep and the runs have to be in the same project. The project is set during sweep creation, e.g. bywandb.sweep(sweep_config, project="cat-detector")400 code from the W&B anaconda API, like this one:wandb: ERROR Error while calling W&B API: anaconda 400 error: {"code": 400, "message": "TypeError: bad operand type for unary -: 'NoneType'"}metric you are optimizing in your configuration YAML file is not a metric that you are logging. For example, you could be optimizing the metric f1, but logging validation_f1. Double check that you're logging the exact metric name that you've asked the sweep to optimize.wandb agent --count 1 SWEEP_ID in each of your scheduled jobs, which will run a single training job and then exit. This makes it easier to predict runtimes when requesting resources and takes advantage of the parallelism of hyperparameter search.CommError, Run does not exist?ERROR Error uploading, you might be setting an ID for your run, e.g. wandb.init(id="some-string") . This ID needs to be unique in the project, and if it's not unique, the error above will be thrown. In the sweeps context, you can't set a manual ID for your runs because we're automatically generating random, unique IDs for the runs.name instead of id. For example:command key in the YAML file, like so:${args} key expands to all the parameters in the sweep configuration file, expanded so they can be parsed by argparse: --param1 value1 --param2 value2argparse you can use:python might point to Python 2. To ensure Python 3 is invoked, just use python3 instead of python when configuring the command:nu parameter set to 1.5 -- this corresponds to much a weaker smoothness assumption than for the radial basis function (RBF) kernel. For details on kernels in Gaussian processes, see Chapter 4 of Rasmussen and Williams or the scikit-learn docs linked above.wandb agent command terminating when I pause the sweep?sweep_id to a place that any potential agent can read and a way for these agents to consume this sweep_id and start running. wandb agent. For instance, bring up an EC2 instance and then call wandb agent on it. In this case, you might use a SQS queue to broadcast sweep_id to a few EC2 instances and then have them consume the sweep_id from the queue and start running.
