=== Béluga === | |||
While it is possible to upload basic metrics to Weights&Biases during a job on Béluga, the wandb package automatically uploads information about the user's environment to a Google Cloud Storage bucket. It is not currently possible to disable this behaviour. Uploading artifacts to W&B with <tt>wandb.save()</tt> also requires access to Google Cloud Storage, which is not available on Béluga's compute nodes. | |||
Users can still use wandb on Béluga by enabling the [https://docs.wandb.ai/library/cli#wandb-offline <tt>offline</tt>] or [https://docs.wandb.ai/library/init#save-logs-offline <tt>dryrun</tt>] modes. In these two modes, wandb will write all metrics, logs and artifacts to the local disk and will not attempt to sync anything to the Weights&Biases service on the internet. After their jobs finish running, users can sync their wandb content to the online service by running the command [https://docs.wandb.ai/ref/cli#wandb-sync <tt>wandb sync</tt>] on the login node. | |||

L'exemple suivant montre comment utiliser wandb pour le suivi de l'expérimentation sur Béluga. Pour reproduire ceci sur Cedar, il n'est pas nécessaire de charger le module <tt>httpproxy</tt>. | L'exemple suivant montre comment utiliser wandb pour le suivi de l'expérimentation sur Béluga.
