Mounting Storage Volumes

Beam allows you to create highly-available storage volumes that can be used across tasks. You might use volumes for things like storing model weights or large datasets.

​

Mounting a Volume

Volumes can be attached to an App. By default, Volumes are shared across all apps in your Beam account.

from beam import function, Volume


VOLUME_PATH = "./model_weights"


@function(
    volumes=[Volume(name="model-weights", mount_path=VOLUME_PATH)],
)
def load_model():
    from transformers import AutoModel

    # Load model from cloud storage cache
    AutoModel.from_pretrained(VOLUME_PATH)

​

Browsing Volume Contents

You can list all your volumes through the web dashboard, or CLI using the beam volume list command.

You can also browse all contents of a volume with the beam volume ls command:

​

Deleting Volumes

You can delete a volume in the web dashboard. Click the three-dots icon next to a volume, and click Delete Volume to permanently delete it.
