az ml data

Note

This reference is part of the ml extension for the Azure CLI (version 2.15.0 or higher). The extension will automatically install the first time you run an az ml data command. Learn more about extensions.

Manage Azure ML data assets.

Azure ML data assets are references to file(s) in your storage services or public URLs along with any corresponding metadata. They are not copies of your data. You can use these data assets to access relevant data during model training and mount or download the referenced data to your compute target.

az ml data archive

Archive a data asset.

Archiving a data asset will hide it by default from list queries (az ml data list). You can still continue to reference and use an archived data asset in your workflows. You can archive either a data asset container or a specific data asset version. Archiving a data asset container will archive all versions of the data asset under that given name. You can restore an archived data asset using az ml data restore. If the entire data asset container is archived, you cannot restore individual versions of the data asset - you will need to restore the data asset container.

az ml data archive --name
                   [--label]
                   [--resource-group]
                   [--version]
                   [--workspace-name]

Examples

Archive an data asset container (archives all versions of that data asset)

az ml data archive --name my-env --resource-group my-resource-group --workspace-name my-workspace

Archive a specific data asset version

az ml data archive --name my-env --version 1 --resource-group my-resource-group --workspace-name my-workspace

Required Parameters

--name -n

Name of the data asset.

Optional Parameters

--label -l

Label of the data asset. Mutually exclusive with version.

--resource-group -g

Name of resource group. You can configure the default group using az configure --defaults group=<name>.

--version -v

Version of the data asset. Mutually exclusive with label.

--workspace-name -w

Name of the Azure ML workspace. You can configure the default workspace using az configure --defaults workspace=<name>.

Global Parameters

--debug

Increase logging verbosity to show all debug logs.

--help -h

Show this help message and exit.

--only-show-errors

Only show errors, suppressing warnings.

--output -o

Output format.

accepted values: json, jsonc, none, table, tsv, yaml, yamlc

default value: json

--query

--subscription

Name or ID of subscription. You can configure the default subscription using az account set -s NAME_OR_ID.

--verbose

az ml data create

Create a data asset in a workspace/registry. If you are using a registry, replace --workspace-name my-workspace with the --registry-name <registry-name> option.

Data assets can be defined from files on your local machine or as references to files in cloud storage. The created data asset will be tracked in the workspace/registry under the specified name and version.

To create a data asset from file(s) on your local machine, specify the 'path' field in your YAML config. Azure ML will upload these file(s) to the blob container that backs the workspace's default datastore (named 'workspaceblobstore'). The created data asset will then point to that uploaded data.

To create a data asset that references file(s) in cloud storage, specify the 'path' to the file(s) in storage in your YAML config.

You can also create a data asset directly from a storage URL or public URL. To do so, specify the URL to the 'path' field in your YAML config. If you are using a registry, replace --workspace-name my-workspace with the --registry-name <my-registry-name> option.
