ClearML Data CLI

:::important This page covers clearml-data, ClearML's file-based data management solution. See Hyper-Datasets for ClearML's advanced queryable dataset management solution. :::

clearml-data is a data management CLI tool that comes as part of the clearml python package. Use clearml-data to create, modify, and manage your datasets. You can upload your dataset to any storage service of your choice (S3 / GS / Azure / Network Storage) by setting the dataset's upload destination (see --storage). Once you have uploaded your dataset, you can access it from any machine.

The following page provides a reference to clearml-data's CLI commands.

create

Creates a new dataset.

clearml-data create [-h] [--parents [PARENTS [PARENTS ...]]] [--project PROJECT] 
                    --name NAME [--version VERSION] [--output-uri OUTPUT_URI] 
                    [--tags [TAGS [TAGS ...]]]

Parameters

Name	Description	Mandatory
--name	Dataset's name
--project	Dataset's project
--version	Dataset version. Use the semantic versioning scheme. If not specified a version will automatically be assigned
--parents	IDs of the dataset's parents. The dataset inherits all of its parents' content. Multiple parents can be entered, but they are merged in the order they were entered
--output-uri	Sets where dataset and its previews are uploaded to
--tags	Dataset user tags. The dataset can be labeled, which can be useful for organizing datasets

:::tip Dataset ID

• For datasets created with clearml v1.6 or newer on ClearML Server v1.6 or newer, find the ID in the dataset version's info panel in the Dataset UI.
  For datasets created with earlier versions of clearml, or if using an earlier version of ClearML Server, find the ID in the task header of the dataset task's info panel.
• clearml-data works in a stateful mode so once a new dataset is created, the following commands do not require the --id flag. :::

add

Add individual files or complete folders to the dataset.

clearml-data add [-h] [--id ID] [--dataset-folder DATASET_FOLDER]
                 [--files [FILES [FILES ...]]] [--wildcard [WILDCARD [WILDCARD ...]]]
                 [--links [LINKS [LINKS ...]]] [--non-recursive] [--verbose]

Parameters

Name	Description	Mandatory
--id	Dataset's ID. Default: previously created / accessed dataset
--files	Files / folders to add. Items will be uploaded to the dataset's designated storage.
--wildcard	Add specific set of files, denoted by these wildcards. For example: ~/data/*.jpg ~/data/json. Multiple wildcards can be passed.
--links	Files / folders link to add. Supports S3, GS, Azure links. Example: s3://bucket/data azure://<account name>.blob.core.windows.net/path/to/file. Items remain in their original location.
--dataset-folder	Dataset base folder to add the files to in the dataset. Default: dataset root
--non-recursive	Disable recursive scan of files
--verbose	Verbose reporting

remove

Remove files/links from the dataset.

clearml-data remove [-h] [--id ID] [--files [FILES [FILES ...]]] 
                    [--non-recursive] [--verbose]

Parameters

Name	Description	Mandatory
--id	Dataset's ID. Default: previously created / accessed dataset
--files	Files / folders to remove (wildcard selection is supported, for example: ~/data/*.jpg ~/data/json). Notice: file path is the path within the dataset, not the local path. For links, you can specify their URL (for example, s3://bucket/data)
--non-recursive	Disable recursive scan of files
--verbose	Verbose reporting

upload

Upload the local dataset changes to the server. By default, it's uploaded to the ClearML file server. You can specify a different storage medium by entering an upload destination. For example:

• A shared folder: /mnt/shared/folder
• S3: s3://bucket/folder
• Non-AWS S3-like services (such as MinIO): s3://host_addr:port/bucket
• Google Cloud Storage: gs://bucket-name/folder
• Azure Storage: azure://<account name>.blob.core.windows.net/path/to/file

clearml-data upload [-h] [--id ID] [--storage STORAGE] [--chunk-size CHUNK_SIZE] 
                    [--verbose]

Parameters

Name	Description	Mandatory
--id	Dataset's ID. Default: previously created / accessed dataset
--storage	Remote storage to use for the dataset files. Default: files_server
--chunk-size	Set dataset artifact upload chunk size in MB. Default 512, (pass -1 for a single chunk). Example: 512, dataset will be split and uploaded in 512 MB chunks.
--verbose	Verbose reporting

close

Finalize the dataset and make it ready to be consumed. This automatically uploads all files that were not previously uploaded. Once a dataset is finalized, it can no longer be modified.

clearml-data close [-h] [--id ID] [--storage STORAGE] [--disable-upload]
                   [--chunk-size CHUNK_SIZE] [--verbose]

Parameters

Name	Description	Mandatory
--id	Dataset's ID. Default: previously created / accessed dataset
--storage	Remote storage to use for the dataset files. Default: files_server
--disable-upload	Disable automatic upload when closing the dataset
--chunk-size	Set dataset artifact upload chunk size in MB. Default 512, (pass -1 for a single chunk). Example: 512, dataset will be split and uploaded in 512 MB chunks.
--verbose	Verbose reporting

sync

Sync a folder's content with ClearML. This option is useful in case a user has a single point of truth (i.e. a folder) which updates from time to time.

Once an update should be reflected in ClearML's system, call clearml-data sync and pass the folder path, and the changes (either file addition, modification and removal) will be reflected in ClearML.

This command also uploads the data and finalizes the dataset automatically.

clearml-data sync [-h] [--id ID] [--dataset-folder DATASET_FOLDER] --folder FOLDER
                  [--parents [PARENTS [PARENTS ...]]] [--project PROJECT] [--name NAME]
                  [--version VERSION] [--output-uri OUTPUT_URI] [--tags [TAGS [TAGS ...]]]
                  [--storage STORAGE] [--skip-close] [--chunk-size CHUNK_SIZE] [--verbose]

Parameters

Name	Description	Mandatory
--id	Dataset's ID. Default: previously created / accessed dataset
--dataset-folder	Dataset base folder to add the files to (default: Dataset root)
--folder	Local folder to sync. Wildcard selection is supported, for example: ~/data/*.jpg ~/data/json
--storage	Remote storage to use for the dataset files. Default: files server
--parents	IDs of the dataset's parents (i.e. merge all parents). All modifications made to the folder since the parents were synced will be reflected in the dataset
--project	If creating a new dataset, specify the dataset's project name
--name	If creating a new dataset, specify the dataset's name
--version	Specify the dataset's version using the semantic versioning scheme. Default: 1.0.0
--tags	Dataset user tags
--skip-close	Do not auto close dataset after syncing folders
--chunk-size	Set dataset artifact upload chunk size in MB. Default 512, (pass -1 for a single chunk). Example: 512, dataset will be split and uploaded in 512 MB chunks.
--verbose	Verbose reporting
