DatasetVersion

class datasetversion.DatasetVersion()​

DatasetVersion represents a specific version in a dataset.

danger

Do not instantiate directly. Use DatasetVersion.get_version method instead.

BulkContext​

class BulkContext

A context manager to modify frames (i.e. add/update/remove) in bulk.

Use DatasetVersion.get_bulk_context to obtain.

The bulk context allows modifying the version by adding/updating/deleting of frames one at a time, but the actual update request will happen in bulk. The update request (flush) will happen every flush_threshold updates, or upon __exit__.

Create Bulk context for automatically flushing frames

  • Parameters

    • dv (DatasetVersion) – DatasetVersion object to use

    • flush_threshold (Optional[int]) – If provided flush every X frames

    • log (Optional[Logger]) – Optional, provide external logger

    • refresh_version_stats (Optional[bool]) – automatically refresh version statistics (default: True)

    • auto_upload_destination (Optional[str]) – If specified any local file linked by a SingleFrame/FrameGroup, will be automatically uploaded to the destination storage.

    • local_dataset_root_path (Union[str, Path, None]) – Required if auto_upload_destination is provided. It should point to the common folder for all local source files

add_frame​

BulkContext.add_frame(frame, warn_on_duplicate_frames=False)

NOTICE! If frames already contain frame.id field, they will update (overwrite) existing frames. If not provided, frame.id is generated based on the source URI. If a local file should be uploaded but has already been previously uploaded, the existing URI for that file will be reused, otherwise the file will be uploaded.

info

Only available if version is still in draft (writable) mode

  • Parameters

    • frame (DatasetVersion.Frame ) – The frame to add to the version.

    • warn_on_duplicate_frames (Optional[bool]) – If True, issue a warning when adding a frame with an ID that was previously added to this instance (default False)

  • Return type

    None

delete_frame​

BulkContext.delete_frame(frame, delete_sources=False)

Delete a frame from the current DatasetVersion.

The frame may be represented by an ID string, or a DatasetVersion.Frame object. Frames are deleted by their IDs, all other frame attributes (if exists) are ignored.

info

Only available if version is still in draft (writable) mode.

  • Parameters

    • frame (Union[FrameGroup, SingleFrame, str, ForwardRef]) – The frame to delete (frame object or ID string)

    • delete_sources (bool) – Delete sources associated with the deleted frames in the dataset. Supported source locations are: s3, gs and azure. In case a connection cannot be established with the cloud provider or a source deletion failed, the operation will abort.

  • Return type

    None

flush​

BulkContext.flush()

Send any outstanding version changes.

Any updates made using this BulkContext are sent to the server.

  • Return type

    None

update_frame​

BulkContext.update_frame(frame)

Update an existing frame in the current DatasetVersion.

Find the frame by its ID, and change its properties to match that of the frame object passed in frame. Frames exist in a version if they were previously added (e.g. by update_frame), or if they exist in a parent version. If the frame object does not have an ID, create a new frame.

    • log (Optional[Logger]) – Logger object for the context to log to. Defaults to the datasetversion module logger.

    • refresh_version_stats (Optional[bool]) – Automatically call commit_version after deleting frames to refresh this version’s statistics.

    • auto_upload_destination (Optional[str]) – If specified any local file linked by a SingleFrame/FrameGroup, will be automatically uploaded to the destination storage. Examples: ‘s3://bucket/datasets/’, ‘gs://bucket/dataset’, ‘azure://bucket/dataset’, ‘http://clearml-server/bucket/dataset’

      Notes:

      1. The uploaded files will keep the same structure inside the designation storage under
      dataset_id/version_name.version_id/ folders
      2. If a file content hash is already registered, it will automatically link to
      the existing remote file instead of re-uploading the local copy
      3. Inside the dataset/version folder the files are stored in the same path as on the local storage,
      relative to the provided local_root_dataset_folder

    • local_dataset_root_path (Union[str, Path, None]) – Required if auto_upload_destination is provided. It should point to the common folder for all local source files, This root folder is used to detect the relative path of a single source file, to be uploaded to the remote storage. Example: 'auto_upload_destination='s3://bucket/datasets/', local_dataset_root_path='/home/user/data/' will make sure a file ‘/home/user/data/images/01/1.jpg’ will be uploaded to: ‘s3://bucket/datasets/dataset_id/version_id/images/01/1.jpg’

  • Return type

    ForwardRef

  • Returns

    A bulk update context manager for this DatasetVersion

flush​

flush(refresh_version_stats=True)

Send any outstanding version changes.

If a BulkContext was obtained by get_bulk_context, any updates made using it are sent to the server. If not, this is a no-op.

  • Parameters

    refresh_version_stats (Optional[bool]) – Automatically call commit_version to refresh this version’s statistics.

  • Return type

    None

commit_version​

commit_version(kwargs)**

Commit this draft DatasetVersion, with all the changes made so far.

Committing a version merges changes done to it with the parent version. Further changes to the version are still possible. This is a must step before publishing the version.

danger

This is a blocking method and may take time to finish.

  • Return type

    CallResult

  • Parameters

    kwargs (Any ) –

publish_version​

publish_version()

Publish this DatasetVersion.

After publishing a version it is no longer a draft version and no further changes are allowed for this version.

  • Return type

    bool

  • Returns

    True if successful, False otherwise.

get_stats​

get_stats()

Returns this version’s statistics

  • Return type

    None

get_parent​

get_parent()

Returns the ID of this version’s parent version

  • Return type

    str

get_metadata​

get_metadata()

  • Return type

    dict

  • Returns

    return metadata (dict) of user defined values stored for the specific Dataset Version

set_metadata​

set_metadata(metadata)

Store metadata (dict) of user defined values stored for the specific Dataset Version

  • Parameters

    metadata (dict ) – key/value dictionary (with support for nested dictionaries)

  • Return type

    bool

  • Returns

    True if successful (locked/published versions cannot change version metadata)

set_masks_labels​

set_masks_labels(mask_value_label_mapping)

Store a global (dataset version wide) lookup for per pixel mask values to labels. For example:

{
  (0,0,0): ["background"],
  (1,1,1): ["person", "sitting"],
  (2,2,2): ["cat"],
}

Pixel masks label lookup is stored as a property on the dataset version metadata. Specifically: dataset.get_metadata()[‘mask_labels’] = {…}

  • Parameters

    mask_value_label_mapping (dict ) – key/value dictionary. Key is a tuple of integers, and value is a list/tuple of strings

  • Return type

    bool

  • Returns

    True if successful (locked/published versions cannot change version metadata)

get_masks_labels​

get_masks_labels()

Get the global (dataset version wide) lookup for per pixel mask values to labels. For example:

{
  (0,0,0): ["background"],
  (1,1,1): ["person", "sitting"],
  (2,2,2): ["cat"],
}

Pixel masks label lookup is stored as a property on the dataset version metadata. Specifically: dataset.get_metadata()[‘mask_labels’] = {…}

  • Return type

    Dict[tuple, tuple]

  • Returns

    key/value dictionary. key is a tuple of integers, and value is a list/tuple of strings
