class tensorbay.label.label.Label

Bases: tensorbay.utility.repr.ReprMixin, tensorbay.utility.attr.AttrsMixin

This class defines label.

It contains growing types of labels referring to different tasks.

Examples

>>> from tensorbay.label import Classification
>>> label = Label()
>>> label.classification = Classification("example_category", {"example_attribute1": "a"})
>>> label
Label(
  (classification): Classification(
    (category): 'example_category',
    (attributes): {...}
  )
)

classmethod loads(contents: Dict[str, Any]) → tensorbay.label.label._T

Loads data from a dict containing the labels information.

Parameters

Returns

A Label instance containing labels information from the given dict.

Examples

>>> contents = {
...     "CLASSIFICATION": {
...         "category": "example_category",
...         "attributes": {"example_attribute1": "a"}
...     }
... }
>>> Label.loads(contents)
Label(
  (classification): Classification(
    (category): 'example_category',
    (attributes): {...}
  )
)

dumps() → Dict[str, Any]

Returns

Dumped labels dict.

Examples

>>> from tensorbay.label import Classification
>>> label = Label()
