open3d.ml.tf.datasets.Custom3D

class open3d.ml.tf.datasets.Custom3D(dataset_path, name='Custom3D', cache_dir='./logs/cache', use_cache=False, num_points=65536, ignored_label_inds=[], test_result_folder='./test', **kwargs)

A template for customized datasetthat you can use with a dataloader to feed data when training a model. This inherits all functions from the base dataset and can be modified by users. Initialize the function by passing the dataset and other details.

Parameters
  • dataset_path – The path to the dataset to use.

  • name – The name of the dataset.

  • cache_dir – The directory where the cache is stored.

  • use_cache – Indicates if the dataset should be cached.

  • num_points – The maximum number of points to use when splitting the dataset.

  • ignored_label_inds – A list of labels that should be ignored in the dataset.

  • test_result_folder – The folder where the test results should be stored.

__init__(dataset_path, name='Custom3D', cache_dir='./logs/cache', use_cache=False, num_points=65536, ignored_label_inds=[], test_result_folder='./test', **kwargs)

” Initialize the class by passing the dataset path.

static get_label_to_names()

Returns a label to names dictonary object.

Returns

A dict where keys are label numbers and values are the corresponding names.

get_split(split)

Returns a dataset split.

Parameters
  • split – A string identifying the dataset split that is usually one of

  • 'test', 'validation', or 'all'. ('training',) –

Returns

A dataset split object providing the requested subset of the data.

get_split_list(split)

Returns a dataset split.

Parameters
  • split – A string identifying the dataset split that is usually one of

  • 'test', 'validation', or 'all'. ('training',) –

Returns

A dataset split object providing the requested subset of the data.

Raises:

ValueError: Indicates that the split name passed is incorrect. The split name should be one of

’training’, ‘test’, ‘validation’, or ‘all’.

is_tested(attr)

Checks whether a datum has been tested.

Parameters

attr – The attributes associated with the datum.

Returns

This returns True if the test result has been stored for the datum with the specified attribute; else returns False.

save_test_result(results, attr)

Saves the output of a model.

Parameters
  • results – The output of a model for the datum associated with the attribute passed.

  • attr – The attributes that correspond to the outputs passed in results.
