open3d.ml.torch.datasets.Custom3D

class open3d.ml.torch.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 dataset that 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

• 'training' –

• 'test' –

• 'validation' –

• 'all'. (or) –

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

• 'training' –

• 'test' –

• 'validation' –

• 'all'. (or) –

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 if a datum in the dataset has been tested.

Parameters

• dataset – The current dataset to which the datum belongs to.

• attr – The attribute that needs to be checked.

Returns

If the dataum attribute is tested, then resturn the path where the attribute is stored; 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.
