This class is used to create a dataset based on the SemanticKitti dataset, and used in visualizer, training, or testing.
The dataset is best for semantic scene understanding.

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 (Semantic3D in this case).
cache_dir – The directory where the cache is stored.
use_cache – Indicates if the dataset should be cached.
class_weights – The class weights to use in 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.
- Returns:
The corresponding class.
- Return type:
class
- static get_label_to_names()#
Returns a label to names dictionary 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:
attr – The attribute that needs to be checked.
- Returns:
- If the datum attribute is tested, then return 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.
- save_test_result_kpconv(results, inputs)#
