Exceptions

Description

Exceptions classes for handling error and displaying messages.

Classes

class krajjat.classes.exceptions.InvalidPathException(path, object_type, reason)

Exception raised when a path provided does not point towards a valid Sequence or Audio. This error can be raised:

  • When multiple file extensions compatible with the toolbox are detected in the same folder.

  • When files are named sequentially (e.g. pose_1.txt, pose_2.txt, etc.), and at least one file of the sequence is missing.

  • When a provided file has an incompatible extension.

  • When the folder or file does not exist.

New in version 2.0.

Parameters:

  • path (str) – The path to a file or folder.

  • object_type (str) – The type of the element the path is supposed to point towards ("sequence" or "audio clip").

  • reason (str) – A short description of the reason the path is invalid.

class krajjat.classes.exceptions.InvalidParameterValueException(name, given_value, expected_values=None)

Exception raised when the value of a parameter is not one of the expected ones.

New in version 2.0.

Parameters:

  • name (str) – The name of the parameter set at an invalid value.

  • given_value – The invalid value given to the parameter.

  • expected_values (list, optional) – The expected value or values the parameter should have.

class krajjat.classes.exceptions.EmptyInstanceException(kind)

Exception raised when the instance of a Sequence, Audio or AudioDerivative does not have any pose.

New in version 2.0.

class krajjat.classes.exceptions.ImpossibleTimeTravelException(index1, index2, timestamp1, timestamp2, number_of_timestamps, object_type)

Exception raised if two consecutive timestamps are not in chronological order.

New in version 2.0.

Parameters:

  • index1 (int) – The index of a first pose or sample.

  • index2 (int) – The index of a second pose or sample, higher than the first.

  • timestamp1 (float) – The timestamp of the first pose or sample.

  • timestamp2 (float) – The timestamp of the second pose or sample.

  • number_of_timestamps (int) – The number of timestamps in the original object.

  • object_type (str) – The type of the element the path is supposed to point towards ("sequence" or "audio clip").

class krajjat.classes.exceptions.InvalidJointLabelException(joint_label)

Exception raised when the provided joint name does not exist in the Sequence or the Pose.

New in version 2.0.

Parameters:

joint_label (str) – The label of the joint (e.g. "Head").

class krajjat.classes.exceptions.ModuleNotFoundException(module_name, attempted_task)

Exception raised when a specific Python module has not been found installed in the execution environment.

New in version 2.0.

Parameters:

  • module_name (str) – The name of the Python module that failed to load.

  • attempted_task (str) – A short description of the reason the module was necessary.

class krajjat.classes.exceptions.InvalidPoseIndexException(pose_index, number_of_poses)

Exception raised when a pose index provided does not exist in the Sequence instance.

New in version 2.0.

Parameters:

  • pose_index (int) – The invalid index of the pose that was provided.

  • number_of_poses (int) – The number of poses in the Sequence instance.

class krajjat.classes.exceptions.JointLabelAlreadyExistsException(joint_label)

Exception raised when tying to add a joint with a label that already exists in a Pose object.

New in version 2.0.

Parameters:

joint_label (str) – The joint label that already exists in the Pose object.

class krajjat.classes.exceptions.PoseAlreadyExistsException(sequence_name, timestamp)

Exception raised when tying to add a pose with a timestamp that already exists in a Sequence object.

New in version 2.0.

Parameters:

  • sequence_name (str) – The name of the target Sequence object.

  • timestamp (float) – The timestamp of the pose that already exists in the Sequence object.

class krajjat.classes.exceptions.NotASubPathException(path1, path2)

Exception raised when a path is not a parent of another.

New in version 2.0.

Parameters:

  • path1 (str) – The alleged parent path

  • path2 (str) – The alleged child path

class krajjat.classes.exceptions.DifferentSequencesLengthsException(sequence1, sequence2)

Exception raised when two sequences have a different number of poses.

New in version 2.0.

Parameters:

  • sequence1 (Sequence) – A Sequence instance.

  • sequence2 (Sequence) – Another Sequence instance

class krajjat.classes.exceptions.MissingRecordingDateException(sequence)

Exception raised when a Sequence is missing a recording date.

New in version 2.0.

Parameters:

sequence (Sequence) – A Sequence instance.

class krajjat.classes.exceptions.NoExistingJointListPresetException(variable_name, system)

Exception raised when no existing joint list preset is found for a certain system.

New in version 2.0.

Parameters:

  • variable_name (str) – The name of the variable to calculate.

  • system (str) – The recording system of the Sequence instance.

class krajjat.classes.exceptions.VariableSamplingRateException(sequence_name)

Exception raised when performing an operation that does not support a variable sampling rate.

New in version 2.0.

Parameters:

sequence_name (str) – The name of the sequence.
