Description:
 def load_events(filename, delimiter=r'\s+'):
 r"""Import time-stamp events from an annotation file. The file should consist of a single column of numeric values corresponding to the event times. This is primarily useful for processing events which lack duration, such as beats or onsets. Parameters filename : str Path to the annotation file delimiter : str Separator regular expression. By default, lines will be split by any amount of whitespace. Returns ------- event_times : np.ndarray array of event times (float) """
