class_docstr: A manager class to manipulate the tensors in chunks.
  
  Args:
      chunk_configuration (Dict[int, Dict]): the configuration dictionary of this chunk manager.
      init_device (torch.device): optional, the device on which the chunk is initialized. The default is None.
docstr: Close all the chunks of all groups.
