            Attention used in encoder. This can be set to "prob" (Informer's ProbAttention) or "full" (vanilla
            transformer's canonical self-attention).
        sampling_factor (`int`, *optional*, defaults to 5):
            ProbSparse sampling factor (only makes affect when `attention_type`="prob"). It is used to control the

            Whether to use distilling in encoder.

    Example:

    ```python
    >>> from transformers import InformerConfig, InformerModel

    >>> # Initializing an Informer configuration with 12 time steps for prediction
    >>> configuration = InformerConfig(prediction_length=12)

    >>> # Randomly initializing a model (with random weights) from the configuration
    >>> model = InformerModel(configuration)

    >>> # Accessing the model configuration
    >>> configuration = model.config
