r or not the model should return the last key/values attentions (not used by all models). Only
            relevant if `config.is_decoder=True`.
        Example:

    ```python
    >>> from transformers import TrajectoryTransformerConfig, TrajectoryTransformerModel

    >>> # Initializing a TrajectoryTransformer CarlCochet/trajectory-transformer-halfcheetah-medium-v2 style configuration
    >>> configuration = TrajectoryTransformerConfig()

    >>> # Initializing a model (with random weights) from the CarlCochet/trajectory-transformer-halfcheetah-medium-v2 style configuration
    >>> model = TrajectoryTransformerModel(configuration)

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