    Parameters
    ----------
    model_file : Path
        The name of the frozen model file.
    load_prefix: str
        The prefix in the load computational graph
    default_tf_graph : bool
        If uses the default tf graph, otherwise build a new tf graph for evaluation

    Warnings
    --------
    For developers: `DeepTensor` initializer must be called at the end after
    `self.tensors` are modified because it uses the data in `self.tensors` dict.
    Do not chanage the order!
