    Standard video model.
    The model is divided into the backbone and the head, where the backbone
    extracts features and the head performs classification.

    The backbones can be defined in model/base/backbone.py or anywhere else
    as long as the backbone is registered by the BACKBONE_REGISTRY.
    The heads can be defined in model/module_zoo/heads/ or anywhere else
    as long as the head is registered by the HEAD_REGISTRY.

    The registries automatically finds the registered modules and construct
    the base video model.
