    Optionally loads weights pre-trained on ImageNet.
    Note that the data format convention used by the model is
    the one specified in the `tf.keras.backend.image_data_format()`.
    Note: each Keras Application expects a specific kind of input preprocessing.
    For InceptionV3, call `tf.keras.applications.inception_v3.preprocess_input`
    on your inputs before passing them to the model.
    Arguments:
      include_top: Boolean, whether to include the fully-connected
        layer at the top, as the last layer of the network. Default to `True`.
      weights: One of `None` (random initialization),
        `imagenet` (pre-training on ImageNet),
        or the path to the weights file to be loaded. Default to `imagenet`.
      input_tensor: Optional Keras tensor (i.e. output of `layers.Input()`)
        to use as image input for the model. `input_tensor` is useful for sharing
        inputs between multiple different networks. Default to None.
      input_shape: Optional shape tuple, only to be specified
        if `include_top` is False (otherwise the input shape
        has to be `(299, 299, 3)` (with `channels_last` data format)
        or `(3, 299, 299)` (with `channels_first` data format).
        It should have exactly 3 inputs channels,
        and width and height should be no smaller than 75.
        E.g. `(150, 150, 3)` would be one valid value.
        `input_shape` will be ignored if the `input_tensor` is provided.
      pooling: Optional pooling mode for feature extraction
        when `include_top` is `False`.
        - `None` (default) means that the output of the model will be
            the 4D tensor output of the last convolutional block.
        - `avg` means that global average pooling
            will be applied to the output of the
            last convolutional block, and thus
            the output of the model will be a 2D tensor.
        - `max` means that global max pooling will be applied.
      classes: optional number of classes to classify images
        into, only to be specified if `include_top` is True, and
        if no `weights` argument is specified. Default to 1000.
      classifier_activation: A `str` or callable. The activation function to use
        on the "top" layer. Ignored unless `include_top=True`. Set
        `classifier_activation=None` to return the logits of the "top" layer.
    Returns:
      A `keras.Model` instance.
    Raises:
      ValueError: in case of invalid argument for `weights`,
        or invalid input shape.
      ValueError: if `classifier_activation` is not `softmax` or `None` when
        using a pretrained top layer.
