      The default image size used to train this network is 224x224.
  
      Args:
        inputs: a tensor of size [batch_size, height, width, channels].
        num_classes: number of predicted classes. If 0 or None, the logits layer
          is omitted and the input features to the logits layer (before dropout)
          are returned instead.
        is_training: whether is training or not.
        dropout_keep_prob: the percentage of activation values that are retained.
        prediction_fn: a function to get predictions out of logits.
        spatial_squeeze: if True, logits is of shape [B, C], if false logits is of
            shape [B, 1, 1, C], where B is batch_size and C is number of classes.
        reuse: whether or not the network and its variables should be reused. To be
          able to reuse 'scope' must be given.
        scope: Optional variable_scope.
        global_pool: Optional boolean flag to control the avgpooling before the
          logits layer. If false or unset, pooling is done with a fixed window
          that reduces default-sized inputs to 1x1, while larger inputs lead to
          larger outputs. If true, any input size is pooled down to 1x1.
  
      Returns:
        net: a Tensor with the logits (pre-softmax activations) if num_classes
          is a non-zero integer, or the non-dropped-out input to the logits layer
          if num_classes is 0 or None.
        end_points: a dictionary from components of the network to the corresponding
          activation.
