with_extra_blocks 设置为true是没问题的

Trace如下：

Traceback (most recent call last): File "tools/train.py", line 340, in main() File "tools/train.py", line 128, in main train_fetches = model.train(feed_vars) File "$paddlepaddle/work/PaddleDetection/ppdet/modeling/architectures/ssd.py", line 94, in train return self.build(feed_vars, 'train') File "$paddlepaddle/work/PaddleDetection/ppdet/modeling/architectures/ssd.py", line 82, in build inputs=body_feats, image=im, num_classes=self.num_classes) File "$paddlepaddle/work/PaddleDetection/ppdet/core/workspace.py", line 113, in partial_apply return op(*args, **kwargs_) File "/usr/local/lib/python3.5/dist-packages/paddle/fluid/layers/detection.py", line 2154, in multi_box_head 'aspect_ratios should be list or tuple, and the length of inputs ' File "/usr/local/lib/python3.5/dist-packages/paddle/fluid/layers/detection.py", line 2131, in _is_list_or_tuple_and_equal raise ValueError(err_info) ValueError: aspect_ratios should be list or tuple, and the length of inputs and aspect_ratios should be the same.

另外请教下，这里extra block是啥意思，有论文之类的原理介绍吗？ 感谢
