-First, the answer in stackoverflow saying that it's may caused by forgetting to change the number of classes in `test.prototxt` (same as `train.protxt`) to fit your dataset. If you've changed it but still encounterd the error, follow my renaming approach (rename layers `bbox_pred` and `cls_score`) descripted in this article to re-train your model.
