gt_argmax_overlaps = overlaps.argmax(axis=0) ValueError: attempt to get argmax of an empty sequence错误处理

在faster rcnn内进行随机裁剪数据增强，训练一段时间后报错：

gt_argmax_overlaps = overlaps.argmax(axis=0) ValueError: attempt to get argmax of an empty sequence

参考博客http://blog.csdn.net/jiajunlee/article/details/50470897知原因是裁剪的图像或目标宽高比太小导致，更改裁剪策略可
