我也是一样的,训练自己的数据,从数据来看,训练效果比yolov3好,但是保存了权重后去做测试,什么都检测不出来,关键是模型输出的是个空列表什么都没有。这是这么回事啊。

我也遇到这个问题,训练loss已经降到很低了。但不论用训练过程中的任意一个权重文件都无法检测出框。检查时发现在yolo.py的out_boxes, out_scores, out_classes = self.sess.run(xxx)位置,run出来的out_boxes, out_scores, out_classes均为3个空列表,于是调低了score的阈值,发现能输出框了,但所有框的置信度均为0.000。推测原因1.可能是train与pred过程中对图片的预处理不一致?2.我分类数只有1类导致分类loss比重很小坐标偏差比重很大?正在排查。

换过其他数据集,也是一样的情况,实在是不只道为什么

这特征这么少,不好拟合吧

有朋友解决这个问题了吗,训练的loss值已经收敛了,但一直都是0bbox,包括用训练集的图片也是如此
