大神你好!
我也在用Yolo V3来做一个class的物体识别。我的项目是在一个页面里面找手写的签名。我看了一下我们的数据应该比较相似。

但我有个问题不知道能不能麻烦您解答一下:我的数据差不多是10000张图片,现在训练了6000步 (GPU),avg loss什么的也都是0.3左右比较稳定了。它的输出在这里:
Region 82 Avg IOU: 0.851243, Class: 0.999658, Obj: 0.751877, No Obj: 0.003065, .5R: 1.000000, .75R: 1.000000, count: 1
Region 94 Avg IOU: 0.922397, Class: 0.999154, Obj: 0.857456, No Obj: 0.000260, .5R: 1.000000, .75R: 1.000000, count: 1
Region 106 Avg IOU: -nan, Class: -nan, Obj: -nan, No Obj: 0.000000, .5R: -nan, .75R: -nan, count: 0
6239: 0.343649, 0.314431 avg, 0.000100 rate, 30.336593 seconds, 399296 images Loaded: 0.000050 seconds

我的Yolo模型配置是按照这里改的:https://www.cnblogs.com/codefish/p/10104320.html, 只不过测试的时候就是用YOLO自带的测试工具:
./darknet detector test cfg/signature.data cfg/yolov3-signature.data.cfg yolov3-signature.data.weights data/test.png

但是我用Yolo V3标配的test来测试的时候总是检测不到任何物体,predictions.png那个文件就是我上面的test.png,并没有识别出任何物体,不知道您有没有遇到过类似的问题?谢谢!
