发现程序中一个错误 #1
Comments
我刚刚把代码下载下来,正在进行各种尝试。我还没很理解这个代码。但是试了大于0.2和小于0.2之后,我不觉得原来的代码是个错误。 |
我觉得原来的代码是对的,如果IOU>0.2,则说明该部分(该物体块)与当前的最大的物体块的重合度够高(大于0.2),于是,这个物体块不属于一个单独的新物体,故而将其filter_mask置零,也就是消除了一个多余的,无用的物体。 |
是的,你是对的,是我当时没理解对,不过这个github项目貌似有点问题,不知道你跑出来没有,我不管是用voc数据集还是自己的,训练很多轮后,预测结果都特别差,而且预测的结果貌似都一样,跟训练不训练没有区别,都是那几个框,完全跟没读过图像信息一样 |
我跑了30个epoch,感觉还可以。当然,我可能就挑了几张图片。你训练了多少个epoch呢?你测试了多少图片呢? |
我在voc数据集上训练了30epoch之后 他似乎并不能训练出想要的结果 |
我也是,一言不合就person,trust score特别低 |
确认模型应该是没问题 ,尝试换VGG16做backbone也能正常预测,但是太容易过拟合,加了BN也没用,可能还得换回原配的Backbone试试 |
I have trained for more than 50 epochs with one single image and the output box doesn't get closer to the ground truth. |
在tiny-yolov1.py脚本中,第150行代码:if iou_score >0.2:判断iou值大小这里应该是小于号,即:if iou_score < 0.2:
