The problem of eval speed

[LDoubleZhi]

I write a img_detect func which detect per img, so I have not use dataloader. The other code is same to yours. when I test on 1080ti, I get only 0.05s/per img.Is the problem is whether using dataloader?

speed.py do not do any postprocess, maybe it's the difference.

把conf_threshold设置为0.2以上，速度就上来了，因为conf_threshold越低mAP越高，但是速度越慢（需要NMS大量的bbox）

对的，还有就是后处理的锅了（笑哭）

楼主可以把你的检测代码分享给我么，我的邮箱是1425751338@qq.com，我这边写了一个可以画pr曲线输出mAP的代码，如果你有需要，我也可以发给你，不甚感谢。

@qhykwsw @Stinky-Tofu Could you kindly share your code for calculating mAP?
