这个loss正常吗： ``` [2020-10-30 07:43:01,600]-[train2.py line:157]:Epoch:[13/200] [2020-10-30 07:43:03,312]-[train2.py line:224]:Epoch:[ 13/200], step:[ 0/3344], img_size:[512], total_loss:9.8996| loss_ciou:4.6078| loss_conf:2.1304| loss_cls:3.1615| lr:0.0005 [2020-10-30 07:57:32,060]-[train2.py line:224]:Epoch:[ 13/200], step:[500/3344], img_size:[512], total_loss:8.3806| loss_ciou:3.8154| loss_conf:2.3640| loss_cls:2.2011| lr:0.0006 [2020-10-30 08:11:56,913]-[train2.py...

这个版本的实现有很多没有优化的地方，比如batch evaluation, nms用的是手撸numpy版本，我自己fork了一个实现了多级多卡训练，同时支持nms GPU速度快很多，darknet53跑起来也不卡顿了

@cangwang 等我把eval完善一下会public

this is currently a blocking issue ... can't found any solution on this for now. tried replace fonts, reinstall fonts, merge fonts.. all don't really work well.

I fixed it, but can not show any icons or svg pictures: 

@pchampio Yeah, you are right, not hover issue. But I don't know why packaged msi can not show svgs or icons. But generate flutter_app.exe can show normally.

I am just did some experiments, what's your mean by anchor size is 0.64? How's that value out and in pixel? Or according to featuremap size? I am indeed don't...

@zylo117 thanks for your clarification. so does 0.64 cover minimal pixel size 8 pixel target on my image? By how? From experiments shows, the tiny objects even with pixel >...

ok, let me try 0.25

No, I tried your tool and dedicatedly design my anchor, result also not full satisfying although it seems work but have a lots of missdetections.
