why dose the loss of photo_detail_mrf is nan?

[kingo233]

Hi! thank you for your excellent work.
I have finished pretrain and corase shape train,and the model's ablibity to extract pose,light,tex is good.
But when I started trainning detail,I got photo_detail_mrf is nan .
How can I solve it?

@kingo233 Hello, I'm also trying to reproduce the training process. However, after the coarse training, I couldn't get the right code['light'] while the other latent codes are well learned, I wonder can you give me some suggestions?

@zydmu123 Hi! Please give me more infomation about this problem.Can you show me your training image ?

@kingo233 Thanks, I have fixed the light, just by switching the below codes:
# ops = self.render(verts, trans_verts, albedo, codedict['light']) ops = self.render(verts, trans_verts, albedo, h=h, w=w, background=background)
and my coarse training results for now are as follows：

However, a similar problem as yours seems to arise during my detail training...

@zydmu123 Hi! I haven't solved this problem. Can you give your contact infomation? Want to communicate with you more directly

@kingo233 @zydmu123 Hello, I train coarse well. But detail result very bad. Have you trained detail well? My wechat: xuduo1029

我也遇到这个问题了，能问下你是怎么解决的吗？还有，文中说在训练细节模型时，粗模型是固定的，这代表我要将训练粗模型时的loss都置为0吗？还是需要什么别的操作啊。如能回复，感激不尽

这代表你的训练配置文件要把is_detail设置为true，训练时代码会走到另外一个分支，粗模型部分不会得到更新

原来如此，感谢感谢，我已经设置cfg.train.train_detail = true。
但是另一个我跟你之前存在的问题一样，detail阶段的 photo_detail_mrf 值为 nan，这个你是怎么解决的呢？

这个我也一直没解决，抱歉

好吧，谢谢了:>
