## ❓ How to do change the Cross Entropy using DETR to Quality focal Loss
I'm trying to use Quality focal loss with DETR but it seems that instead of anchors DETR have query embeeds, is it possible …

您好，我在阅读您的代码时，遇到了下面的问题：
```
def trans_mvsnet_loss(inputs, depth_gt_ms, mask_ms, **kwargs):
depth_loss_weights = kwargs.get("dlossw", None)
total_loss = torch.tensor(0.0, dtype=torch.float32…

# 1.将模型存储
model.save('my_model.h5')
# 2.加载模型报错
from nets.centernet_training import focal_loss, reg_l1_loss
from keras.models import load_model
model = load_model('my_model.h5', compile=False, cus…

the following code has some wrong. 'if bbox_annotation.shape[0] == 0:' if the bbox_annotation.shape[0] is zero.that is no label. so we do not computer. we need continue.

您好，我在训练FM模型，想用focal loss函数，但在配置文档中没有找到loss的配置

Hi yhenon, thanks for your open source codes of retiannet. In my experiments, the result is much better than https://github.com/fizyr/keras-retinanet. I sincerely hope that you can implement the other…

你好, 感谢你的实现,有些细节处想和你请教下:
官方版本的label是只把center这一个点当作true, 剩下的都是负样本来计算focal_loss, focal_loss里面会找哪些位置的点的值是1, 但由于是在center附近打的一个高斯核, center处并不一定能保证是1? 或者说由于打得是个高斯核, center处有可能无限趋近于1但不是1, 在focal_loss里会去寻…

### What is the feature?
I want to know what is the difference between the following two cases when using the Multiple Losses?
