Problem of angle prediction

[Fly-dream12]

Thanks for you r code.
I have trained this model on my dataset, but when i predict the targets, the angle prediction turns to be zero.
Furthermore, the loss did not converge when epoch=100.
Please give some suggestions.

I'm very sorry to hear from you so late.
I guess there's something wrong with your label, and i have pushed the labelGenerator to here:
https://github.com/ZeroE04/R-CenterNet/tree/master/labelGenerator

you can have a look, good luck for you!

Sorry, I have made the label as you suggested as retrained it, but the results are still with horizontal results. And the angle prediction is still zero.

@Fly-dream12 I also meet the same problem. I counted the angles of all my samples as below(ps:I changed the angle interval to (-180,180)):

Could it be caused by the unbalanced angular frequency of the sample? @ZeroE04
