at first steps,loss is 0.35 and always 0.35,0.34 in 70000steps, why????

henbucuoshanghai commented 5 years ago

lr is too big??

sunjinbing commented 5 years ago

loss_cls: 0.003523 loss_box: 0.000122 is small enough or overfitting

henbucuoshanghai commented 5 years ago

but at first 20 steps，the loss is 0.35 too, it does not change ............................

henbucuoshanghai commented 5 years ago

small enough .... ok try bigger..

zxz-cc commented 4 years ago

I have the same problem ,and the loss_cls and loss_box are the 0 .why??

zxz-cc commented 4 years ago

Is there anyone can tell me the reason why the loss_cls and loss_box are zero all the time when i trained???
