and in the visdom I cannot see any loss with cls or loc

hello，how do you solve it? I met it too

same!Help! This Only happens when using caffe pre-trained

I was able to mitigate this issue by using the Adam optimizer (setting the use_adam bool in config to True).

I hope this helps.

It works! Thanks. This is a rather wired problem, I couldn't figure out why the bbox_tools is affected by optimizers.

Updates. I changed the optimizer to Adam according to jaypmorgan's suggestion. The training and loss curves seem normal now, however, I am still encountering these warnings, even though my training process is not influenced by these warnings...
