I want to train the network from scratch

[JiuqingDong]

I want to train the network from scratch instead of a pre-trained model R-50.pkl. Then I annotate the weights in the config file.

However, I got an error.

File "/home/multiai3/anaconda3/envs/OWOD/lib/python3.7/site-packages/torch/nn/modules/module.py", line 1102, in _call_impl
return forward_call(*input, **kwargs)

"Predicted boxes or scores contain Inf/NaN. Training has diverged."

could you help to solve this problem or give me some suggestions?
