got fvcore.common.checkpoint WARNING

[wmrenr]

Thanks for your great contribution！
Except for changing the dataset, everything else is in accordance with the repo guidance，but I get this warning when training with my own coco format dataset：fvcore.common.checkpoint WARNING: Some model parameters or buffers are not found in the checkpoint:
�[34mbackbone.fpn_lateral2.{bias, weight}�[0m
�[34mbackbone.fpn_lateral3.{bias, weight}�[0m

......
what caused this？

The initial backbone weight Resnet 50 or 101 does not have these parameters.

Oh,how to avoid this problem?

It's just a warning. You can ignore it.
