After upgrading to pytorch 0.4.0 I get warning about my old saved models, how to fix it?

Should I worry about this error?

.../envs/pytorch_4/lib/python3.6/site-packages/torch/serialization.py:367: SourceChangeWarning: source code of class 'torch.nn.modules.conv.Conv2d' has changed. you can retrieve the original source code by accessing the object's source attribute or set `torch.nn.Module.dump_patches = True` and use the patch tool to revert the changes.
  warnings.warn(msg, SourceChangeWarning)

Can I fix this?

Have you solved it? I also encountered the same problem
