Implement the QuickStart but got an error when  using BertForMaskedLM to predict a masked token
## ❓ Questions & Help

I was running the BERT example following the instruction of pytorch-transformers' docs, but when Iusing BertForMaskedLM to predict a masked token, an error occured:
"INFO:pytorch_transformers.modeling_utils:Weights from pretrained model not used in BertForMaskedLM: ['cls.seq_relationship.weight', 'cls.seq_relationship.bias']"

Any idea how to fix this? Thanks!
Hi, this is not an error, but a warning. This warning tells you that some of the weights that were in your pretrained model were not used by the model with which you loaded them. In this case, it concerns the classification layer weight/bias.<|||||>I see, thanks!
