Embedding index out of range in self
# 🐛 Bug

## Information

Model I am using (Bert, XLNet ...): Bert cased (size=768)

Language I am using the model on (English, Chinese ...): English

The problem arises when using:
* [ ] the official example scripts: (give details below) 
* [ ] my own modified scripts: (give details below) When I feed the ids converted by BERTtokenizer to BERT embedding layer, it shows that the dimension does not match.

The tasks I am working on is:
* [ ] an official GLUE/SQUaD task: (give the name)
* [ ] my own task or dataset: (give details below) task: text binary classification. dataset: ICLR2020 peer reviews

## To reproduce

Steps to reproduce the behavior:

1. use BERT model and BERT tokenizer
2. convert the text of any datasets to ids
3. feed to the BERT model

## Expected behavior

The dimension should match. Actually, the code works two days ago. I did not change anything and today it does not work.

The error is: return torch.embedding(weight, input, padding_idx, scale_grad_by_freq, sparse) and index out of range in self.

Sorry, I think it is due to a bug in my code. Please close it.<|||||>@zht1130 Were you able to identify the bug? I'm seeing a similar error.<|||||>> @zht1130 Were you able to identify the bug? I'm seeing a similar error.

1. Run the model on the CPU instead of GPU will give you more detailed information.
2. BERT layer only receives token ids whose length smaller than 512.
