modeling_openai.py bug report
line 651 has a potential bug

```        # Copy word and positional embeddings from the previous weights
        self.tokens_embed.weight.data[: self.config.vocab_size, :] = old_embed.weight.data[: self.config.vocab_size, :]
        self.tokens_embed.weight.data[-self.config.n_positions :, :] = old_embed.weight.data[-self.config.n_positions :, :]
```
isn't it supposed to be `self.positions_embed ` instead of `self.tokens_embed` ?
Good catch, I'll fix this.
