 The [modeling_olmo2.py](https://github.com/huggingface/transformers/blob/main/src/transformers/models/olmo2/modeling_olmo2.py) generated by the linter also contains some classes (`Olmo2MLP`, `Olmo2RotaryEmbedding`, `Olmo2PreTrainedModel`) that weren't explicitly defined in `modular_olmo2.py`.
 
-Classes that are a dependency of an inherited class but aren't explicitly defined are automatically added as a part of depdendency tracing. This is similar to how some functions were added to the `Attention` class without drrectly importing them.

 For example, `OlmoDecoderLayer` has an attribute defined as `self.mlp = OlmoMLP(config)`. This class was never explicitly redefined in `Olmo2MLP`, so the linter automatically created a `Olmo2MLP` class similar to `OlmoMLP`. It is identical to the code below if it was explicitly written in `modular_olmo2.py`.
