TRF013

PreTrainedModel __init__ must call self.post_init().

What it does

Checks that every PreTrainedModel subclass with an __init__ method calls self.post_init(). In modular files, calling super().__init__() is also accepted since it propagates post_init from the parent.

Why is this bad?

post_init performs essential finalization (weight initialization, gradient checkpointing setup, etc.). Omitting it causes subtle runtime bugs.

Example

 class AcmeModel(AcmePreTrainedModel):
     def __init__(self, config):
         super().__init__(config)
         self.layers = nn.ModuleList(...)
+        self.post_init()
