TRF013

PreTrainedModel __init__ must call self.post_init().

What it does

Checks that every PreTrainedModel subclass defining __init__ calls self.post_init(). In modular files super().__init__() counts, since it propagates the parent’s post_init.

Why is this bad?

post_init does essential finalization (weight init, gradient checkpointing setup, …); skipping it causes subtle runtime bugs.

Example

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