How to get predictions after evaluation phase in a callback

Gladiator · April 25, 2022, 6:08am

I want to log prediction distribution after each evaluation phase to Weights & Biases. I thought of adding a callback to do this, but couldn’t find anything which allows me to access predictions in on_evaluate method to do so. Is there any way to achieve this or am I missing something ?

If you want to get the predictions back, you should use Trainer.predict().

github.com

huggingface/transformers/blob/72728be3dbca26c70dddc8b724eb2c8d901e97dc/src/transformers/trainer.py#L2343-L2350

      
        
            def predict(
                self, test_dataset: Dataset, ignore_keys: Optional[List[str]] = None, metric_key_prefix: str = "test"
            ) -> PredictionOutput:
                """
                Run prediction and returns predictions and potential metrics.
            
            
    Depending on the dataset and your use case, your test dataset may contain labels. In that case, this method
                will also return metrics, like in `evaluate()`.
