TYPE ERROR Fine Tuning, metric evaluate, metric.compute

Hi,

Im nearing the end of fine tuning a model, and I am looking to evaluate the model with this code:
import evaluate
metric = evaluate.load(“super_glue”, “boolq”)
metric.compute(predictions=preds, reference=predictions.label_ids)

but, i get this error
TypeError: object of type ‘NoneType’ has no len()

is there any hope? I have no idea where to begin. Thank you for any guidance or help. Be really appreciated.
