Consider testing this pull request before merging by loading the model from this PR with the revision argument:

from sentence_transformers import CrossEncoder

# TODO: Fill in the PR number
pr_number = 2
model = CrossEncoder(
    "cross-encoder/stsb-roberta-base",
    revision=f"refs/pr/{pr_number}",
    backend="onnx",
    model_kwargs={"file_name": "model_qint8_avx512_vnni.onnx"},
)

# Verify that everything works as expected

    "Mars, known for its reddish appearance, is often referred to as the Red Planet.",
    "Jupiter, the largest planet in our solar system, has a prominent red spot.",
    "Saturn, famous for its rings, is sometimes mistaken for the Red Planet."

scores = model.predict([(query, passage) for passage in passages])
