Tip:

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

from sentence_transformers import SentenceTransformer

# TODO: Fill in the PR number
pr_number = 2
model = SentenceTransformer(
    "shibing624/text2vec-base-chinese",
    revision=f"refs/pr/{pr_number}",
    backend="openvino",
    model_kwargs={"file_name": "openvino_model_qint8_quantized.xml"},
)

# Verify that everything works as expected
embeddings = model.encode(["The weather is lovely today.", "It's so sunny outside!", "He drove to the stadium."])
print(embeddings.shape)

similarities = model.similarity(embeddings, embeddings)
print(similarities)

效果损失太大,emb模型不建议量化。Quantization is not recommended for embedding models as it results in significant performance degradation.
