+angle = AnglE.from_pretrained('NousResearch/Llama-2-7b-hf', pretrained_lora_path='SeanLee97/angle-llama-7b-nli-v2')
+angle.set_prompt()
+print('prompt:', angle.prompt)
+vec = angle.encode({'text': 'hello world'}, to_numpy=True)
+print(vec)
+vecs = angle.encode([{'text': 'hello world1'}, {'text': 'hello world2'}], to_numpy=True)
+print(vecs)
+```
