Usage

from angle_emb import AnglE, Prompts

angle = AnglE.from_pretrained('NousResearch/Llama-2-7b-hf', pretrained_lora_path='SeanLee97/angle-llama-7b-zhnli-v1')
# 请选择对应的 prompt，此模型对应 Prompts.B
print('All predefined prompts:', Prompts.list_prompts())
angle.set_prompt(prompt=Prompts.B)
print('prompt:', angle.prompt)
vec = angle.encode({'text': '你好世界'}, to_numpy=True)
print(vec)
vecs = angle.encode([{'text': '你好世界1'}, {'text': '你好世界2'}], to_numpy=True)
print(vecs)
