想在本地部署翻译模型，在 Fengshenbang-LM\fengshen\models\deltalm 目录下，执行的代码为官方例子
from modeling_deltalm import DeltalmForConditionalGeneration
from transformers import AutoTokenizer

model = DeltalmForConditionalGeneration.from_pretrained("IDEA-CCNL/Randeng-Deltalm-362M-Zh-En")
tokenizer = AutoTokenizer.from_pretrained("microsoft/infoxlm-base")

text = "尤其在夏天,如果你决定徒步穿越雨林,就需要小心蚊子。"

inputs = tokenizer(text, max_length=512, return_tensors="pt")

generate_ids = model.generate(inputs["input_ids"], max_length=512)
tokenizer.batch_decode(generate_ids, skip_special_tokens=True, clean_up_tokenization_spaces=False)[0]

from modeling_deltalm import DeltalmForConditionalGeneration报错
ImportError: attempted relative import with no known parent package

谢谢
