导出模型时报错 'structbert is not in the exporters regist

导出 FAQ问答模型（'damo/nlp_structbert_faq-question-answering_chinese-base' ）的时候提示，

KeyError: 'structbert is not in the exporters registry group faq-question-answering. Please make sure the correct version of ModelScope library is used'

导出的语句是：

from modelscope.models import Model
model_id = 'damo/nlp_structbert_faq-question-answering_chinese-base'
model = Model.from_pretrained(model_id)

from modelscope.exporters import Exporter
# shape参数用来生成dummy inputs
# 在NLP领域中一般len(shape) == 2, 分别代表batch_size和sequence_length
output_files = Exporter.from_model(model).export_onnx(shape=(2, 256), opset=13, output_dir='/tmp')
print(output_files) # {'model': '/tmp/model.onnx'}

我刚接触python，都是按照文档拷贝的代码，求大神帮忙看看这个问题，谢谢。
