机器学习PAI使用EasyRec推荐算法框架时，这在input上怎么写配置？

机器学习PAI使用EasyRec推荐算法框架时，如果在一条样本中，其中一个序列中，每个元素是：q1 对应5个item正样本。infer的时候每个元素正常meanpooling训练的时候，q1和这5个正样本计算对比loss，负样本用全局随机负采样。这在input上怎么写配置？

阿里云机器学习PAI开源中文NLP算法框架EasyNLP，助力NLP大模型落地

作者：临在、岑鸣、熊兮一导读随着 BERT、Megatron、GPT-3 等预训练模型在NLP领域取得瞩目的成果，越来越多团队投身到超大规模训练中，这使得训练模型的规模从亿级别发展到了千亿甚至万亿的规模。然而，这类超大规模的模型运用于实际场景中仍然有一些挑战。首先，模型参数量过大使得训练和推理速度过慢且部署成本极高；其次在很多实际场景中数据量不足的问题仍然制约着大模型在小样本场景中的应用，提高....
