sun20AM 2023-11-28 2:52:54 1 DeepRec是阿里巴巴开源的一套深度学习推荐系统框架,它提供了多种数据读取接口,包括读取本地文件、HDFS、ODPS等。但是,DeepRec并没有提供直接读取ODPS TableRecordDataset的接口。 如果你想在DeepRec中使用ODPS TableRecordDataset,你需要先将数据从ODPS TableRecordDataset转换为其他格式,然后再使用DeepRec的数据读取接口读取这个转换后的数据。 具体来说,你可以使用ODPS的SDK来读取ODPS TableRecordDataset,然后将数据转换为JSON或者CSV格式,然后再使用DeepRec的数据读取接口读取这个转换后的数据。 以下是一个基本的示例: “`pythonimport
