为了发现dask,我目前正在实现一个K-Means算法。 要更新方法,我想使用groupBy,但我必须将我的dask.array转换为dask.dataframe,然后返回到dask.array:

    'use strict';
module.exports = function (sequelize, DataTypes) {
    var announcement = sequelize.define('announcements', {
        id: {
            type: DataTypes.INTEGER,
            primaryKey: true,
            autoIncrement: true
        },
        title: DataTypes.STRING,
        description: DataTypes.TEXT,
        likes: DataTypes.INTEGER
    }, {
        classMethods: {
            associate: function (models) {
                /**
                 * an announcement is created by only one user
                 */
                announcement.belongsTo(models.users, {
                  as: 'Owner'
                });
            }
        }
    });
    return announcement;
}

如果没有转换,有没有办法做到这一点?
