dspy.Prediction

dspy.Prediction(*args, **kwargs)

基类: Example

包含DSPy模块输出的预测对象。

Prediction 继承自 Example。

为了实现反馈增强的评分，Prediction支持对带有score字段的Predictions进行比较操作 (<, >, <=, >=)。这些比较操作 会将'score'值作为浮点数进行比较。对于相等性比较，如果两个Predictions的底层数据存储相等（继承自Example），则它们被视为相等。

对于带有'score'字段的Predictions，还支持算术运算（+、/等），这些运算作用于分数值。
