预测结果不一致

您好，我在使用lightgbm进行预测时，多次预测的结果不一致，请问可能是什么原因呢？
前提声明：
1. 在训练过程中声明了seed=42，固定了随机种子
2. 测试过程中使用的是同一个权重，同一个测试文件

请问各位大佬，是什么原因导致的呢？

The issue names no files, tests, or entry points. Start by collecting a minimal reproducible example, including the LightGBM version, prediction code, model format, and relevant training settings. Done means identifying a reproducible cause for the differing predictions and documenting the required fix or conditions.
