你好，我用开源的SpatialNet和OSpatialNet分别训练了语音分离的模型，SpatialNet的表现确实非常惊艳，但是OSpatialNet出现训练时loss下降的比较正常，但是测试集中得到的结果非常差。猜测可能是出现过拟合的问题？

您好，感谢关注我们的工作。对于oSpatialNet，我们主要遇到的主要问题是长度外推问题。泛化问题我们没有遇到，您这个是不是泛化问题需要进一步研究、分析

好的，我再去研究研究

好吧，其实并不是过拟合的问题，而是训练和推理时模型的超参数不匹配导致的。训练时采用的MultiheadAttention的num_heads为4，而推理时采用的num_heads却是2，从而导致的推理结果差。。。
