WebApr 12, 2024 · (2条消息) RuntimeError: expected scalar type Double but found Float_edward_zcl的博客-CSDN博客。需要修改data.x和data.edge_index的数据类型以适配。* pyG要求data.edge_index为int64或long，我一开始用的是float也报错了。报错为期待的张量类型是double但是输入的是float，可以将模型所有的层的输入输出类型打印出来。 Web给出的答案是如果要用的pyg的确定算法，必须用SparseTensor类型的领接矩阵代替原来的edge_index的做法。 按照教程作出相应的修改之后，再次运行确定下，发现模型每次的run的都是准确的结果。 解决方法 在代码开头调用这段，如果涉及到了numpy.random或者random等其他三方库，也记得加上随机种子
