本文解决了一个常见的PyTorch模型训练错误，即期望长整型目标变量但收到浮点型。提供了两种解决方案，一种是使用torch.LongTensor转换目标变量，另一种是通过指定设备和数据类型为int64来转换。

背景：训练模型的时候报错Expected object of scalar type Long but got scalar type Float

解决：

方法一：
targets =torch.LongTensor(targets)
方法二：
targets = targets.to(self.device,dtype=torch.int64)

确定要放弃本次机会？

看看哪个是int整形的，用target.float()也能解决

这个错误就是数据类型不对，定位到代码中就是下面这一行，所以要么是segment_image不对，要么就是out_image不对 segment_image数据类型已经是float，所以是out_image的错误，转换成数据类型为long即可 http://t.csdn.cn/A64Qzhttp://t.csdn.cn/A64Qz ...

在pytorch中float32为float类型，而float64则为double类型，注意tensor的数据类型。可以通过指定数据类型来获得所需要的类型数据。 torch.zeros([self.batch_size, self.num_layers, self.hidden_size], dtype=torch.float32) # float torch.zeros([self.batch_size, self.num_layers, self.hidden_size], dtype=t
