通过查阅引用,我们可以得知torch.cuda.FloatTensor和torch.FloatTensor之间的类型不匹配错误。要将torch.cuda.FloatTensor转换为long类型,可以使用`long()`函数进行类型转换。例如,可以使用以下代码将torch.cuda.FloatTensor转换为long类型:
```
cuda_tensor = torch.cuda.FloatTensor([1, 2, 3])
long_tensor = cuda_tensor.long()
```
请注意,这里的`cuda_tensor`是torch.cuda.FloatTensor类型的张量,通过调用`long()`函数,我们将其转换为了long类型的张量`long_tensor`。
另外,引用指出,在使用交叉熵损失函数时,目标值(target)应该是整数类型,以便将其转换为索引值进行one-hot编码。因此,在将torch.cuda.FloatTensor转换为long类型之前,确保目标值是整数类型。
综上所述,要将torch.cuda.FloatTensor转换为long类型,可以使用`long()`函数进行类型转换,并确保目标值是整数类型。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
