出错：TypeError: cat() received an invalid combination of arguments - got (Tensor, Tensor, dim=int),

import torch

w = torch.Tensor(6,10,1)
h = torch.Tensor(6,10,1)
#w和h是大小为6*10*1的张量

将w和h在第二维度上（最后那个1）拼接起来，使用torch.cat()操作。

new = torch.cat(w,h,dim=2)

会出现报错：

TypeError: cat() received an invalid combination of arguments - got (Tensor, Tensor, dim=int), but expected one of:
 * (tuple of Tensors tensors, int dim, *, Tensor out)
 * (tuple of Tensors tensors, name dim, *, Tensor out)

TypeError: cat() received an invalid combination of arguments - got (Tensor, Tensor, dim=int), but expected one of:
 * (tuple of Tensors tensors, int dim, *, Tensor out)
 * (tuple of Tensors tensors, name dim, *, Tensor out)

这是因为在cat操作中忘记加括号了，不能多加也不能少加括号。最后new的大小为6*10*2

#报错代码
new = torch.cat(w,h,dim=2)
#正确代码
new = torch.cat((w,h),dim=2)
