我有Tensor的列表

t_list=[tensor([[1],
         [1],
         [1]]),
 tensor([[1],
         [1],
         [1]]),
 tensor([[1],
         [1],
         [1]])]

想把它转换成

[tensor([[1,0,0],
         [1,0,0],
         [1,0,0]]),
 tensor([[1,0,0],
         [1,0,0],
         [1,0,0]]),
 tensor([[1,0,0],
         [1,0,0],
         [1,0,0]])]

我试过这个密码

import torch
z= torch.zeros(1,2)
for i, item in enumerate(t_list):
    for ii, item2 in enumerate(item):
        unsqueezed = torch.unsqueeze(item2,0)
        cat1 = torch.cat((unsqueezed,z),-1)
        squeezed = torch.squeeze(cat1,0)
        t[i][ii] = squeezed

但得到了这个错误

RuntimeError: expand(torch.FloatTensor{[5]}, size=[]): the number of sizes provided (0) must be greater or equal to the number of dimensions in the tensor (1)

我不知道该怎么办
