torch.view()

import torch
conf_data=torch.tensor([[[1, 2,3], [4,5,6]], [[7,8,9],[10,11,12]],[[10, 20,30], [40,50,60]], [[70,80,90],[100,110,120]]])

conf_t=torch.tensor([1,2,3,4])
conf_data = conf_data.view(-1, 3)

conf_t = conf_t.view(-1)


print(conf_data)
print(conf_t)

结果：

tensor([[  1,   2,   3],
        [  4,   5,   6],
        [  7,   8,   9],
        [ 10,  11,  12],
        [ 10,  20,  30],
        [ 40,  50,  60],
        [ 70,  80,  90],
        [100, 110, 120]])
tensor([1, 2, 3, 4])
