object has no attribute

Question

代码

import torch
from torch import nn

input = torch.tensor([[1, 2, 0, 3, 1],
                      [0, 1, 2, 3, 1],
                      [1, 2, 1, 0, 0],
                      [5, 2, 3, 1, 1],
                      [2, 1, 0, 1, 1]], dtype=torch.float32)
input = torch.reshape(input, (-1, 1, 5, 5))
print(input.shape)

class jiang(nn.Module):
    def __int__(self):
        super(jiang, self).__int__()
        self.maxpool1 = torch.nn.MaxPool2d(kernel_size=3,
                                           ceil_mode=True)

    def forward(self, input):
        output = self.maxpool1(input)
        return output

wen = jiang()
wen(input)

错误类型

拜谢大佬指点

Answer 1

__init__ ，不是 __int__ 。
