怎么在Linear里设置因变量取值只能为整数

可以使用 torch.nn.functional.relu() 函数将因变量的值取整。具体实现代码如下所示:
```python
import torch.nn as nn
import torch.nn.functional as F
class LinearInt(nn.Module):
def __init__(self, in_features, out_features, bias=True):
super(LinearInt, self).__init__()
self.in_features = in_features
self.out_features = out_features
self.weight = nn.Parameter(torch.Tensor(out_features, in_features))
if bias:
self.bias = nn.Parameter(torch.Tensor(out_features))
else:
self.register_parameter('bias', None)
self.reset_parameters()
def reset_parameters(self):
nn.init.kaiming_uniform_(self.weight, a=math.sqrt(5))
if self.bias is not None:
fan_in, _ = nn.init._calculate_fan_in_and_fan_out(self.weight)
bound = 1 / math.sqrt(fan_in)
nn.init.uniform_(self.bias, -bound, bound)
def forward(self, input):
output = F.linear(input, self.weight, self.bias)
return F.relu(output).round_()
```
上述代码中,LinearInt 是一个继承自 nn.Module 的自定义层,其 forward() 函数对输出结果应用了 relu() 函数,从而将因变量的值限定为整数。使用该层可以实现在 Linear 层中设置因变量取值只能为整数的功能。
