[pytorch]'list' object is not callable

想训练一个网络，网络本身很简单结构，无关的部分我都注释了，如下：

 class ResnetGenerator(nn.Module):
     def __init__(self, input_nc=3, output_nc=3, ngf=8, n_blocks=4):
         super(ResnetGenerator, self).__init__()
         self.resblock = []
         for i in range(n_blocks):
             self.resblock += [ResidualBasic_in(output_nc)]
     def forward(self, y_hr, x_hr):
         y_hr = self.resblock(torch.add(x_hr, y_hr))
         return y_hr

但是报错了，报错信息如下：
TypeError: 'list' object is not callable

原因是代码中的resblock我定义成了一个list，而非一个nn.Module模块，需要使用nn.Sequential

修改后的代码如下，只需要在第7行加上self``.resblock = nn.Sequential(*``self``.resblock)

 class ResnetGenerator(nn.Module):
     def __init__(self, input_nc=3, output_nc=3, ngf=8, n_blocks=4):
         super(ResnetGenerator, self).__init__()
         self.resblock = []
         for i in range(n_blocks):
             self.resblock += [ResidualBasic_in(output_nc)]
         self.resblock = nn.Sequential(*self.resblock)
     def forward(self, y_hr, x_hr):
         y_hr = self.resblock(torch.add(x_hr, y_hr))
         return y_hr
