python - Pycharm 提示对 pytorch 的 nn.ModuleList 对象使用 [] 运算符

Question

Pycharm 的类型检查提示以下代码块(取自 pytorch's docs ):

    import torch.nn as nn
    class MyModule(nn.Module):
    def __init__(self):
        super(MyModule, self).__init__()
        self.linears = nn.ModuleList([nn.Linear(10, 10) for i in range(10)])

    def forward(self, x):
        # ModuleList can act as an iterable, or be indexed using ints
        for i, l in enumerate(self.linears):
            x = self.linears[i // 2](x) + l(x)
        #                   ^---------- complains here about:
        # Cannot find reference '[' in 'input:(Any, ...), kwargs:dict) -> Any'
        return x

有没有办法解决这个问题而不抑制它？
