一般是连续的 {{ 或者 }} 报错，你变成一个，可能是语法的问题

$$\begin{array}{ll} out(N_i, C_{out_j}) = bias(C_{out_j}) + \sum_{{k}=0}^{C_{in}-1} weight(C_{out_j}, k) \star input(N_i, k) \end{array}$$

修改位置：\sum_{{k}=0} => \sum_{k=0}

$$\begin{array}{ll} out(N_i, C_{out_j}) = bias(C_{out_j}) + \sum_{k=0}^{C_{in}-1} weight(C_{out_j}, k) \star input(N_i, k) \end{array}$$
