Hi muhan, 我最近使用模型时遇到这个问题不知道怎么解决： Traceback (most recent call last): File "C:\Users\Miao Jiangbei\Desktop\计算机\机器学习\Lab\SEAL\Python\Main.py", line 162, in train_graphs, test_graphs, max_n_label = links2subgraphs( File "C:\Users\Miao Jiangbei\Desktop\计算机\机器学习\Lab\SEAL\Python\util_functions.py", line 135, in links2subgraphs train_graphs = helper(A, train_pos, 1) + helper(A, train_neg, 0) TypeError: unsupported operand type(s) for +: 'NoneType' and 'NoneType' 我不知道为什么会得到'NoneType'

Can you try to set a breakpoint before g_list in helper() function to see what it prints? Seems the helper does not return any subgraphs, not even an empty list.
