when i run flow_datasets.py file in the Neural bipartite matching, i get this error: i have tried to resolve it but until now i have failed.some assistance pliz. Plus how can support this page in terms of donation, can it accept visa card payment.

TypeError: Can't instantiate abstract class SingleIterationDataset with abstract method len

Hello Prof, I embarked on understanding Nueral bipartite matching as
clearly explained in your paper. i have tested 98% of your code and its a
success. i have only met the error: IndexError: index 6 is out of bounds
for dimension 0 with size 6 and it points to utils.py script.iam testing on different new graph data.The error is in this function:::::
def create_inv_edge_index(batch_size, size, edge_index):iei =
torch.full((batch_sizesize, batch_sizesize), -100, dtype=torch.long)for i
in range(len(edge_index[0])):iei[edge_index[0][i]][edge_index[1][i]] =
ireturn iei

part of the output where the error is displayed is shown below:
tedge_index = torch.tensor(edge_index).clone().detach()
