Dear R-GSN authors,
I have a question about how to calculate attention score in this part.
def message(self, edge_index_i, x_i, x_j, src_node_type_j, edge_type: int , a=None): if a == None: res = x_j else: if x_i.size(0) == 0: return self.rel_lins[edge_type](x_j) a = softmax(a, edge_index_i) res = a.unsqueeze(-1) * self.rel_lins[edge_type](x_j) ######## Message Transform return res
In this part, there is this line
a = softmax(a, edge_index_i)
I think edge_index_i is the index of target type node. Shouldn't it be edge_index_j(the index of source type node)? Because I checked your paper, the attention is calculated by:
I'm a little bit confused. Could you kindly explain this part please?
Thanks!
Hi,Thank you for releasing your code. When I run R-GSN get error "RuntimeError: CUDA out of memory. Tried to allocate 562.00 MiB (GPU 1; 10.76 GiB total capacity; 8.98 GiB already allocated; 470.56 MiB free; 9.19 GiB reserved in total by PyTorch)".
I try to reduce the batch size. batch_size
has been reduced to 64 and test_batch_size
has been reduced to 4, I still get the same error. I used GeForce RTX 2080, can u tell me why and how to fix it, thanks a lot!
