Hi,

When I ran the sample code, I encountered the following error

Traceback (most recent call last): File "gcn_LR2_LR_as_nega_big.py", line 75, in model = Model(inputs=[X_in, A_in], outputs=output) File "/Users/zhangl18/opt/anaconda3/envs/tf/lib/python3.7/site-packages/keras/legacy/interfaces.py", line 91, in wrapper return func(*args, *kwargs) File "/Users/zhangl18/opt/anaconda3/envs/tf/lib/python3.7/site-packages/keras/engine/network.py", line 94, in init self._init_graph_network(args, **kwargs) File "/Users/zhangl18/opt/anaconda3/envs/tf/lib/python3.7/site-packages/keras/engine/network.py", line 241, in _init_graph_network self.inputs, self.outputs) File "/Users/zhangl18/opt/anaconda3/envs/tf/lib/python3.7/site-packages/keras/engine/network.py", line 1434, in _map_graph_network tensor_index=tensor_index) File "/Users/zhangl18/opt/anaconda3/envs/tf/lib/python3.7/site-packages/keras/engine/network.py", line 1421, in build_map node_index, tensor_index) File "/Users/zhangl18/opt/anaconda3/envs/tf/lib/python3.7/site-packages/keras/engine/network.py", line 1421, in build_map node_index, tensor_index) File "/Users/zhangl18/opt/anaconda3/envs/tf/lib/python3.7/site-packages/keras/engine/network.py", line 1421, in build_map node_index, tensor_index) File "/Users/zhangl18/opt/anaconda3/envs/tf/lib/python3.7/site-packages/keras/engine/network.py", line 1393, in build_map node = layer._inbound_nodes[node_index] AttributeError: 'NoneType' object has no attribute '_inbound_nodes'

It seems that GraphConv is not recognized as a keras layer. I'm wondering how you resolved this issue. Thank you.

plz used the old version of spektral as "spektral"github suggests.

Could you kindly specify which version of your scipy and spektral?
