Compiling Model

[linanzhang]

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

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?
