Mismatch device.

The error is:

dgl._ffi.base.DGLError: Cannot assign node feature "feat" on device cpu to a graph on device cuda:0. Call DGLGraph.to() to copy the graph to the same device.

Line 212:

self.symmetrical_global_graph = self.symmetrical_global_graph.to(self.device)
for k, v in features.items():
