When I run the superpixel graph_classification experiment, I got the error"'Column' object has no attribute 'deferred_dtype'"

Just as the title said, when I run the 'main_superpixels_graph_classification.py', I got the error"'Column' object has no attribute 'deferred_dtype'" in the file 'superpixels.py' when getting the feature of the graph data at lin290.
line290for idx, graph in enumerate(graphs):
line291 graphs[idx].ndata['feat'] = graph.ndata['feat'].float()
line292 graphs[idx].edata['feat'] = graph.edata['feat'].float()
line293batched_graph = dgl.batch(graphs)
Unfortunately, I can't tackle this by myself.
Have you encountered the same error? I indeed need your help. Thank you greatly!

Hi @weihai-98, are you using the correct version of DGL? It may be that things have changed across new releases of DGL.
