AttributeError: 'DataFrame' object has no attribute 'append'. Did you mean: '_append'?

To Reproduce
Steps to reproduce the behavior:

1. Use the provided example code from AutoGL documentation to produce a customized dataset
   

2. The pip installed old version does not have this problem.

After changing the line in the file" _general_static_graph_default_implementation.py", line 683, in _set_edges:
self.__heterogeneous_edges_data_frame.append(
into:
self.__heterogeneous_edges_data_frame._append(
there's no error message again.

I had the same error! Commenting here for better visibility. The same code change, fixed it for me! Thanks, @Gankuaidian Ideally the code in AutoGL should be changed to be used with pd.concat
