Faced Issue while reproducing the results

[AbhishekG-1plus]

I got the following error after following the step 1 and step 2 for the installation.
ImportError: dlopen(/Users/abhishekgadekar/opt/anaconda3/envs/gnn_lspe/lib/python3.7/lib-dynload/_ctypes.cpython-37m-darwin.so, 0x0002): Library not loaded: @rpath/libffi.6.dylib
This error occured when I ran the following command:

Run the main file (at the root of the project)

python main_ZINC_graph_regression.py --config 'configs/GatedGCN_ZINC_LSPE.json' # for CPU
python main_ZINC_graph_regression.py --gpu_id 0 --config 'configs/GatedGCN_ZINC_LSPE.json' # for GPU

It would be really helpful if you could provide a fix for this issue. I also checked by installing libffi by using pip, but that also couldn't solve the issue.
