Hi, It turns out the cause of that error is the python version. I’m using python 3.5.5 but the f string which is giving syntax error is recently added in python 3.6. If it’s really due to the version, I think it should be edited because this error occurs at import torch_geometric.nn from message_passing.py as well.

File “/opt/conda/envs/py35/lib/python3.5/site-packages/torch_geometric/nn/conv/init.py”, line 1, in <module> from .message_passing import MessagePassing

File “/opt/conda/envs/py35/lib/python3.5/site-packages/torch_geometric/nn/conv/message_passing.py”, line 88 (f’Encountered node tensor with size ’ ^ SyntaxError: invalid syntax
