Hi Sumit, Very likely you are not using python3. “@“ is only introduced in python3 as matrix multiplication.

seems that you are not properly installing pytorch cuda version. ' torch.cuda.FloatTensor is not enabled' Original Message Sender:Sumit Purohitnotifications@github.com Recipient:snap-stanford/GraphRNNGraphRNN@noreply.github.com Cc:Jiaxuan229331845@qq.com; Mentionmention@noreply.github.com Date:Monday, Jul 2, 2018 14:55 Subject:Re: [snap-stanford/GraphRNN] Unable to run the test program (#1) Thanks for the pointer. That error is fixed using python3. Next i get an error related to CUDA.FloatTensor On my Mac i have set export NO_CUDA=1 but i still get following error. python3 main.py /Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/importlib/_bootstrap.py:222: RuntimeWarning: compiletime version 3.6 of module 'tensorflow.python.framework.fast_tensor_util' does not match runtime version 3.5 return f(*args, **kwds) CUDA 1 File name prefix GraphRNN_RNN_grid_4_128_ graph_validate_len 199.5 graph_test_len 215.0 total graph num: 100, training set: 80 max number node: 361 max/min number edge: 684; 180 max previous node: 40 train and test graphs saved at: ./graphs/GraphRNN_RNN_grid_4_128_test_0.dat /XXXX/GraphGeneration/GraphRNN/model.py:299: UserWarning: nn.init.xavier_uniform is now deprecated in favor of nn.init.xavier_uniform_. nn.init.xavier_uniform(param,gain=nn.init.calculate_gain('sigmoid')) ..........
