Plot LSTM network

Does anyone plot LSTM network successfully?

I follow the tutorial to construct LSTM network:

When I call Visualization.plotNetwork(…).render(…), the program execution does not stop so that I can’t get any plotting.
Does anyone know how to plot the network correctly?

What are you passing to plotNetwork()? My guess is that you’re unrolling the LSTM for a very long sequence.

You are right. Thank you.

I tried to modify the engine parameter and got the plotting successful.
But the plotting is huge and unreadable.
I just want to plot the network roughly like this page:
