Dense Subgraphs

Hi.

While running:

sub = list(range(20, 30)) plot.graph(pl_graph, sub) in https://strawberryfields.ai/photonics/apps/run_tutorial_dense.html , I get: ValueError: source code string cannot contain null bytes

Hi @_risto! It looks like the bottom of the error message has been cutoff, would you be able to post the full traceback :slight_smile:
