your graphviz could work?

ghost commented 8 years ago

Hi, I am having the same issue : graph_test

The graph is actually created in the current folder despite the segmentation error. graph_test1

So I tested graphviz with a simple graph created in a text file: graph_test2 and got a correct graph: graph

graphviz seems fine, I can't figure out why Torch crashes every time I call graph.dot.

Hi, guys. I have the same issue. Whenever I call graph.dot, torch crashes and I get segmentation fault. And graphviz works fine in bash. Do you guys figure it out?

Specifically, the package seems loading graphviz correctly.

I tried graphvizOk, graphviz = pcall(function() return ffi.load('libgvc.so.6', true) end) cgraphOk, cgraph = pcall(function() return ffi.load('libcgraph.so.6', true) end) Both graphvizOk and cgraphOk returns true.

I get the same problem over a brand new centos 7.3 with a clean recent torch installation...following the documentation....

I am trying to type the same as in youtube practice 4.2 video, step by step ...
