Pickling the knowledge base

See original GitHub issue

I have a project, where FastCFG runs for several minutes. To speed up things, I wanted to serialize out (pickle) project.kb but got an exception.

Is there a standard way of serializing the knowledge base, so I don’t need to recalculate it every time I load the project? If not, could you add support to it?

Using pickle’s default protocol is going to lead to sadness. Have you tried the latest protocol? That’d be pickle.dump(kb, outfile, -1)
