[SOLVED] Python argument types did not match C++ signature

I have been playing around with the inference module from graph-tool a bit and tried to replicate a section of code from the cookbook section. When running gt.mcmc_equilibrate(state, wait=1000, mcmc_args=dict(niter=10)) I however get an error message.

It seems to revolve around Python argument types not matching C++ signatures. Having done some searching this seems to come up when using different compilers for different modules (?). In this case I am however running the package as downloaded from apt-get (2.19 (commit da041f33, Sat Nov 12 17:27:48 2016 +0100)) so I was surprised to see it. The same error also gets thrown if running it on a compiled version of the source code (2.20dev (commit 01432d60, Sun Jan 15 19:54:52 2017 +0000)).

Does anybody know what is going wrong here/how I could fix it?

This is the relevant code snippet:

import graph_tool.all as gt
import timeit, os
import cPickle as pickle
import numpy as np

g = gt.load_graph('graph_no_multi_reac_type.gt')
gt.remove_parallel_edges(g)

state = gt.minimize_nested_blockmodel_dl(g, deg_corr=True)

# We will first equilibrate the Markov chain
gt.mcmc_equilibrate(state, wait=1000, mcmc_args=dict(niter=10))

And this is the error message I get:

Traceback (most recent call last):
