Python参数类型与C++；签名

我一直在使用graph tool中的推理模块，并尝试从cookbook部分复制一段代码。当运行

gt.mcmc\u均衡（状态，等待=1000，mcmc\u args=dict（niter=10））时，

I收到一条错误消息

它似乎围绕着不匹配C++签名的Python参数类型。在对不同的模块使用不同的编译器（？）时，进行了一些搜索之后，似乎会出现这种情况。然而，在本例中，我正在运行从apt get下载的包（2.19（commit da041f33，Sat Nov 12 17:27:48 2016+0100）），因此我很惊讶地看到了它。如果在源代码的编译版本（2.20dev（commit 01432d60，Sun Jan 15 19:54:52 2017+0000））上运行它，也会抛出相同的错误

有人知道这里出了什么问题/我如何解决它吗

这是相关的代码片段：

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))

这是我收到的错误信息：

该代码不起作用，因为在通过执行mcmc平衡之前必须启用采样

state = state.copy(sampling=True)

正如这里指出的
