Python 参数类型与 C++ 签名不匹配

【中文标题】Python 参数类型与 C++ 签名不匹配

【英文标题】：Python argument types did not match C++ signature

【问题描述】：

我一直在使用图形工具中的推理模块，并尝试复制食谱部分中的一段代码。但是，在运行 gt.mcmc_equilibrate(state, wait=1000, mcmc_args=dict(niter=10)) 时，我会收到一条错误消息。

它似乎围绕着与 C++ 签名不匹配的 Python 参数类型展开。在对不同的模块（？）使用不同的编译器时，似乎会出现一些搜索。但是，在这种情况下，我正在运行从 apt-get (2.19 (commit da041f33, Sat Nov 12 17:27:48 2016 +0100)) 下载的包，所以我很惊讶地看到它。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，也会引发相同的错误。

有人知道这里出了什么问题/我该如何解决？

这是相关代码sn -p：

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))

这是我收到的错误消息：

【参考方案1】：

代码不起作用，因为在执行 mcmc 平衡之前必须启用采样

state = state.copy(sampling=True)

正如这里指出的http://main-discussion-list-for-the-graph-tool-project.982480.n3.nabble.com/self-state-couple-state-state-state-entropy-args-Python-argument-types-did-not-match-C-signature-td4026975.html#a4026979
