Python 参数类型与 C++ 签名不匹配
Python argument types did not match C++ signature
我一直在尝试使用 graph-tool 中的推理模块，并尝试从 cookbook 部分复制一段代码。然而，当 运行 gt.mcmc_equilibrate(state, wait=1000, mcmc_args=dict(niter=10)) 我收到一条错误消息。
它似乎围绕着 Python 与 C++ 签名不匹配的参数类型。完成一些搜索后，当对不同的模块使用不同的编译器时，这似乎会出现（？）。然而，在这种情况下，我是 运行 从 apt-get 下载的包（2.19（提交 da041f33，星期六，11 月 12 日 17:27:48 2016 +0100））所以我很惊讶地看到它。如果 运行 它在源代码的编译版本上也会抛出相同的错误（2.20dev（提交 01432d60，Sun Jan 15 19:54:52 2017 +0000））。
有人知道出了什么问题吗here/how我可以解决吗？
这是相关的代码片段：

# We will first equilibrate the Markov chain
