Question

当我运行任何pystan代码时，输出是我所期望的，但是却出现了警告。

我已经尝试更新pystan和cython，因为警告墙中提到了这些。我的pystan现在是2.17.1版和cython 0.29.2版。我正在运行python3.7。

import pystan
model_code = 'parameters {real y;} model {y ~ normal(0,1);}'
model = pystan.StanModel(model_code=model_code)  # this will take a minute
y = model.sampling(n_jobs=1).extract()['y']
y.mean()  # should be close to 0

我收到的错误消息开始于：

这值得担心吗？如果没有，如何专门禁用这些警告，而不是从代码的其他部分禁用这些警告？如果是这样，我应该怎么改变。

编辑：阅读问题Cython Numpy warning about NPY_NO_DEPRECATED_API when using MemoryView之后，我仍然不知道如何安全地禁用此警告。

如何使用任何pystan代码解决或抑制警告墙
