使用Rodeo IDE时不导入Python“statsmodel”

Question

我安装了Anaconda，然后安装了Rodeo (使用他们网站上的安装文件)。然而，当我运行一个脚本时，我得到了下面的错误。有问题的线是：

import statsmodels.api as sm

奇怪的是，使用Spyder2集成开发环境可以很好地运行这段代码。

有什么建议吗？

Answer 1

scipy中的多处理库有一个依赖关系，它会查找可用的核心数量。我们在最新版本中添加了对此的检测，但在此期间，您可以手动设置环境变量：

import os
os.environ["NUMBER_OF_PROCESSORS"] = "2"
