我正在努力让PYMC3在windows上正确安装。我曾尝试通过

conda安装-c conda forge pymc3

使用Anaconda包，并根据文档在虚拟环境中仅使用pip

它似乎安装正常，但在运行导入pymc3时失败，出现以下错误。研究表明，可能有一些依赖性正在被忽略

EDIT2:我切换到Python2.7环境，它似乎工作正常。必须安装，但之后一切正常

不过，如果能在3.6版本中使用，那就太好了。有人想过吗？

好的，我设法拼凑了一个安装程序

使用

conda install-c conda forge pymc3

进行依赖关系管理时，我运气不佳，无法确定编译器的位置/路径等是否存在问题。因此，我从一开始就重新安装了

我选择了水蟒3号（而不是2号），效果很好

1）在安装Theano之前，我一直遵循这里的环境设置。但是我安装的不是建议的版本，而是最新的

conda install-c rdonnelly Theano

建议的版本。这是一个很好的坚实的环境设置-我真的推荐msys工具-我以前从未使用过它

Phillferrier指南中的测试脚本是测试功能/性能的好方法

2）然后我使用

pip安装pymc3

设置pymc3，正如他们在这里建议的那样。但不是git上的最新版本

希望有人觉得这个有用
