我的目标是在 Mac OS 10.10.5 上安装 PyMC3 和 Python3。我的以下方法失败了:

  1. 我查看了 Theano 网站,发现尚不支持 Python 3.6。
  2. 所以我选择了 Python 3.5,使用 https://repo.continuum.io/archive/Anaconda3-4.2.0-MacOSX-x86_64.pkg (遵循 docs.continuum.io/anaconda/faq.html#anaconda-faq-35)
  3. 在 Jupiter QtConsole 中,我运行了 !conda install -y -c conda-forge pymc3(修改了 pymc-devs.github.io/pymc3/中推荐的命令)
  4. 安装成功
  5. 导入 pymc3 失败,“找不到‘stdio.h’文件”
  6. 我运行了 !xcode-select --install(按照 stackoverflow.com/a/40301452 的建议)
  7. import pymc3 再次失败,现在出现以下错误消息:

异常:编译失败(返回状态=1):ld:找不到符号dyld_stub_binding_helper,通常在crt1.o/dylib1.o/bundle1.o for architecture x86_64。 clang:错误:链接器命令失败,退出代码为 1(使用 -v 查看调用)。

这是错误消息的较长尾部:

如何继续安装 PyMC3?

最佳答案

有点晚了,但希望这对其他人有帮助。

我刚刚遇到了和你一样的问题,我花了一个小时寻找解决方案。事实证明,将 MacOS 更新到 High Sierra 后问题出现在我身上;解决方法是重新安装 XCode 命令行工具。

因此,完全适合我的步骤(可能最好在终端而不是 Jupyter Qt 控制台中运行):

  1. xcode-select --install
  2. conda create -n pymc3 python=3.6
  3. 源码激活pymc3
  4. conda install -c conda-forge pymc3

我很欣赏我的回答更多是对其他回答的总结,但希望能增加更多背景信息。
