mac 上的 CPLEX Python API 问题

Question

我已经阅读了很多关于问题的帖子，但其中 none 可以解决我的问题。尽管我一直在关注 this blog，但当我尝试运行示例 src python 文件之一时，我仍然会遇到此错误：

Traceback (most recent call last):
  File "facility.py", line 25, in <module>
    import cplex
  File "/Users/sb/Applications/IBM/ILOG/CPLEX_Studio1251/cplex/python/x86_darwin/cplex/__init__.py", line 43, in <module>

   from cplex._internal.py1013_cplex1251 import *
  ImportError: dlopen(/Users/sb/Applications/IBM/ILOG/CPLEX_Studio1251/cplex/python/x86_darwin/cplex/_internal/py1013_cplex1251.so, 2): no suitable image found.  Did find:
    /Users/sb/Applications/IBM/ILOG/CPLEX_Studio1251/cplex/python/x86_darwin/cplex/_internal/py1013_cplex1251.so: mach-o, but wrong architecture

不幸的是我不熟悉 /.bash_profile 但是我在最后添加的 link 中发布了什么。有人可以帮我吗？

一个可能的解决方案是检查您是否可以手动将 cplex 目录复制到已安装的站点包中（您可能需要使用 sudo）。

从你的堆栈跟踪中我看到你已经安装了 cplex /Users/sb/Applications/IBM/ILOG/CPLEX_Studio1251/cplex/python/x86_darwin/

首先运行（我假设你python2.7）在互动shell:

import site; site.getsitepackages()

有关此步骤的详细信息，请参阅 How do I find the location of my Python site-packages directory?。

这将为您提供需要将 "cplex" 目录复制到的站点包目录。我假设它是 /Library/Python/2.7/site-packages from here

在 mac 然后运行:

sudo cp -r ./cplex /Library/Python/2.7/site-packages/

这会将 cplex 手动设置为 python 安装的可导入包。因此，您应该能够在 python 交互式 shell 中导入 cplex。
