我在尝试导入使用 swig 的 python 库时遇到“错误的 ELF class”错误

Question

我一直在尝试导入一个名为 dwave tabu 的 python 库，它使用 swig，但我遇到了一些问题。在 python3 中导入包时，我得到了这个结果：

    >>>import tabu
    Traceback (most recent call last):
    File "/home/chip/.local/lib/python3.5/site-  packages/tabu/tabu_search.py", line 14, in swig_import_helper
    return importlib.import_module(mname)
    File "/usr/lib/python3.5/importlib/__init__.py", line 126, in import_module
    return _bootstrap._gcd_import(name[level:], package, level)
    File "<frozen importlib._bootstrap>", line 986, in _gcd_import
    File "<frozen importlib._bootstrap>", line 969, in   _find_and_load
    File "<frozen importlib._bootstrap>", line 958, in _find_and_load_unlocked
    File "<frozen importlib._bootstrap>", line 666, in _load_unlocked
    File "<frozen importlib._bootstrap>", line 577, in module_from_spec
    File "<frozen importlib._bootstrap_external>", line 914, in create_module
   File "<frozen importlib._bootstrap>", line 222, in _call_with_frames_removed
   ImportError: /home/chip/.local/lib/python3.5/site-packages/tabu/_tabu_search.so: wrong ELF class: ELFCLASS64
   During handling of the above exception, another exception occurred:
   Traceback (most recent call last):
   File "<stdin>", line 1, in <module>
   File "/home/chip/.local/lib/python3.5/site-packages/tabu/__init__.py", line 17, in <module>
   from tabu.tabu_search import TabuSearch
   File "/home/chip/.local/lib/python3.5/site-  packages/tabu/tabu_search.py", line 17, in <module>
   _tabu_search = swig_import_helper()
   File "/home/chip/.local/lib/python3.5/site-packages/tabu/tabu_search.py", line 16, in swig_import_helper
   return importlib.import_module('_tabu_search')
   File "/usr/lib/python3.5/importlib/__init__.py", line 126, in   import_module
   return _bootstrap._gcd_import(name[level:], package, level)
   ImportError: No module named '_tabu_search'

我怀疑错误与swig有关，但我不确定如何解决它。另外，在 32 位安装上，似乎是针对 64 位 linux 编译的二进制文件引起的错误，但我不知道如何解决该问题。任何帮助将不胜感激。谢谢

ImportError: /home/chip/.local/lib/python3.5/site-packages/tabu/_tabu_search.so: wrong ELF class: ELFCLASS64

此错误表示：您正在尝试将 64 位 _tabu_search.so 库加载到 32 位进程中。您必须使用 64 位 python，或者安装 32 位版本的 tabu_search 软件包。

I suspect that the error has something to do with swig

不，SWIG与您的问题几乎无关。
