Question

我正在尝试使用pyximport，如下所示：

import pyximport; pyximport.install(pyimport=True,language_level=3)
from multiprocessing import Pool, Manager, cpu_count

当我尝试运行它时，出现以下错误消息：

Traceback (most recent call last):
  File "C:\Python\lib\site-packages\pyximport\pyximport.py", line 216, in load_module
    mod = imp.load_dynamic(name, so_path)
  File "C:\Python\lib\imp.py", line 342, in load_dynamic
    return _load(spec)
ImportError: DLL load failed: %1: not a valid Win32 application.

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "D:/Google drive/Python/Backtesting/backtesting_uj/scratch3.py", line 2, in <module>
    from multiprocessing import Pool, Manager, cpu_count
  File "C:\Python\lib\site-packages\pyximport\pyximport.py", line 423, in load_module
    return load_module(fullname, source_path, so_path=so_path, is_package=is_package)
  File "C:\Python\lib\site-packages\pyximport\pyximport.py", line 231, in load_module
    raise exc.with_traceback(tb)
  File "C:\Python\lib\site-packages\pyximport\pyximport.py", line 216, in load_module
    mod = imp.load_dynamic(name, so_path)
  File "C:\Python\lib\imp.py", line 342, in load_dynamic
    return _load(spec)
ImportError: Building module multiprocessing failed: ['ImportError: DLL load failed: %1: not a valid Win32 application.\n']

任何想法如何解决？我要使用的功能使用multiprocessing Manager dict。如果仅在导入函数之前放入“ import pyximport; pyximport.install（pyimport = True，language_level = 3）”，则会出现以下错误，因此，我认为必须对整个mulptiprocessing模糊进行cythonized处理。我不是python专家，我正在尝试尽可能加快我的代码的速度。

  File "C:\Python\lib\multiprocessing\context.py", line 322, in _Popen
    return Popen(process_obj)

  File "C:\Python\lib\multiprocessing\reduction.py", line 60, in dump
    ForkingPickler(file, protocol).dump(obj)
_pickle.PicklingError: Can't pickle <class 'importlib._bootstrap.DictProxy'>: attribute lookup DictProxy on importlib._bootstrap failed

带有多重处理的pyximport-> ImportError：DLL加载失败：％1：不是有效的Win32应用程序
