Question

我在Windows 7 64位上运行Anaconda 4.3.1（Python 3.6.1）并且无法将theano和openturns导入到我的会话中，但是只导入一个或其他工作正常。显然，一方在另一方引起某种导入冲突，但我不了解导入过程以确定原因。

如果theano被导入并且我尝试导入openturns，我得到了这个：

import theano.tensor as tt
import openturns as ot

    Traceback (most recent call last):

      File "<ipython-input-38-704e69d30dff>", line 1, in <module>
        import openturns as ot

      File "C:\Anaconda3\lib\site-packages\openturns\__init__.py", line 61, in <module>
        from .common import *

      File "C:\Anaconda3\lib\site-packages\openturns\common.py", line 20, in <module>
        _common = swig_import_helper()

      File "C:\Anaconda3\lib\site-packages\openturns\common.py", line 19, in swig_import_helper
        return importlib.import_module('_common')

      File "C:\Anaconda3\lib\importlib\__init__.py", line 126, in import_module
        return _bootstrap._gcd_import(name[level:], package, level)

    ModuleNotFoundError: No module named '_common'

如果我尝试反过来，导入openturns然后我尝试导入theano，我明白了：

import openturns as ot    
from theano import tensor as tt
Traceback (most recent call last):

  File "<ipython-input-3-ed4283f52c57>", line 1, in <module>
    from theano import tensor as tt

  File "C:\Anaconda3\lib\site-packages\theano\__init__.py", line 80, in <module>
    from theano.scan_module import (scan, map, reduce, foldl, foldr, clone,

  File "C:\Anaconda3\lib\site-packages\theano\scan_module\__init__.py", line 41, in <module>
    from theano.scan_module import scan_opt

  File "C:\Anaconda3\lib\site-packages\theano\scan_module\scan_opt.py", line 60, in <module>
    from theano import tensor, scalar

  File "C:\Anaconda3\lib\site-packages\theano\tensor\__init__.py", line 9, in <module>
    from theano.tensor.subtensor import *

  File "C:\Anaconda3\lib\site-packages\theano\tensor\subtensor.py", line 26, in <module>
    import theano.gof.cutils  # needed to import cutils_ext

  File "C:\Anaconda3\lib\site-packages\theano\gof\cutils.py", line 320, in <module>
    compile_cutils()

  File "C:\Anaconda3\lib\site-packages\theano\gof\cutils.py", line 285, in compile_cutils
    preargs=args)

  File "C:\Anaconda3\lib\site-packages\theano\gof\cmodule.py", line 2325, in compile_str
    return dlimport(lib_filename)

  File "C:\Anaconda3\lib\site-packages\theano\gof\cmodule.py", line 302, in dlimport
    rval = __import__(module_name, {}, {}, [module_name])

ImportError: DLL load failed: The specified procedure could not be found.

不确定是否相关，但Theano安装要求我将包含一些DLL的文件夹添加到系统PATH。谢谢！

Answer 1

似乎来自默认的anaconda频道的theano软件包提取了mingw依赖项，这可能与我们自己的新提供的运行时冲突;解决方法是从conda-forge安装所有内容。

这应该有效：

conda install openturns theano pymc3 -c conda-forge

Python包导入冲突（Theano和openturns）
