python - CNTK(微软认知工具包)导入错误

代码:

import cntk
n = cntk.minus([1, 2, 3], [4, 5, 6]).eval()
print(n)

问题:

Traceback (most recent call last):
File "D:\Apps\Anaconda3\envs\Python3.53\lib\site-packages\cntk\cntk_py.py", line 18, in swig_import_helper
  return importlib.import_module(mname)

ImportError: No module named 'cntk._cntk_py'

During handling of the above exception, another exception occurred:

    return _bootstrap._gcd_import(name[level:], package, level)
ImportError: DLL load failed: The specified module could not be found.

环境:

python :4.3.1

Python:3.5.3(anaconda 中的虚拟环境)

CNTK:2.0beta12 for windows amd64 GPU

PyCharm:2016.3.2

Visual Studio 代码:1.10.2

最佳答案

解决了

因为找不到带有CNTK的DLL文件(例如CNTKLibrary-2.0.dll、EvalDll.dll)，所以安装CNTK后这些DLL都在“python.exe”的同一目录下。

有2种解决方案:

(假设PYTHONDIR是python.exe所在的目录)

更改系统环境路径以包含 PYTHONDIR

在“import cntk”前添加如下代码:

导入操作系统； os.environ['PATH'] = PYTHONDIR + ';' + os.environ['PATH']
