python - 导入错误: cannot import name 'LinearNDInterpolator'

Question

我已经用 Python 3.6.2 编写了一个程序，我试图使用 cx_Freeze 卡住该程序以进行分发。但是当我尝试运行生成的可执行文件时，我遇到了一个奇怪的错误(我的基本程序使用 pyLDAvis.sklearn)。错误重现如下:

Traceback (most recent call last):

ImportError: cannot import name 'LinearNDInterpolator'

我的 cx_freeze 脚本的可执行选项如下:

build_exe_options = {
                        "packages": ["os","textwrap","msvcrt","warnings","time","datetime","platform","sklearn","operator","nltk.tokenize","stop_words","pandas","nltk.stem.porter","sklearn.feature_extraction.text","sklearn.decomposition","progressbar","numpy","packaging","asyncio",
                        ], 

                        "includes": ["appdirs","packaging.version","packaging.specifiers","packaging.requirements","pyLDAvis.sklearn","pyLDAvis.urls","scipy.sparse.csgraph._validation"],

                        "excludes" : ["tkinter","sqlite3"],

                        "include_msvcr" : True
                    }

我似乎找不到 scipy.interpolate 或 scipy.interpolate.interpnd 的任何组合来放入让其工作的构建选项 - 我始终收到“无法导入名称'LinearNDInterpolator'”错误。重新安装 scipy 没有帮助。

有人可以建议吗？难道我注定无法卡住我的代码吗？

Answer 1

1. 您是否尝试过添加

   import scipy.interpolate.interpnd
   

   在你的基本程序中(而不是在安装脚本中)？然后会发生什么？

2. 根据我目前的经验，需要将scipy添加到packages列表中，才能让正确包含它>cx_Freeze。但随后还需要将 scipy.spatial.cKDTree 添加到排除列表中，因为 this issue 。因此，请尝试在设置脚本中使用以下选项:

   build_exe_options = {
                   "packages": ["os","textwrap","msvcrt","warnings","time","datetime","platform","sklearn","operator","nltk.tokenize","stop_words","pandas","nltk.stem.porter","sklearn.feature_extraction.text","sklearn.decomposition","progressbar","numpy","packaging","asyncio","scipy"
                   ], 
   
                   "includes": ["appdirs","packaging.version","packaging.specifiers","packaging.requirements","pyLDAvis.sklearn","pyLDAvis.urls","scipy.sparse.csgraph._validation"],
   
                   "excludes" : ["tkinter","sqlite3","scipy.spatial.cKDTree"],
   
                   "include_msvcr" : True
               }
   

3. 补充说明:build_exe 选项 "include_msvcr": True 似乎对 cx_Freeze 版本 5.0.2 没有影响， 5.1.1 和 6.0b1。请参阅this issue ，我在那里的帖子 (jpeg13) 包含更多详细信息。您可能需要使用 build_exe 选项 include_files 手动添加 MSVCR DLL。
