ImportError: cannot import name 'LinearNDInterpolator'

Question

我在 Python 3.6.2 中编写了一个程序，我试图使用 cx_Freeze 冻结分发。但是我在尝试运行生成的可执行文件时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
                    }

我似乎无法找到 scipy.interpolate 或 scipy.interpolate.interpnd 的任何组合来放入构建选项以使其工作 - 我一直收到 "can't import name 'LinearNDInterpolator'" 错误.重新安装 scipy 没有帮助。

有人可以指教吗？我只是注定无法冻结我的代码吗？

Answer 1

你试过添加
```
import scipy.interpolate.interpnd
```
在你的基础程序中（不在安装脚本中）？那会发生什么？

根据我目前的经验，需要将scipy添加到packages列表中才能使其被[=14=正确包含].但是由于 this issue，还需要将 scipy.spatial.cKDTree 添加到 excludes 列表中。因此，请尝试在安装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
            }

补充说明：build_exe 选项 "include_msvcr": True 似乎对 cx_Freeze 版本 5.0.2、5.1.1 和 6.0b1 没有影响。请参阅 this issue，我的 post 那里 (jpeg13) 包含更多详细信息。您可能需要使用 build_exe 选项 include_files.
