Scipy和Cython的AttributeError,同时使用cx_Freeze

标签: python scipy cython cx-freeze

我正在使用cx_Freeze将python脚本转换为exe文件。 不幸的是,创建该exe文件后,我得到了AttributeError

  

AttributeError:类型对象'scipy.interpolate.interpnd.array'没有   属性“ reduce_cython

使用的版本: 的Python:3.7.3 Scipy:1.2.1 Cython:0.29.7 cx_Freeze:5.1.1

我已经将所有使用的模块升级到最新版本,并搜索错误。我还尝试再次卸载并重新安装模块。

我使用了以下cx_Freeze setup.py

from cx_Freeze import setup, Executable
import os

# Set environment variables
# https://stackoverflow.com/questions/35533803/keyerror-tcl-library-when-i-use-cx-freeze
os.environ['TCL_LIBRARY'] = r'C:\Program Files (x86)\Microsoft Visual Studio\Shared\Anaconda3_64\tcl\tcl8.6'
os.environ['TK_LIBRARY'] = r'C:\Program Files (x86)\Microsoft Visual Studio\Shared\Anaconda3_64\tcl\tk8.6'

includes = ["numpy", "numpy.core._methods", "numpy.lib.format", "sklearn", "ipaddress", "schwifty", "pandas", "multiprocessing.pool", "pkg_resources._vendor", "appdirs", "sklearn.ensemble.forest", "packaging.version", "packaging.specifiers", "packaging.requirements", "xgboost", "email.mime.text", "email.mime.multipart", "idna.idnadata", 'scipy._distributor_init', 'scipy.sparse.csgraph._validation', "cython", "scipy.interpolate.interpnd", "scipy"]

setup(name = "fraudDetection",
      version = "0.1",
      description = "",
      options = {'build_exe': {'includes': includes}},
      executables = [Executable("fraudDetection.py")]
      )

我希望exe文件能够运行并给出预测(欺诈检测),但我收到此错误消息(每次启动exe文件时):

编辑:更新了错误文件

谢谢您的任何建议!

1 个答案:

答案 0 :(得分:0)

  1. 正如@ead和@DavidW所评论的那样,您发布的错误消息表明,鉴于路径中的Python36文件夹,Scipy是从Python 3.6安装中导入的。

    File "C:\Users\user.name\AppData\Roaming\Python\Python36\site-packages\scipy\interpolate\interpolate.py"
    

    但是也许您只是忘了编辑错误消息的这一部分。

    无论如何,您可以添加以下行

    import sys
    import scipy
    print(sys.version)
    print(scipy.__version__)
    

    访问setup.py文件,以查看cx_Freeze构建可执行文件时实际使用的是哪个版本的Python和Scipy。

  2. 在Cython github存储库中对相同的错误消息进行了广泛的讨论,请参见Issue #1953。您可能在那里找到更多建议。

    根据此讨论,该错误是由Cython中的一个问题引起的,该问题已在Cython 0.28中得以解决。您还可以在其中找到以下有用的comment

      

    [...]如果您安装的某个软件包是使用具有错误的旧Cython版本构建的,则仅在系统上安装Cython版本x.y完全无关紧要。

         

    由于原因固定为0.28,我现在将关闭这张票。如果您发现使用0.28或更高版本构建的软件中发生了类似的问题,请打开一张新票。

         

    编辑:要验证Cython实现的软件包是否使用正确的Cython版本构建,请解压缩其源代码分发包(来自PyPI的*.tar.gz),找到.c.cpp文件并查看其第一行。如果显示的是/* Generated by Cython 0.28 */或更高版本,则包含此修复程序。如果版本较旧,则不包含此修复程序,在这种情况下,最好向项目要求新版本。

    因此,您还需要检查所有使用Cython生成并包含在可执行文件中的软件包是否已使用Cython 0.28或更高版本进行了构建。
