Question

我使用来自https://store.enthought.com/repo/.iron/的numpy，scipy egg包，它在ironpy 2.7.3中表现良好。在Window 7中。但是ironpython 2.7.5支持pip安装流程，所以我升级到这个版本但是可以在ironpython中导入numpy。

我发现消息如下：

导入numpy           Traceback（最近一次调用最后一次）：            文件＆＃34;＆＃34;，第1行，in            文件＆＃34; D：\ MyDoc \ Training_Course \ ISP \ IronPython-2.7.5 \ IronPython-2.7.5 \ lib \ site-           packages \ numpy__init __。py＆＃34;，第155行，in            文件＆＃34; D：\ MyDoc \ Training_Course \ ISP \ IronPython-2.7.5 \ IronPython-2.7.5 \ lib \ site-           packages \ numpy \ core__init __。py＆＃34;，第6行，in            文件＆＃34; D：\ MyDoc \ Training_Course \ ISP \ IronPython-2.7.5 \ IronPython-2.7.5 \ lib \ site-           packages \ numpy \ core \ multiarray.py＆＃34;，第7行，in           ImportError：没有名为NumpyDotNet的模块

所以我将IronPython-2.7.5 \ DLLs * .dll复制到IronPython-2.7.5文件夹并解决NumpyDotNet模块未找到的问题，但又出现了一个问题，我列出如下：

WRN: Assembly binding logging is turned OFF.
To enable assembly bind failure logging, set the registry value [HKLM\Software\M
icrosoft\Fusion!EnableLog] (DWORD) to 1.
Note: There is some performance penalty associated with assembly bind failure lo
gging.
To turn this feature off, remove the registry value [HKLM\Software\Microsoft\Fus
ion!EnableLog].

我曾经问过Enthought支持，他们的回应是没有计划再升级它。他们建议我在这个论坛上寻求可能的支持那么任何人都有解决我遇到的问题的解决方案吗？

提前感谢您。

已经过了几个月但是......

您需要按照错误消息

中的说明启用绑定失败日志记录

要启用程序集绑定失败日志记录，请设置注册表值 [HKLM \ Software \ M icrosoft \ Fusion！EnableLog]（DWORD）为1。

然后，您将能够看到程序集绑定失败的位置。就我而言，GAC中有一个发布者政策将IronPython版本重定向到我的系统上不存在的东西。如果是这样，您需要在配置文件中对其进行注释。

E.g。在policy.IronPython.config中（一旦您启用了程序集绑定失败日志记录，您就能够看到确切的文件位置），请像这样注释掉这两行：

#         <bindingRedirect oldVersion="2.7.0.40"
#                          newVersion="2.7.5.0"/>

希望它有所帮助。
