如何在IronPython2.7.5中支持numpy、scipy

Question

我使用了来自https://store.enthought.com/repo/.iron/的numpy，scipyegg包，它在IronPython2.7.3中表现良好。在7号窗口。 但是IronPython2.7.5支持pip安装流，所以我升级到这个版本，但是在ironpython中导入numpy是可以的。在

我发现以下信息：

import numpy Traceback (most recent call last): File "", line 1, in File "D:\MyDoc\Training_Course\ISP\IronPython-2.7.5\IronPython-2.7.5\lib\site- packages\numpy__init__.py", line 155, in File "D:\MyDoc\Training_Course\ISP\IronPython-2.7.5\IronPython-2.7.5\lib\site- packages\numpy\core__init__.py", line 6, in File "D:\MyDoc\Training_Course\ISP\IronPython-2.7.5\IronPython-2.7.5\lib\site- packages\numpy\core\multiarray.py", line 7, in ImportError: No module named NumpyDotNet

因此，我将IronPython-2.7.5\DLLs*.dll复制到IronPython-2.7.5文件夹，并解决NumpyDotNet模块找不到问题，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].

我曾经请求过热情的支持，但他们的反应是不再计划升级。他们建议我在这个论坛寻求可能的支持 那么有谁能找到解决我遇到的问题的方法吗？在

提前谢谢你。在

已经几个月了，但是。。。在

您需要启用绑定失败日志记录，如错误消息中所述

To enable assembly bind failure logging, set the registry value [HKLM\Software\M icrosoft\Fusion!EnableLog] (DWORD) to 1.

然后您将能够看到程序集绑定失败的地方。在我的例子中，GAC中有一个发布者策略，它将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注释掉它。在

例如，在policy.IronPython.config（一旦启用了程序集绑定失败日志记录，您将能够看到确切的文件位置），将这两行注释掉，如下所示：

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

希望有帮助。在
