【问题描述】：

我下载了 cntk 2.0 beta 7。在执行 .\install.ps1 时，出现 install.ps1 未进行数字签名的错误：

PS C:> cd .\local\cntk\Scripts\install\windows\ PS C:\local\cntk\Scripts\install\windows> .\install.ps1 .\install.ps1 : 文件 C:\local\cntk\Scripts\install\windows\install.ps1 无法加载。文件 C:\local\cntk\Scripts\install\windows\install.ps1 未进行数字签名。您不能在当前运行此脚本系统。有关运行脚本和设置执行策略的更多信息，请参阅 about_Execution_Policies，网址为 http://go.microsoft.com/fwlink/?LinkID=135170。在行：1 字符：1 + .\install.ps1 + ~~~~~~~~~~~~~ + CategoryInfo : SecurityError: (:) [], PSSecurityException + FullyQualifiedErrorId : UnauthorizedAccess

如果我启动 powershell -executionpolicy unrestricted install.ps1 能够运行但没有安装任何东西，这是输出：

This script will setup the CNTK prequisites and the CNTK Python environment onto the machine.
More help is given by calling 'get-help .\install.ps1' in your powershell environment.

The script will analyse your machine and will determine which components are required.
The required components will be downloaded in [C:\local\cntk\Scripts\install\windows\InstallCache]
Repeated operation of this script will reuse already downloaded components.

 - If required VS2012 Runtime and VS2013 Runtime will be installed
 - If required MSMPI will be installed
 - Anaconda3 will be installed into [C:\local\Anaconda3-4.1.1-Windows-x86_64]
 - A CNTK-PY34 environment will be created or updated in [C:\local\Anaconda3-4.1.1-Windows-x86_64\envs]
 - CNTK will be installed or updated in the CNTK-PY34 environment


The parameter '-Execute' hasn't be supplied to the script.
The script will execute withouth making any actual changes to the machine.

【解决方案1】：

请阅读 wiki 上的输出或文档！

“参数'-Execute'尚未提供给脚本。脚本将在不对机器进行任何实际更改的情况下执行”

以.\install.ps1 -Execute 运行脚本

【解决方案2】：

我遇到了同样的错误，我使用 Microsoft 的签名工具对文件进行了数字签名。签名后，此错误消失了。

“SignTool 作为 Windows SDK 的一部分提供......”

【解决方案3】：

Set-ExecutionPolicy -Scope Process -ExecutionPolicy Bypass

只需运行此命令试试这个简单的解决方法！
