Error Installing Microsoft CNTK - cntk

Question

During installation I received the following error:
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\Scripts\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
If required the standard Git tool will be installed
CNTK source will be cloned from Git into [c:\repos\CNTK]
Anaconda3 will be installed into [C:\local\Anaconda3-4.1.1-Windows-x86_64]
A CNTK-PY34 environment will be created in [C:\local\Anaconda3-4.1.1-Windows-x86_64\envs]
CNTK will be installed into the CNTK-PY34 environment

I'm not familiar with powershell, so I am not sure where to go from here.

Answer 1

Couple of questions. Are you using beta1 or beta2?
If you are using beta1, just a reminder that there is a beta2 now available with bug fixes and also some improvements to the install script, but I don't think this particular problem has been addressed!
It looks like the clone of the cntk git repository is failing.
Was Git installed on your machine? Is there a GIT.EXE in c:\Program Files\Git\bin\?
I think the install found an existing git.exe (in a different location), and is now trying to call it at the 'wrong' location.
The easiest workaround for you (if you have git installed), from a command prompt:
cd c:/
md \repos
cd repos
clone --branch v2.0.beta1.0 --recursive https://github.com/Microsoft/CNTK
If you have moved to beta2, replace the v2.0.beta1.0 with v2.0.beta2.0
