SimpleDemo output equal values

Aug 27, 2015 at 11:56 AM
Hello, my name is Alex,
I've compiled cntk successfully and use cpu only version. (Windows)
I've ran SimpleDemo (without models folder) and in console CNTK tells me that training completed, as an output i get file SimpleOutput.ScaledLogLikelihood, but it contains only:
0.519422 0.767147
0.519422 0.767147
0.519422 0.767147
What i'm doing wrong?
Please, I really need help.

Thank you.
Best Regards,

WOW, I downloaded binary version and it works!
I don't know what is the problem with the compiled from source version, it compiles, i have all libs installed, strange,
Please help.

it might because of the ACML library. We have noticed that on some intel CPU chips the results generated by this library is incorrect. In the compiled version we used Intel's MKL.

You are right, thank you very much, i installed Intel MKL before i started binary version (as recommended in Downloads).
Also, now you can change yours recommendations in installing ACML first, because starting from August 25, 2015 Intel made available whole Intel Parallel Toolkit as Community release, free without any restrictions.
Thank you again, closing this thread.

Can you please point to us the announcement you mentioned regarding MKL? We cannot seem to find it.
