Symbol lookup error #1446

Closed xiaoshingshing closed 7 years ago

xiaoshingshing commented 7 years ago

I encounter the following error when running cntk:

cntk: symbol lookup error: cntk: undefined symbol: _ZNK9Microsoft3MSR4CNTK6MatrixIfE8GetIndexEv

What is the problem?

wilrich-msft commented 7 years ago

You can unmangle the symbol as follows:

c:\>c++filt _ZNK9Microsoft3MSR4CNTK6MatrixIfE8GetIndexEv

Microsoft::MSR::CNTK::Matrix<float>::GetIndex() const

So it seems something went wrong in your compilation/linking process. Can you share more on how you installed CNTK and where this error occurred?

The problem is solved. CNTK v2 Python support needs to be installed.
