compile error about function declare

[hyer]

When I compiled the project, I got errors:

pytorch.cpp:356:63: error: ‘THNN_Threshold_updateOutput’ was not declared in this scope
THNN_Threshold_updateOutput(input, input, 0, 0, true) ;
...

I have installed ATen.
Any help?

Hi @hyer , Did you install our fork of ATen ?

And please provide more info about your system: ubuntu?, cuda 8? and so on 😃

[hyer]

@warmspringwinds Sorry.
My machine: Ubuntu14.04, CUDA8.0.

Here are my cmake results:

I have clone the ATen with: git clone --recursive https://github.com/warmspringwinds/pytorch-cpp
The ATen and HDF were builded successlly. When Make pytorch-cpp, got errors:

@hyer Thank you.

Could you try running this in bash pip install pyyaml ?

[warmspringwinds]

@hyer and install and build from scratch

[hyer]

@warmspringwinds I have installed pyyaml. It didn't make any difference. I think there may be sth wrong with the CMakeLists.txt or the build process.
