Can not find 
I create a pytorch extention, followed by this link
but it throws out the error that 


  fatal error: torch/extension.h: No such file or directory.


ubuntu 18.04
code::blocks 17.04
gcc 7.4.0


#include &lt;torch/extension.h&gt;


I expect the code to run.
Is there any document to fix this problem?

 is the canonical header file that create Python bindings for C++/Cuda extensions. 
So Try upgrading the version of Pytorch if it's not in newest version.
