When installing oct2py library on Python, I was required to have GNU Octave installed in my path, in another word, setx PATH "%PATH%; where the folder has the file “octave.exe”.
However, I can not find the octave.exe after installing octave using the installation packages released in https://www.gnu.org/software/octave/#install and I have tried all the three installation packages for Windows-64.
Thanks for your help!
