I am using oct2py to call a octave function in my python code. The file is saved as .py file in the htdocs folder.

#!/usr/bin/python
import cgi
import oct2py
from oct2py import octave
print('Content-type:text/html\r\n\r\n')
print('<!DOCTYPE html>')
firnum='23'
secnum='33'
octave.addpath('/Applications/XAMPP/xamppfiles/htdocs/mypython/Octavemfiles/')
firnum=int(firnum)
secnum=int(secnum)
answer=octave.mymultfunct(firnum,secnum)
print(answer)

The code works well when executing from the terminal and gives the answer. But when I call it through the web, the oct2py gives an error stating 

OSError: Octave Executable not found, please add to path or set"OCTAVE_EXECUTABLE" environment.

Please suggest a way out so I can call the function from octave. The octave function is just multiplying the numbers.

    The error message tells you two possible ways to solve the problem. Have you tried any of them? – ForceBru Nov 20 '16 at 16:41
  • The webserver presumably does not run with the same environmental variables initialised as your local terminal. If you are unable to define OCTAVE_EXECUTABLE at the point of launching the webserver, perhaps you will be able to define it within python before importing oct2py itself (see: http://stackoverflow.com/questions/5971312/how-to-set-environment-variables-in-python for an example of setting environment variables from within python) – Tasos Papastylianou Nov 20 '16 at 20:10
  • I am new to this, how do I add path for Octave. The program doesn't execute the line ' from oct2py import octave'. Thanks – amathur Nov 21 '16 at 11:04
  • @amathur have you tried importing via python as I said above? it would look something like `os.environ["OCTAVE_EXECUTABLE"] = "/path/to/your/octave/executable"` (assuming that your webserver has permission to access that path) – Tasos Papastylianou Nov 22 '16 at 12:30
  • Is the package 'oct2py' installed in your runtime enviroment? (From the webserver) – Nils Aug 14 '17 at 13:51

In Linux distribution: command : sudo pip install oct2py Error:

Solution Please install octave using : command : sudo apt-get install octave
