I have installed miniconda python version 3.6.1. conda,python,oct2py and all dependencies packages are up to date.

Both python and octave are installed using 64 bit windows binary installers.

In python script

I only use

from oct2py import octave

and I get the following error trackback:

Traceback (most recent call last):
File "C:/Users/t-avben/PycharmProjects/TailGrpDelayAnalysis/main.py", line 7, in <module>

startupinfo)
PermissionError: [WinError 5] Access is denied

I changed the octave binary folder permissions to full access for all users, and disabled windows UAC.

any suggestions?

EDIT:
I have set the octave environemnt variable to octave.exe.
Now I have another weird error message:

Traceback (most recent call last):

During handling of the above exception, another exception occurred:

  • `C:\Program Files\Python36\` is a weird location for anaconda install. Did you explicitly install it there or did you install python 3.6 separately? – Nehal J Wani Mar 30 '17 at 02:24

    @NehalJWani I installed python 3.6 separately. I solved the issue by canceling the read-only flag from octave vbase dir and explicitly setting OCTAVE_EXECUTABLE ENV to octave-cli.exe – vintox Mar 30 '17 at 14:19
