[FIXED] Fail to setup octave magic commands on Google Colab: module 'oct2py' has no attribute 'octave'

Issue

I am trying to draft a MATLAB/Octave tutorial on Google Colab, and was hoping to use magic commands %octave and %%octave to write most of the cells. However, when I tried to setup the environment using the below commands

!apt-get install octave
!pip install oct2py
%load_ext oct2py.ipython

I got an error AttributeError: module 'oct2py' has no attribute 'octave' for the %load_ext command above, here is the full error log:

AttributeError                            Traceback (most recent call last)

      2 get_ipython().system('pip install oct2py')

AttributeError: module 'oct2py' has no attribute 'octave'

I am wondering if this is a known issue, and if there is any workaround.

Solution

As @OriYarden noted in a previous reply - the commands in fact worked fine. The previous issue I had may just be a glitch due to incomplete installation.

Again, these 3 commands do work (takes 4-5 min to complete) to make Google Colab to support Octave magic commands

!apt-get install octave
!pip install oct2py
%load_ext oct2py.ipython
