Octave_kernel on Juypyter MacOs

[bitMaestro]

Greetings, I'm attempting to get Octave up and running on Jupyter Notebook. I see the kernel in the drop down menu but then I have an error message:

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

I've tried all the suggestions and I usually find a solution before relying on help but this time its been about 5 hours and still in trouble. Can you please walk me through this because I'm having technical difficulties.

Thank you in advance. Tarique

Hi @bitMaestro, if you start a notebook with python kernel and type the following, what is the output?

!which octave; echo $OCTAVE_EXECUTABLE

[bitMaestro]

Hi, I cannot run,

!which octave; echo $OCTAVE_EXECUTABLE

directly from within Jupyter notebook. I receive an error message, pease see error message from terminal.

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

However running the code in the terminal give me this:

which python octave; echo $OCTAVE_EXECUTABLE octave; echo $OCTAVE_EXECUTABLE

Are you able to start a notebook with a Python kernel? The above command is intended for a Python kernel.

[bitMaestro]

Yes. If I select Python from the drop down inside of Jupyter notebook Python will run as it should.

After starting the Python notebook, what is the output of running a cell with the following? !which octave; echo $OCTAVE_EXECUTABLE?

[ghost]

I have same problem !which octave; echo $OCTAVE_EXECUTABLE? The output of running a cell is Object OCTAVE_EXECUTABLE not found.

@ksk8863 Did you set such a variable in the shell before running Jupyter? You need to do something like:

export OCTAVE_EXECUTABLE=$(which octave)

[asavasci]

hello, I am using macos, my octave installation is up and running but I cannot use jupyter notebook. When I attempt to create an octave notebook I am getting error below OSError: Octave Executable not found, please add to path or set"OCTAVE_EXECUTABLE" environment variable

I set an environment variable as export PATH="/Applications/Octave.app/Contents/Resources/usr/Cellar/octave-octave-app_4.4.0/4.4.0/bin/octave-cli:$PATH"

into the bash_profile. However, it seems not working.

Could you advise me how to solve this issue?

[dsblank]

Don't put the executable in the path (remove octave-cli)

[asavasci]

I tried but getting same error. Should I use different command to set an environment variable?

[blink1073]

@asavasci, are you able to run octave-cli from a terminal after setting up your PATH as above?

[rucarden]

When I installed octave 4.4 using the app bundle at https://wiki.octave.org/Octave_for_macOS, it didn't come with an octave-cli only an octave command. I just made a link with that name and put in my home bin directory which is in my path. ln -s /usr/local/bin/octave ~/bin/octave-cli
