In the attached file JupyterLab,  
Notebook (.ipynb) is made for Python (.py).

On JupyterLab like above,  
I would like to be able to make Notebook(.ipynb) for Scilab(.sce)  
If possible, I would like to be able to use Xcos (.zcos) on JupyterLab.  
 → Please tell me how to do the above.

Hello,

There is an (unsupported) experimental Scilab Jupyter kernel there:

Mr. mottelet,

Nice to meet you, my name is protfor.

Thank you for your prompt reply.

I will try it from today!

Dear

-I am targeting Ubuntu 22.04lts.  
-As a result of installing scilab\_kernel, I was able to select Scilab from Python from the column as shown below.  
-But it doesn’t work even if it’s about 1+1 calculation…

→ Please tell me how to solve it (eg. change from 22.04lts to 20.04lts etc.)

Hello mottelet,

Set the Scilab PATH is the solution. **But if I run my Scilab Code in Jupyter Notebook, it is launching the Scilab Application and does not execute the command in Jupyter notebook.**

SCILAB\_EXECUTABLE is set. I used setx in the Windows CMD, because I do not have ADMIN rights

> setx SCILAB\_EXECUTABLE C:/Scilex.exe  
> setx PATH “%SCILAB\_EXECUTABLE%;%PATH%”

Following test worked: It seems to be that I have some trouble with python.

> python -m scilab\_kernel.check

Dear mottelet,

I’m protocol.

In my case, I simply didn’t have scilab itself installed.

Based on the URL below  
[Install Scilab on Ubuntu](https://linuxhint.com/install-scilab-on-ubuntu/)  
$sudo apt install scilab  
did.

As a result of installing scilab, as shown below  
scilab works on jupyter!

The Question is,

which SCILAB\_EXECUTABLE

I am not **able to create a plot**

Dear

Premise:  
Environment is Ubuntu 22.04lts, Scilab is installed, and Scilab\_kernel is installed!

Question:  
I’m trying to plot a bode plot in the control domain as shown below, but the problem is that the lines are not drawn on the bode plot;;  
 → Please tell me how to solve it, such as adding a package!!

I do not have ADMIN rights on my Windows machine.

How did you set the SCILAB\_EXECUTABLE environment variable?

I tried

> setx SCILAB\_EXECUTABLE “%SCILAB\_EXECUTABLE%;C:\Tools\scilab-2023.1.0\bin\Scilex.exe -nwni”

but this is not the right syntax

The only way I get Jupyter Notebook working with Scilab Kernel is

> setx SCILAB\_EXECUTABLE C:\Tools\scilab-2023.1.0\bin\Scilex.exe

I still have trouble to create any kind of Plot

I believe it is not woking, because the are limitation in my user rights on the PC. In case i figure out, what is the issue, i let you know.

It worked perfectly on my home pc.

```
python-installer.exe
pip install scilab_kernel
pip install jupyter
set SCILAB_EXECUTABLE WScilex-cli.exe
set PATH=%PATH%;%PROGRAMFILES%\scilab-2023.1.0\bin\

Python functions seamlessly in Jupyter Notebook, while Scilab encounters an issue. The evaluation process appears to be perpetually ongoing, as indicated by the persistent black circle cursor. No error messages are displayed in the Windows 10 x64 command window.

I followed the installation instructions meticulously through the command line. Interestingly, my colleague is not experiencing any problems, while I am unable to execute cell evaluations in Jupyter using the Scilab kernel.

I’m hopeful that someone can provide assistance in resolving this matter.

Here is the sequence of steps I undertook for installation:

1. Installed Scilab using scilab-2023.1.0.bin.x64.exe
2. Installed Python using python-installer.exe
3. Installed Jupyter using “pip install jupyter”
4. Installed the Scilab kernel for Jupyter using “pip install scilab\_kernel”
5. Set the SCILAB\_EXECUTABLE using “setx SCILAB\_EXECUTABLE WScilex-cli.exe”
6. Appended the Scilab binary directory to the PATH using the following commands:

- “setx PATH %PATH%;%PROGRAMFILES%\scilab-2023.1.0\bin”
- “setx PATH %PATH%;SCILAB\_EXECUTABLE”

Troubleshooting steps undertaken:

- Checked the Scilab kernel using “python -m scilab\_kernel.check”
- Verified the list of installed kernels using “jupyter kernelspec list”

Versions and outputs:

- Jupyter version: 1.0.0
- Scilab kernel version: 0.9.10
- Python version: 3.10.11

Output of “python -m scilab\_kernel.check”:

Scilab kernel version: 0.9.10 Metakernel version: 0.29.5 Python version: 3.10.11 (tags/v3.10.11:7d4cc5a, Apr 5 2023, 00:38:17) [MSC v.1929 64 bit (AMD64)] Python path: C:\Users\kwas\AppData\Local\Programs\Python\Python310\python.exe

Hello,

I have tried to install all required stuff from scratch on a fresh and non-admin “avuser” user account on a Windows 10 Pro (21H2) machine. Here is what it did, without having to get admin rights at anytime:

1. install Scilab 2023.1.0 in default path
2. install python for windows ([https://www.python.org/ftp/python/3.11.5/python-3.11.5-amd64.exe](https://www.python.org/ftp/python/3.11.5/python-3.11.5-amd64.exe)) and check “add Python to path” during installation
3. pip install jupyter (on cmd command line)
4. pip install scilab\_kernel (on cmd command line)
5. Add Scilab `bin` folder to Path user environment variable (on cmd command line)

```auto
setx Path "%Path%;C:\Users\avuser\AppData\Local\scilab-2023.1.0\bin"

```

Note: the `SCILAB_EXECUTABLE` environment variable seems useless in the current version of the Scilab kernel.

1. logout/login the Windows session.

I was then able to launch a notebook (on cmd command line) with:

```auto
python -m notebook

```

The notebook started with the default Python kernel, I then choosed ‘Scilab’ from the kernel menu, and typed in the first cell

```auto
plot

```

followed by Ctrl + Enter, I obtained the following:

Xcos has a dedicated GUI and Scilab GUI’s are not integrated in Jupyter. The Scilab kernel works as an engine taking its input from Jupyter cells and yielding text on the standard output and eventually graphics, which are also integrated in the html rendering of the notebook.
