1. Setup Python and JupyterLab

If you're on Windows 11, open the Terminal app; if you're still running Windows 10, open Windows PowerShell.

Install uv with

powershell -ExecutionPolicy ByPass -c "irm https://astral.sh/uv/install.ps1 | iex"

Next, make uv to play nice with SYSTRA firewall and point it to download packages from our repository

setx UV_NATIVE_TLS true

Then restart the terminal.

Move to a directory of you liking, then create the jupyterlab python environment with

uv init --python 3.12
uv add jupyterlab jupyter-lsp jupyterlab-lsp python-lsp-server[all]

NOTE: as of today (2025-05-21) ifcopenshell doesn't support versions newer than 3.12, this is why we added --python 3.12 option to uv init

verify it is working with

uv run jupyter-lab

NOTE: every time you want to start jupyter lab, you need to be in the same directory! But we can create a shortcut to always start jupyter the right way… Paste the following code in the terminal (you might need to stop jupyterlab to reuse the terminal above)

$workingDir = (Get-Item .).FullName
$shell = New-Object -ComObject WScript.Shell
$shortcut = $shell.CreateShortcut("$env:APPDATA\Microsoft\Windows\Start Menu\Programs\JupyterLab.lnk")
$shortcut.TargetPath = "$env:USERPROFILE\.local\bin\uv.exe"
$shortcut.Arguments = 'run jupyter-lab'
$shortcut.WorkingDirectory = $workingDir
$shortcut.IconLocation = "$workingDir\.venv\Lib\site-packages\jupyter_server\static\favicon.ico"
$shortcut.Save()
[System.Runtime.Interopservices.Marshal]::ReleaseComObject($shell)

If you don't trust the script, here's how to do it manually:

• Right click on your desktop -> New Shortcut ![[jupyter-shortcut-1.png]]
• In the input box, type uv and click Next or press enter ![[jupyter-shortcut-2.png]]
• Give it a name of you liking and click Finish or press enter ![[jupyter-shortcut-3.png]]
• right click on the shortcut and select Properties ![[jupyter-shortcut-4.png]]
• in Target, add run jupyter-lab at the end of the existing text
• in Start in, paste the full path of the directory you initialized above
• If you want, you can change the icon here ![[jupyter-shortcut-5.png]]

2. Installing packages with uv inside jupyter or from PS

To install new packages/libraries, run a cell with the !uv add and the package names, for example:

!uv add pandas openpyxl

these will be installed and also added to the pyproject.toml file, so that you can re-create the python/jupyterlab environment on another computer

TIP: You can also run the uv add command (without the leading !) inside a terminal, provided you're in the directory of the environment

NOTE: you can install packages from the systra repository if you have a gitlab.com account, create a personal access token and ask to be added to the swsengineering group. you need to set the UV_INDEX_URL environment variable:

setx UV_INDEX_URL https://__token__:<YOUR_TOKEN_HERE>@gitlab.com/api/v4/groups/9596324/-/packages/pypi/simple

code completion

• go to Settings -> Settings Editor (or press ++ctrl+,++)
• in the Search settings… box type completion
• Under one of the Code Completion sections select Enable autocompletion and in the other select Continuous hinting

3. Develop configuration

While was cloned repository pyfrc with:

$ git clone https://gitlab.com/luigi_paone/pyfrc.git

Go to jupyter folder created with

$ uv add <where is your pyfrc root folder>
