OKUA1/juvio: UV kernel for Jupyter

• 💡 Inline Dependency Management

  Install packages right from the notebook:

  %juvio install numpy pandas

  Dependencies are saved directly in the notebook as metadata (PEP 723-style), like:

  # /// script
  # requires-python = "==3.10.17"
  # dependencies = [
  # "numpy==2.2.5",
  # "pandas==2.2.3"
  # ]
  # ///

• ⚙️ Automatic Environment Setup

  When the notebook is opened, Juvio installs the dependencies automatically in an ephemeral virtual environment (using uv), ensuring that the notebook runs with the correct versions of the packages and Python.

• 📁 Git-Friendly Format

  Notebooks are converted on the fly to a script-style format using # %% markers, making diffs and version control painless:

  # %%
  %juvio install numpy
  # %%
  import numpy as np
  # %%
  arr = np.array([1, 2, 3])
  print(arr)
  # %%

1. Install Juvio:

pip install juvio
jupyter labextension enable juvio-frontend

2. Make sure you have uv installed:
