Atoti Python SDK requires one of the following Python versions:

• 3.10
• 3.11
• 3.12
• 3.13

In addition, Atoti Python SDK requires Java 21 if you want to use your own JDK. If you do not have a JDK, Atoti is bundled with jdk4py. We use uv for better virtual environment and dependency management. We strongly recommend against mixing uv and conda.

Note: Start jupyter-lab at the root of this repository.

pip install uv
uv sync --python 3.10.11
uv run jupyter-lab
