Setting Up a Development Environment

Required Dependencies

Python 3.10 is supported on a best-effort basis

As of 2022-02-17 there is support for Python 3.10 when using nix for development.

conda-forge is still in the process of migrating packages to Python 3.10.

Support Matrix

Python Version Python 3.8 Python 3.9 Python 3.10
Operating System
Linux 1
macOS (x86_64)
Windows 3
  1. Install nix

  2. Install gh:

    nix-shell -p gh

    nix-env -iA gh

  3. Fork and clone the ibis repository:

    gh repo fork --clone --remote ibis-project/ibis

  4. Set up the public ibis Cachix cache to pull pre-built dependencies:

    nix-shell -p cachix --run 'cachix use ibis'

  5. Run nix-shell in the checkout directory:

    cd ibis
nix-shell

    This may take awhile due to artifact download from the cache.

Some optional dependencies for Windows are not available through conda/mamba

  1. python-duckdb and duckdb-engine. Required for the DuckDB backend.
  2. clickhouse-cityhash. Required for compression support in the ClickHouse backend.

Python Version Python 3.8 Python 3.9 Python 3.10
Operating System
Linux 1 2
macOS
Windows

  1. Install Miniconda

  2. Install gh

    conda install -c conda-forge gh

  3. Fork and clone the ibis repository:

    gh repo fork --clone --remote ibis-project/ibis

  4. Create a Conda environment from a lock file in the repo:

    cd ibis
conda create -n ibis-dev --file=conda-lock/linux-64-3.9.lock

    cd ibis
conda create -n ibis-dev --file=conda-lock/osx-64-3.9.lock

    cd ibis
conda create -n ibis-dev --file=conda-lock/win-64-3.9.lock

  5. Activate the environment

    conda activate ibis-dev

  6. Install your local copy of ibis into the Conda environment.

    cd ibis
pip install -e .

  7. If you want to run the backend test suite you'll need to install docker-compose:

    conda install docker-compose -c conda-forge

  1. Install Mamba

  2. Install gh

    mamba install -c conda-forge gh

  3. Fork and clone the ibis repository:

    gh repo fork --clone --remote ibis-project/ibis

  4. Create a Conda environment from a lock file in the repo:

    cd ibis
mamba create -n ibis-dev --file=conda-lock/linux-64-3.9.lock

    cd ibis
mamba create -n ibis-dev --file=conda-lock/osx-64-3.9.lock

    cd ibis
mamba create -n ibis-dev --file=conda-lock/win-64-3.9.lock

  5. Activate the environment

    mamba activate ibis-dev

  6. Install your local copy of ibis into the Conda environment.

    cd ibis
pip install -e .

  7. If you want to run the backend test suite you'll need to install docker-compose:

    mamba install docker-compose -c conda-forge

Once you've set up an environment, try building the documentation:

mkdocs serve

  1. Tested in CI. If this doesn't work for you, please file an issue. ↩↩

  2. Should work but doesn't because upstream is broken. Supported on a best-effort basis. ↩

  3. Unlikely to ever be supported or no upstream support. ↩
