Installing the Ocean SDK#

Ocean software is supported on the following operating systems:

  • Linux: tested on 64-bit OS

  • Windows: tested on 64-bit Windows 8, 10

  • Mac: tested on macOS 10.15.5 (Xcode 12.2)

Ocean software requires a Python environment. Python versions >=3.9 are supported.

This section explains how to install Ocean software.

Python Virtual Environment#

It’s recommended that you work in a virtual environment on your local machine; depending on your operating system, you may need to first install Python.

  1. Download Python describes how to install Python on your local machine for supported operating system.

    Attention

    For Windows systems, note that only 64-bit Python is supported.

  2. Create a virtual environment for your Ocean work. For example, on Unix systems you might do:

    python -m venv ocean
. ocean/bin/activate

    (On Windows operating system, activating a virtual environment might be done with the Scripts\activate command instead.)

Your machine is now ready to install Ocean software.

Install Ocean Software#

The simplest way to start is to install dwave-ocean-sdk for the full suite of Ocean tools.

You can pip install the SDK inside your newly created virtual environment.

  • For a standard installation of the latest released version from the Python Package Index (PyPI) repository:

    pip install dwave-ocean-sdk

  • Advanced users might directly install the latest (development) SDK from the D-Wave GitHub repository using a command such as,

    pip install git+https://github.com/dwavesystems/dwave-ocean-sdk

Alternatively, you can clone the dwave-ocean-sdk repo and install the SDK to your virtual environment; for example:

git clone https://github.com/dwavesystems/dwave-ocean-sdk.git
cd dwave-ocean-sdk
pip install .

Note: To install a particular tool within the SDK only, follow the link to the GitHub repository for the tool, and follow the installation instructions on the README file.

Set Up Your Environment#

For a full and easy development experience it is recommended that before you start writing code, you complete the setup of your environment with these last steps:

The dwave-ocean-sdk includes an interactive CLI that steps you through setup.

In the virtual environment you created as part of Installing the Ocean SDK above, run the dwave setup command. The output shown below includes the interactive prompts and placeholder replies for a full setup.

Tip

New users can accept the dwave setup command’s defaults (press Enter) for all prompts except the authentication token, which is displayed on the Leap dashboard for your account. The Configuring Access to the Leap Service (Basic) section explains how you can update your work environment’s configuration at any time.

$ dwave setup --auth

Optionally install non-open-source packages and configure your environment.

Install Contributor Ocean Tools#

The interactive dwave setup and dwave install commands of the the dwave-ocean-sdk step you through installation of non-open-source (“contrib”) tools.

If you did not install contributor packages with the dwave setup command in the Set Up Your Environment subsection, or want to add packages at a later time, you can use it again then or use the dwave install command.

$ dwave install --help
Usage: dwave install [OPTIONS] [PACKAGES]...

   Install optional non-open-source Ocean packages.

Options:
  -l, --list     List available contrib (non-OSS) packages
  -a, --all      Install all contrib (non-OSS) packages
  -v, --verbose  Increase output verbosity
  --help         Show this message and exit.

Both commands describe the tools and enable you to select which if any to install.

Most Ocean tools solve problems on a solver, which is a compute resource such as a D-Wave quantum computer or CPU, and might require that you configure a default solver. The Configuring Access to the Leap Service (Basic) describes the next step of setting up your environment, how to configure your system to access D-Wave or other remote solvers.
