Installing Ocean Tools

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 >=3.8 are supported.

This section explains how to install Ocean software, either the entire suite of tools or particular tools[1] from the D-Wave GitHub repositories listed under the packages tab.

[1]

Although individual Ocean packages accept dependencies within a range of versions, not all combinations are tested. Only versions of individual Ocean tools that form part of an official release of the Ocean SDK are guaranteed to work together.

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
python setup.py install

Note: To install a particular tool within the SDK only, follow the link to the GitHub repository for the tool, as listed in the navigation bar, 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:

• Authorizing Access to Leap

  Optionally authorize Ocean to access your Leap account to facilitate token management.

• Install Contributor Ocean Tools

  Adds non-open-source tools such as the Problem Inspector.

• Configuring Access to Leap’s Solvers

  Sets defaults used for accessing D-Wave compute resources.

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

In the virtual environment you created as part of Installing Ocean Tools, 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. Section Configuring Access to Leap’s Solvers 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 section, 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 system or CPU, and might require that you configure a default solver. Configuring Access to Leap’s Solvers describes the next step of setting up your environment, how to configure your system to access D-Wave or other remote solvers.
