dwave-cloud-client

library0.14.6pypypi✓ verified 86d ago

A minimal client for interacting with D-Wave cloud resources, including solvers (QPU and hybrid) via the D-Wave API. Current version 0.14.4, requires Python >=3.10. Release cadence is irregular, with several minor releases per year.

Client

✓ from dwave.cloud import Client

Standard import for high-level client.

SolverApiClient

✓ from dwave.cloud.api.client import SolverAPIClient

Low-level API client.

Initialize client, list available solvers.

from dwave.cloud import Client # Replace with your D-Wave API token or set DWAVE_API_TOKEN env var token = os.environ.get('DWAVE_API_TOKEN', '') with Client(token=token) as client: solvers = client.get_solvers() for solver in solvers: print(solver.id, solver.name)

Debug

Known issues

breakingIn version 0.14.0, solver identification changed from a unique string `id` to a dictionary `identity` with `name` and `graph_id`. Code that relies on `solver.id` as a string will break.

fix

Use `solver.identity` (a dict) or `solver.name` for hybrid solvers. For QPU solvers, use `solver.graph_id` for unique identification.

affects: >=0.14.0,<0.14.0

deprecated`Solver.is_vfyc` property is deprecated since dwave-cloud-client 0.14.1 and will be removed in a future version.

fix

Use `'qubit' in solver.properties.get('category', '')` or check solver category via the solver's `properties` dict.

affects: >=0.14.1

gotchaClient closes resources on exit. Using `Client` outside a context manager and not calling `.close()` may leak connections or fail on garbage collection.

fix

Always use `with Client(...) as client:` or call `client.close()` when done.

affects: all

Errors

Common errors & fixes

AttributeError: 'Solver' object has no attribute 'id'

Upgraded to dwave-cloud-client 0.14.0+ which changes solver identification from string `id` to dict `identity`.

fix

Use `solver.identity` instead of `solver.id`, or check `solver.name` for hybrid solvers.

dwave.cloud.exceptions.ConfigFileError: Config file 'dwave.conf' not found or invalid

Missing or malformed D-Wave configuration file or environment variables.

fix

Set `DWAVE_API_TOKEN` environment variable or create a valid `dwave.conf` file. See https://docs.dwavesys.com/docs/latest/doc_getting_started.html.

requests.exceptions.ConnectionError: HTTPSConnectionPool(host='cloud.dwavesys.com', port=443): Max retries exceeded

Network issues or D-Wave API endpoint unreachable.

fix

Check internet connectivity and firewall settings. Ensure the API endpoint URL is correct (default is https://cloud.dwavesys.com/sapi).
