Is this plugin up to date? Can we use it?

[arcondello]

Hi @chorusg, yes it is. Unless there was some bug you were seeing to prevent you from using it?

[chorusg]

Do you have any simple code example to use this plugin?

There are a few examples in the README. If you would like additional help, I would recommend creating a post in our community.

It didnt work when I copied the source code in Readme and run in cloud codespace. Any change needs to be made?

[arcondello]

Can you be more specific? Specifically can you provide a minimal, reproducible example , as well as the full traceback that your are seeing?

[chorusg]

1. Open codespace on D-Wave scikit-learn Plugin
2. Run: pip install dwave-scikit-learn-plugin
3. Run: pip install dwave-system
4. Run: pip install -r requirements.txt
5. Run: python setup.py install
6. Run: dwave auth login --oob
   Returned

Usage: dwave [OPTIONS] COMMAND [ARGS]...
Try 'dwave --help' for help.

Error: No such command 'auth'.

What is wrong with the process?

[arcondello]

I see, in this case you are installing the package twice. The first with pip install dwave-scikit-learn-plugin and the second with requirements.txt/setup.py. The second is a source install it pulls in an older dwave-cloud-client version that does not have the auth feature.

Try running just

pip install dwave-scikit-learn-plugin --upgrade
dwave auth login --oob

[chorusg]

After running 2 of them, this issue appears:
bash: dwave: command not found

[arcondello]

It looks like somehow dwave-cloud-client got uninstalled. Can you try

pip install dwave-scikit-learn-plugin --upgrade --force

which will install everything from scratch. Also, if there is an error can you please post the entire install output as well as the entire error traceback?

[chorusg]

Created a file name: rtest.py with content:

from sklearn.datasets import load_breast_cancer
from dwave.plugins.sklearn import SelectFromQuadraticModel

X, y = load_breast_cancer(return_X_y=True)

X_new = SelectFromQuadraticModel(num_features=20).fit_transform(X, y)

---

Then run: python rtest.py

The terminal showed this result:

[arcondello]

You need access to the D-Wave quantum computers and hybrid solvers. You can get access by running

dwave auth login --oob

I believe with the fresh install that should work now.

[chorusg]

It was authorised but still show the above error.

[arcondello]

What is the output of dwave ping?

[chorusg]

We had got : Authorization completed successfully. You can now use "dwave auth get" to fetch your token.

then "dwave ping" returned: Error: Invalid configuration: API token not defined (code: 1)

[arcondello]

As the message states you need to run dwave auth get to get an authorization token which will give you access to the
solver.

Or you can do this in one step with dwave auth login --oob && dwave config create --auto-token.
