Sending Scripts to the QPU about dwave-ocean-sdk HOT 5 CLOSED

So for the DWaveSampler, every time you run sample() or sample_ising(), you are actually sending the problem to the QPU and the result returned is the sample taken from the QPU.

The first part of the code with the client, is probably unnecessary.
Once you have run the dwave config create command, set up your information, and the dwave ping command works, you should be able to create a DWaveSampler without any parameters.

You should be able to just run the second block of code as is, without the client set up.
The client is for more advanced functionality that most users will likely not need.
At least not to start out with.
The functionality is similar, and some of it is used by DWaveSampler if I'm not mistaken.

The dwave ping command will work as long as your virtual environment is activated and your config is set up properly, and as long as dwave ping works, you should be able to send problems to the QPU.

That makes a lot of sense, thanks. You explained that very clearly, I sincerely appreciate it.

Hi @Bhaney44,

Were you able to set up your virtualenv?

After setting it up, did you install the dwave-ocean-sdk?

The networkx library should be installed as a dependency with dwave-ocean-sdk.

Are you able to import dimod?
import dimod

Best regards,

Dave.

Yeah I'm all good. Thanks @davage.

I was wrong, I tried tonight and had the same problem. The issue is I can run dwave ping and get a fine response. I can also run a random problem. However, the problem is I cannot send python scripts to the QPU. The Docs skip over how to actually send a problem to the QPU. So, here in the docs is the problem. While I can set up a config, but the docs say

Alternatively, from within your code or a Python interpreter you can query solvers available for a SAPI URL and API token using dwave-cloud-client get_solvers() function.

But, I'm struggling to accomplish this. The code says:

from dwave.cloud import Client
client = Client.from_config(token='ABC-123456789123456789123456789')
client.get_solvers()

But, that returns an error for me. Traditionally, if you type python in the command line you can code in python, but that doesn't work with the QPU. Similarly, you can type Python file_name.py to run a file from the command line on the CPU. I want to get to here:

from dwave.system.samplers import DWaveSampler
from dwave.system.composites import EmbeddingComposite
sampler = EmbeddingComposite(DWaveSampler())
response = sampler.sample_ising({'a': -0.5, 'b': 1.0}, {('a', 'b'): -1})
response.data_vectors['energy']  

Either directly from the command line or even better if I can save this as a .py file and simply send it to the QPU. But, with the QPU, there isn't an intuitive way to send or run scripts. In short, I have scripts written - how do I send those python scripts to the QPU? In other words how do you get from sending a dwave ping to sending a Python script.

I hope this makes sense. Thanks again for your help. I sincerely appreciate it.
