I'm having some trouble when trying to use the LeapHybridCQMSampler in the connection with cloud.dwavesys.com. This is the error log:
SSLError: HTTPSConnectionPool(host='cloud.dwavesys.com', port=443): Max retries exceeded with url: /metadata/v1/regions/ (Caused by SSLError(SSLCertVerificationError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate (_ssl.c:1108)')))
I tried using the permissive_ssl parameter, but it doesn't make any difference. I also tried running it in several devices and couldn't solve it either.
Here is the code I'm using, where I just build a simple CQM and send it to the sampler:
import dwave.system
from dimod import Integer, ConstrainedQuadraticModel
x = [Integer(f'x_{i}') for i in range(4)]
cqm = ConstrainedQuadraticModel()
H_Objective = -5*x[0] - x[1] + x[2] - x[3]
cqm.set_objective(H_Objective)
cqm.add_constraint(20 - 10*x[0] - x[1] - x[2] - x[3] >=0)
sampler = dwave.system.LeapHybridCQMSampler()
sampleset = sampler.sample_cqm(cqm, num_reads=5000)
