run error

Hi,
When I run python nurse_scheduling.py, following error occurred:

Traceback (most recent call last):
File "nurse_scheduling.py", line 166, in
sampler = LeapHybridSampler()
File "/Users/jinzhe/opt/anaconda3/lib/python3.8/site-packages/dwave/system/samplers/leap_hybrid_sampler.py", line 97, in init

File "/Users/jinzhe/opt/anaconda3/lib/python3.8/site-packages/dwave/cloud/client.py", line 386, in init
raise ValueError("API token not defined")
ValueError: API token not defined

I installed dwave with pip install dwave-system.
Could you help me?
Thanks,

Hi @rlacjfjin,

To use the LeapHybridSampler, you’ll need an API Token from Leap for authentication. These two articles might be helpful if you haven’t seen them yet:
