Question on the version of pyqubo; [AttributeError: 'cpp_pyqubo.Model' object has no attribute 'decode_solution'] #1

Hi, when running _vehicle_routing_problem.ipynb, I encoutered an error of AttributeError: 'cpp_pyqubo.Model' object has no attribute 'decode_solution'_. I think it might be due to the wrong version of pyqubo, so could you kindly tell me which version of pyqubo you used. Could you please provide the full dependencies list to run your code? Thanks a lot!

Sorry, I created this script using Google Colaboratory at the time, so I don't know about the library dependencies. However, based on when the script was written and PyPI's release history, PyQUBO's version is probably 0.40 (very old...).

I have tried the PyQUBO version of 0.4.0 but the error still exists QAQ. Anyway, thanks for your quick response~
