KeyError: 'o_0' in baselin.py

got a Keyerror when using the baseline algorithm

Hi there,

Could you provide more information as to how to reproduce the error, the full exception traceback and your local environment?

Thanks,
Alessio.

I also encountered this problem, which should be related to the parameters of the CpSolver parameters. The 20-second time might be too short. When I set 'tlim' to None, the program ran for more than 40 minutes without producing any results. However, after commenting out lines 130,131, 132 in baseline.py, I reran the program, and it completed in 2 minutes and produced the results.

Interesting, thanks for sharing your solution.
