Problem with take() in bidder.py

[majun69]

Greetings!
I'm trying to use the Bidder module (z3b version) in your repository, but encountered the following problem.
I first created a bidder using a BidderFactory

self.bidder = BidderFactory.default_bidder()

then

self.bidder.find_call_for(hand, call_history)

which raised the following exception

File "C:\saycbridge-master\src\z3b\bidder.py", line 207, in __exit__
    _solver_pool.restore(previous_history._solver.take())
AttributeError: 'functools._lru_cache_wrapper' object has no attribute 'take'

It seems that the _solver is missing a take() method. I'm wondering what's the expected behavior of take() here. Is there a possible workaround? Thanks.

Honestly, I've not touched that code in almost a decade at this point. You're probably more of an expert on it than I am. It was written before Python converted to python 3, so it's possible it doesn't even compile cleanly without a little editing.

https://www.saycbridge.com/ is still running the "kbb" branch (knowlege based bidder). I think the z3 branch is better, but will likely require some love to get it working well.
