I am getting this error when i run poker_ai cluster. Did you ever get this error?

I hit this error as well. Mine was able to run the river and turn clusters, yet on the flop cluster computation, it gave me this same error. It is stuck at 0/155040 (0% completion) for ~15 min, and then spits out this error. Any thoughts or recommendations on how to get around this would be helpful.

[GaussianZero]

This wasn't clear to me, but if you look through the "--help" command, it recommends "starting low" with the parameters. So I followed that advice, and it looks like it completed.

$ ./poker_ai.bin cluster --low_card_rank=10 --high_card_rank=14 --n_river_clusters=3 --n_turn_clusters=3 --n_flop_clusters=3 --n_simulations_{river,turn,flop}=3

check your cpu and mem useage,try concurrent.futures.ProcessPoolExecutor() ->concurrent.futures.ProcessPoolExecutor(max_workers=?)

I had the same problem as OP.
I suspected it was due to lack of memory, so I upgraded my VM to 4 vCPUS and 16GB RAM.
The computation of turn clusters is now on 52%, and the RAM consumption is skyrockting (currently, 9.72GB)

[amirfarazmand]

did you guys create pkl files? There is no documentation on creating them.

[andrepattu]

I'm still encountering the same issues as OP.

I've tried the suggestion from @GaussianZero
--low_card_rank=10 --high_card_rank=14 --n_river_clusters=3 --n_turn_clusters=3 --n_flop_clusters=3 --n_simulations_{river,turn,flop}=3
But it still consumes too much RAM. I'm running it on a 16 GB machine and when I ran the poker_ai cluster command, it creates many processes which eat up 100% of my RAM and kills the process automatically.

Is there a way to limit the RAM usage from this clustering process? Or how did you guys deal with the RAM consumption?

Thanks in advance!
