        This probably means that you are not using fork to start your
        child processes and you have forgotten to use the proper idiom
        in the main module:

            if __name__ == '__main__':
                freeze_support()
                ...

        The "freeze_support()" line can be omitted if the program
        is not going to be frozen to produce an executable.

Thanks for your bug report @zanussbaum . I did test this on a few machines before deploying but I must have not captured your specific case - sorry about that.

Would you be able to try pip installing into a conda, virtualenv or something similar, environment and seeing if that works? I'll install python 3.8 on my Mac and see if I can replicate your problem

[zanussbaum]

conda create -n pluribus conda activate pluribus pip install poker_ai poker_ai I don't have a ton of experience with conda, but still getting the same error when doing above.

[fedden]

Thanks so much for this @zanussbaum

I've just tried on Linux and Mac OS X, and it's a OS X issue.

If you have a linux distro you can use in the meantime, then please use that (it should be fine on that 🤞), otherwise we'll try to find some time to look into supporting OS X. Although just heads up, we are currently focusing on other projects so PRs are very welcome here and we can't guarentee a timely response 🙂

I also encountered this error in Win10, but normally use linux, so I didn't troubleshoot windows too much.

I wonder if trying python 3.7 would work in the meantime?

[zanussbaum]

hm i'll test it out. either way, i'm excited to try it out!

[johanpettersson1]

[fedden]

can you try again with a Linux OS please @johanpettersson1 ?

[johanpettersson1]

I don't have a linux machine at home sorry :(

[alexandermaas]

I was facing similar issues on my Macbook. The fix for this bug was straightforward as indicated here:

I've implemented a fix for it in PR123. Could you please merge?

[amirfarazmand]

Great Alex. This worked. What is the result of running clustering, my computer needs 6 hours to finish this, does this need to be ran every time or the results can be saved?

[amirfarazmand]

12 hrs and still only here, do I need to run this on a server? C:\Program Files\WindowsApps\PythonSoftwareFoundation.Python.3.9_3.9.1776.0_x64__qbz5n2kfra8p0\lib\runpy.py:127: RuntimeWarning: 'poker_ai.clustering.runner' found in sys.modules after import of package 'poker_ai.clustering', but prior to execution of 'poker_ai.clustering.runner'; this may result in unpredictable behaviour warn(RuntimeWarning(msg)) 31%|██████████████████████▏ | 181277/581400 [4:32:32<15:19, 435.23it/s]

[amirfarazmand]

24 hrs and still going on a Core i5 vPro CPU, does anyone know how long this will take? I can see a few .joblib files have been created, couldn't someone just copy these files rather than everyone creating these?

[amirfarazmand]

I see this is eventully created after 1.5days card_info_lut.joblib. This should have been really shared.

[amirfarazmand]

This repo seem to have too many issues, this works like a charm: https://github.com/datamllab/rlcard

[kabua]

Found a simple fix for this, see.
