An error in psro_leduc_poker.py

[Waiting-TT]

when I run psro_leduc_poker.py, an error about ray occurs as follows:

I would be appreciate if you could give me some suggestions about how to solve it.

Additionally, I use the version of ray=1.0.0 and cloudpickle=1.6.0, because ray=1.8.0 is incompatible with cloudpickle=1.6.0(the same incompatible problem can see https://blog.csdn.net/weixin_42769131/article/details/121526206 ).
