With multiple bots

from engine.gym_env import PokerEnv 

env = PokerEnv(num_rounds=1000)
(obs1, obs2), info = env.reset()
bot1, bot2 = random_bot, random_bot

done = False
while not done:
    if obs1["is_my_turn"]:
        action = bot1(obs1)
    else:
        action = bot2(obs2)
    (obs1, obs2), (reward1, reward2), done, trunc, info = env.step(action)

With a single bot (enemy bot fixed)

env = PokerEnv(num_rounds=10, opp_bot=random_bot)
(obs1, obs2) = env.reset()
bot = random_bot

done = False
while not done:
    action = bot(obs)
    obs, reward, done, trunc, info = env.step(action)
