sorry, first time use this function.

My problem is that my custom env need to pass a unique parameter to init the env. like an Id. with gym.ayncvectorenv i can use the lambda function to generate this kind of vec envs. But How can i do this with envpool?

what's your customized env? is it already in envpool implementation?

Thank you for your reply.

My env is just like pendulum v0.

env = gym.vector.AsyncVectorEnv([ lambda: gym.make("Pendulum-v0", g=9.81), lambda: gym.make("Pendulum-v0", g=1.62) ])

I'd like to pass different g to each new environment. If there is a way to do this in envpool, please let me know!

Thank you so much.
