Calling seed externally is deprecated; call reset(seed=seed) instead

I'm trying to run this tutorial code, but when I run the line with ss.concat_vec_envs_v1, I get this error:

Hiya, apologies for taking awhile to see this. Are you trying to run this code from the PyPI release with the associating PettingZoo PyPI release? Or is this error happening with the gh branch of code?

Hey, I'm going to close this due to inactivity, please let us know if you have any additional help :)

Hi, I am getting the same error with and I am ss.concat_vec_envs_v1

I have a

SuperSuit 3.3.3 PettingZoo 1.18.1

[timf34]

Hi, I am also getting this same error, also with supersuit==3.3.3 and pettingzoo==1.18.1. Both of which are using the PyPi releases (i.e. they're installed via pip) Thanks
