bug when running MARL algorithm Qmix in pettingzoo about di-engine

[PaParaZz1]

It seems that this bug is due to the timeout of the reset operation in the pettingzoo environment. Could you provide the exact version of pettingzoo in your PC (the version we commonly use is 1.22.4). Additionally, you can modify the configuration settings, such as changing the environment manager type from subprocess to base. This adjustment can facilitate the debugging process for issues pertaining to the environment.

My version is 1.24.3. When I change it to 1.22.4, everything seems to be OK. But is it normal for training with the QMIX algorithm in a ptz_simple_spread scenario to take over an hour without finishing?
