11 months ago 我尝试在 MIR 和 UR 环境中加载到稳定基线 3。似乎库无法迭代observation_space.spaces.items（）。向遇到此问题的任何人寻求帮助

Hello, do you want to use the HER algorithm in SB3? I have also encountered this problem and it seems that there is no way to solve it.
i tried loading in both MIR and UR environment to Stable Baseline3. It seems like the library wasn't able to iterate the observation_space.spaces.items(). Looking for help from anyone experience with this issue
