Could not use alfworld successfully

[cyente]

根据 https://github.com/alfworld/alfworld 安装完成后，执行task依旧会有报错。

（这块的环境问题让人十分头疼，不知道是否有解决方案？）

Traceback (most recent call last):

Try our docker images? See https://github.com/THUDM/AgentBench/blob/main/docs/tutorial.md#step-2-prepare-docker-environment

I removed all "multiprocessing" part then it worked.
