I download model to local machine. then use FastChat env. so I don't need create another env for MOSS. it works!
Because 24G is not enough to MOSS( fnlp/moss-moon-003-sft), I try load model in 8 bit. It's ok and make response very quickly.
show my code:

generate函数我使用的是MOSS原文中的方式。目前来看,可以运行。你先试试FastChat项目,能否正常运行?看看是不是transformers的库或者tokenizer库需要升级了?

为了验证是不是只有MOSS有这个问题,我特意在ChatGLM-6B上用了相同的办法,同样也是卡住很久没有回复
