success | load in 8 bit. it runs on one-3090ti (24G)

[stevezhang88]

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
