Is the same reason for baichuan-13b? #530 |
Yes. I have tested it on both baichuan13b and 7b, and it can output normal output under tp. |
Can I use this PR directly on 13B？ |

Is this part the only part that actually changes the code logic? Can you remove other format-only modifications and use format.sh script provided by us to re-format the code? Thanks!
