为什么每一次都会弹出To https://git.nevint.com/multimodal/floorai_model_server_lite.git ! [rejected] jiangchen -> jiangchen (non-fast-forward) error: failed to push some refs to 'https://git.nevint.com/multimodal/floorai_model_server_lite.git' hint: Updates were rejected because the tip of your current branch is behind hint: its remote counterpart. Integrate the remote changes (e.g. hint: 'git pull ...') before pushing again. hint: See the 'Note about fast-forwards' in 'git push --help' for details.

这个错误提示是因为你的本地分支与远程分支不一致导致的。你需要进行以下操作来解决这个问题：

1. 首先，运行以下命令来拉取远程分支的最新代码：

git pull origin jiangchen

2. 如果在拉取代码时出现冲突，你需要解决这些冲突。打开冲突文件，手动合并代码，并提交解决冲突后的代码。

3. 当拉取并解决冲突后，再次尝试推送代码：

git push origin jiangchen

这样，你的本地分支应该能够成功推送到远程分支。
