How can I do code format before I send a PR ？

You can (and should) use clang-format for code formatting. It's available as a package on basically all Linux distributions.

I recommend using the Git-integration which only formats the lines of code that you have changed.

git clang-format formats all the changes that have not yet been commited.

If you have already committed your changes, then git clang-format HEAD~1 also formats the changes from the last commit.

I notice XLA code-format ci always fail, and the format-ci logs show these errors are not from my pr. What should I do in this situation?

There seems to be a disagreement between different versions of clang-format about what's the correct formatting for algebraic_simplifier_test.cc. Please mention in the PR description that the suggested formatting changes are unrelated to your PR
