* conditional python version

* retry

* temporary skip llm-cpp-build

* apply on llm-unit-test-on-arc

* fix

* add llm-cpp-build dependency

* use GITHUB_OUTPUT instead of set-output

* check nightly build

* fix quote

* fix quote

* add llm-cpp-build dependency

* test nightly build

* test pull request
