Subject: ci : add coreml job that converts base.en to coreml [no ci] (#2981)
X-Git-Tag: upstream/1.7.5~18
X-Git-Url: https://git.djapps.eu/?a=commitdiff_plain;h=04b9508fb3bb4556763f6addf3e53a6edabdef4b;p=pkg%2Fggml%2Fsources%2Fwhisper.cpp

ci : add coreml job that converts base.en to coreml [no ci] (#2981)

* ci : add coreml job that converts base.en to coreml [no ci]

This commit adds a new job to the CI pipeline that downloads the base.en
model and converts it to CoreML format. The CoreML model is then packed
into a zip file and uploaded as an artifact.

This will only be done for pushes to master, releases, or pre-releases.

Refs: https://github.com/ggerganov/whisper.cpp/issues/2783

* coreml : remove publishing of coreml model

* ci : add GGML_OPENMP=OFF to ubuntu-22-gcc-sanitized
