If the new behavior is correct (e.g., better ball detection), update baselines. If behavior worsens, rollback to 4.11.0 and report an issue. + +### Q: How long does the upgrade take? +**A:** Approximately 45-60 minutes for building OpenCV from source on Raspberry Pi 4/5. + +### Q: Can I skip directly from 4.9.0 to 4.12.0? +**A:** Yes, no intermediate versions are required. Just follow the upgrade steps above. + +### Q: What about CUDA support? +**A:** Not applicable for Raspberry Pi (no NVIDIA GPU). CUDA 13.0 support in 4.12.0 is for x86 development setups only. + +--- + +**Maintained by:** PiTrac Development Team +**Last Updated:** 2026-02-12 +**Next Review:** After field testing completion (Week 6) diff --git a/pitrac-cli/cmd/install.go b/pitrac-cli/cmd/install.go index bb7e0d4..1f5819c 100644 --- a/pitrac-cli/cmd/install.go +++ b/pitrac-cli/cmd/install.go @@ -669,7 +669,7 @@ rpicam-still --version || true }, }, shellStep("clone and build OpenCV", ` -OPENCV_VERSION="${REQUIRED_OPENCV_VERSION:-4.11.0}" +OPENCV_VERSION="${REQUIRED_OPENCV_VERSION:-4.12.0}" OPENCV_DIR="${OPENCV_DIR:-$HOME/opencv-${OPENCV_VERSION}}" OPENCV_CONTRIB_DIR="${OPENCV_CONTRIB_DIR:-$HOME/opencv_contrib-${OPENCV_VERSION}}" ENABLE_PYTHON="${OPENCV_ENABLE_PYTHON:-0}" From 2c4a724cbefc1b5472dda17d7916def67452e34f Mon Sep 17 00:00:00 2001 From: Jesse Hernandez Date: Thu, 12 Feb 2026 16:26:19 -0800 Subject: [PATCH 2/2] docs: fixing workflow for release --- .github/workflows/release-pitrac.yml | 30 +++++++++++++++++++++++++++- 1 file changed, 29 insertions(+), 1 deletion(-) diff --git a/.github/workflows/release-pitrac.yml b/.github/workflows/release-pitrac.yml index 6010f39..bc5f4cf 100644 --- a/.github/workflows/release-pitrac.yml +++ b/.github/workflows/release-pitrac.yml @@ -107,14 +107,42 @@ jobs: echo "zip_path=${zip_path}" >> "${GITHUB_OUTPUT}" + - name: Delete existing release if present + continue-on-error: true + shell: bash + run: | + gh release delete "${{ steps.meta.outputs.tag }}" --yes --cleanup-tag || true + env: + GH_TOKEN: ${{ secrets.GITHUB_TOKEN }} + - name: Publish GitHub Release id: publish - continue-on-error: true uses: softprops/action-gh-release@v2 with: tag_name: ${{ steps.meta.outputs.tag }} target_commitish: ${{ github.sha }} name: ${{ steps.meta.outputs.release_name }} + draft: false + prerelease: ${{ steps.meta.outputs.prerelease == 'true' }} + generate_release_notes: true + files: ${{ steps.bundle.outputs.zip_path }} + fail_on_unmatched_files: true + make_latest: true + env: + GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }} + + - name: Retry upload on failure + if: failure() && steps.publish.outcome == 'failure' + uses: softprops/action-gh-release@v2 + with: + tag_name: ${{ steps.meta.outputs.tag }} + target_commitish: ${{ github.sha }} + name: ${{ steps.meta.outputs.release_name }} + draft: false prerelease: ${{ steps.meta.outputs.prerelease == 'true' }} generate_release_notes: true files: ${{ steps.bundle.outputs.zip_path }} + fail_on_unmatched_files: true + make_latest: true + env: + GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
