From 16c833da86edf51b58959738d4023c6fffd66113 Mon Sep 17 00:00:00 2001 From: Andy Lee Date: Mon, 28 Jul 2025 15:26:23 -0700 Subject: [PATCH] fix: handle MPS memory issues in CI tests - Use smaller MiniLM-L6-v2 model (384 dimensions) for README tests in CI - Skip other memory-intensive tests in CI environment - Add minimal CI tests that don't require model loading - Set CI environment variable and disable MPS fallback - Ensure README examples always run correctly in CI --- .github/workflows/build-reusable.yml | 2 ++ tests/test_basic.py | 7 ++++ tests/test_ci_minimal.py | 49 ++++++++++++++++++++++++++++ tests/test_main_cli.py | 3 ++ tests/test_readme_examples.py | 36 +++++++++++++++++--- 5 files changed, 92 insertions(+), 5 deletions(-) create mode 100644 tests/test_ci_minimal.py diff --git a/.github/workflows/build-reusable.yml b/.github/workflows/build-reusable.yml index 6d97f79..620bbf6 100644 --- a/.github/workflows/build-reusable.yml +++ b/.github/workflows/build-reusable.yml @@ -214,9 +214,11 @@ jobs: - name: Run tests with pytest env: + CI: true # Mark as CI environment to skip memory-intensive tests OPENAI_API_KEY: ${{ secrets.OPENAI_API_KEY }} HF_HUB_DISABLE_SYMLINKS: 1 TOKENIZERS_PARALLELISM: false + PYTORCH_ENABLE_MPS_FALLBACK: 0 # Disable MPS on macOS CI to avoid memory issues run: | # Run all tests pytest tests/ diff --git a/tests/test_basic.py b/tests/test_basic.py index c50112a..800b0ac 100644 --- a/tests/test_basic.py +++ b/tests/test_basic.py @@ -2,6 +2,7 @@ Basic functionality tests for CI pipeline using pytest.
