Modernize dependencies and CI infrastructure by rom1504 · Pull Request #216 · criteo/autofaiss

rom1504 · 2025-08-09T21:16:25Z

Summary

This PR modernizes the autofaiss project's dependencies and CI infrastructure:

• Dropped Python 3.8/3.9 support and updated minimum requirement to Python 3.10
• Upgraded PySpark from 3.2.2 to 4.x for Java 17 compatibility
• Enhanced FAISS robustness for distributed index merging operations
• Updated CI workflows to use Python 3.10 across all jobs

Key Changes

Dependency Updates

Python: Minimum version >=3.10 (was >=3.8)
PySpark: >=4.0.0,<5.0.0 (was version-specific constraints)
pyarrow/embedding_reader: Updated to latest compatible versions

Code Fixes

NumPy 2.x compatibility: Added explicit float() conversions around NumPy operations in:
- autofaiss/metrics/reconstruction.py
- autofaiss/indices/index_utils.py
- autofaiss/external/scores.py
- autofaiss/utils/json_encoder.py
FAISS robustness: Enhanced distributed index merging with validation checks:
- autofaiss/indices/distributed.py - Production merge code
- tests/unit/test_quantize.py - Test helper functions
- Added defensive programming for CI environment race conditions

Infrastructure Updates

GitHub Actions: Updated all workflows to use Python 3.10
- CI tests: Python matrix ['3.10', 3.11, 3.12] (was [3.8, 3.9, '3.10', 3.11, 3.12])
- Lint job: Python 3.10 (was 3.8)
- Documentation: Python 3.10 (was 3.9)
Makefile: Fixed PEX build shell escaping for PySpark constraints
Java 17: All workflows now use Java 17 for PySpark 4.x compatibility

Test Results

✅ Local testing: All tests pass with 10.00/10 pylint score
✅ Type checking: Clean mypy results
✅ Formatting: Black formatting compliant
✅ PEX builds: Successful with new dependency constraints

Breaking Changes

Minimum Python version: Now requires Python 3.10+
PySpark version: Upgraded to 4.x (may require Java 17 in production)

…ents" This reverts commit 4273f3e.

The distributed test was failing in CI due to memory corruption when using NumPy 2.x with PySpark 4.0 and FAISS 1.11. The error manifested as: 'Invalid key=94143314170815 nlist=1' where the large key appears to be a corrupted 64-bit memory address (0x559f72cc93bf). Pinning to numpy<2 (1.26.4) resolves the memory management incompatibility between NumPy 2.x's new memory layout and FAISS/PySpark serialization. This is a temporary fix until the upstream compatibility issues are resolved. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>

Add detailed logging to understand CI failures: - Version information (Python, NumPy, FAISS, PySpark) - Distributed build success/failure tracking - Search operation results and shapes - Special detection for empty search results (PySpark worker failure) This will help diagnose the Python 3.10 CI failure where search returns empty results due to PySpark worker crashes.

Add comprehensive logging to pinpoint the exact crash location: - _merge_to_n_indices: Entry parameters, batch creation, RDD operations - _merge_index: File processing, FAISS operations in each worker - _merge_from_local: Individual FAISS read_index and merge_into calls This targets the actual crash point in distributed.py:246 where metrics_rdd.collect() fails with PySpark worker crashes in Python 3.10 CI.

Convert all debugging print() calls to proper logger.debug/error calls: - Better integration with existing logging infrastructure - Avoids lint issues (trailing whitespace, import outside toplevel) - Follows logging best practices with parameterized messages - Maintains same debugging capability with proper log levels This resolves lint failures while preserving debugging functionality for future PySpark/FAISS compatibility issues.

- Move traceback import to module level to avoid 'import-outside-toplevel' - Remove trailing whitespace - Organize imports properly - Achieve 10.00/10 pylint score All debugging functionality preserved while maintaining code quality standards.

Previous crashes were fixed by reverting problematic validation code. Now testing if NumPy 2.x works with our logging infrastructure in place. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>

NumPy 2.x still causes PySpark worker crashes in CI. Reverting to numpy<2 which is known to work. Also cleaned up all debugging logs that were added for troubleshooting. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>

maybe updating pyspark is the cause

rom1504 · 2025-10-05T20:26:02Z

I think to move forward here our best bet is to try updating one dep, open a PR to run all the tests; then another dep etc until we find the dep that's causing the issue

Pulled your changes into my local workspace and incorporated the suggestions
#218

Unfortunately, I am unable to figure out the unit test failure for python 3.10.

Do you have any clue on why this is failing ?
