…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>

@rom1504 Can you take a look at this ?

rom1504 · 2025-10-07T18:27:31Z

Since you changed the kind of index I think you just need to change the test assumptions

satishlokkoju · 2025-10-09T05:32:14Z

@rom1504 fixed the test cases. Variance in the nprobe hyperparameter was causing transient test failures.
I’ve now forced nprobe via the input_param argument, making the test cases deterministic.
Let me know if you have any other comments.

rom1504 · 2025-10-09T06:10:19Z

Nice! I think this is ready

rom1504 · 2025-10-09T06:12:13Z

@Mbompr could you please review or send to other folks to review? Looks like I don't have write access to autofaiss anymore

satishlokkoju · 2025-10-11T17:27:48Z

@hitchhicker Could you review this. Or point me to some one who can review this ?

hitchhicker · 2025-10-12T21:04:30Z

@satishlokkoju Sorry I can't help as I don't have write access to it neither.

rom1504 · 2025-10-18T16:36:29Z

can you please keep this open? we will find someone that can merge

Mbompr · 2025-10-19T08:04:20Z

Hello,
Sorry for the late answer. I strangely don't have rights either but will figure out how to get them. I tell you as soon as it's ready.

Mbompr · 2025-10-19T19:57:24Z

 pytest==8.0.1
-pyspark==3.2.2; python_version < "3.11"
-pyspark<3.6.0; python_version >= "3.11"
+pyspark>=4.0.1,<5.0.0


We sadly need to ensure compatibility with PySpark 3.4, do you think it would break anything?

I think it'd be fine to change this change to >= 3.4,<5.0.0

Actually this is only for tests, it should not matter much.
