Updates sentence-transformers from 5.6.0 to 5.6.1

Release notes

Sourced from sentence-transformers's releases.

v5.6.1 - Flash Attention Fix for XLM-R and RoBERTa Models

This patch release fixes silently degraded embeddings for RoBERTa-family models when flash attention is requested with transformers v5, notably every XLM-R based multilingual embedding model (BAAI/bge-m3, intfloat/multilingual-e5-large, etc.). The bug affected v5.5.0, v5.5.1, and v5.6.0.

Install this version with

# Training + Inference
pip install sentence-transformers[train]==5.6.1
Inference only, use one of:
pip install sentence-transformers==5.6.1
pip install sentence-transformers[onnx-gpu]==5.6.1
pip install sentence-transformers[onnx]==5.6.1
pip install sentence-transformers[openvino]==5.6.1
Multimodal dependencies (optional):
pip install sentence-transformers[image]==5.6.1
pip install sentence-transformers[audio]==5.6.1
pip install sentence-transformers[video]==5.6.1
Or combine as needed:
pip install sentence-transformers[train,onnx,image]==5.6.1

Fix position_ids offsetting for RoBERTa-family models when flattening inputs (#3879)

Since v5.5.0, the Transformer module flattens text-only batches into one packed sequence when flash attention is requested, skipping all padding overhead for a notable performance improvement. The position_ids of that packed sequence restart at 0 for every text, which is correct for the vast majority of models. RoBERTa-family architectures however compute positions as padding_idx + 1 + n for the n-th token, so every token read a position embedding shifted by padding_idx + 1 (usually 2). Nothing crashes, the embeddings are just silently worse.

from sentence_transformers import SentenceTransformer
An affected configuration: flash attention with an XLM-R based model
model = SentenceTransformer(
"BAAI/bge-m3",
model_kwargs={"attn_implementation": "flash_attention_2"},
)

Measured on BAAI/bge-m3:

Evaluation	padded	packed, 0-based positions	packed, with this fix
stsb test Spearman	0.8485	0.7239	0.8485
NanoBEIR mean nDCG@10	0.6041	0.5414	0.6050

The quality loss recovers exactly once the offset is applied. The fix scans the loaded model's modules once for an int padding_idx stored next to a learned position_embeddings table, and offsets the packed position_ids when that pair is found. An audit of transformers finds 16 architectures with that pair (roberta, xlm_roberta, xlm_roberta_xl, camembert, roberta_prelayernorm, xmod, data2vec_text, longformer, luke, ibert, mpnet, markuplm, lilt, layoutlmv3, esm, and pp_doclayout_v2), all offset by exactly padding_idx + 1, and no 0-based or rotary architecture matches.

You are only affected if you encoded text with flash attention requested on transformers v5 with a RoBERTa-family checkpoint. The default padded path (e.g. sdpa) was never affected, and neither were MPNet models like all-mpnet-base-v2 despite mpnet appearing in the audit: transformers does not support flash attention for MPNet at all. If you did index a corpus with such a configuration, re-encode it after upgrading: pre-fix embeddings score notably worse and do not mix with post-fix embeddings.

Updates ruff from 0.15.21 to 0.16.0

Release notes

Sourced from ruff's releases.

0.16.0

Release Notes

Released on 2026-07-23.

Check out the blog post for a migration guide and overview of the changes!

Breaking changes

• Ruff now enables a much larger set of rules by default (413, up from 59). See the blog post for more details and the new Default Rules page for a full listing of the enabled rules. Note that this is primarily an expansion, but 18 of the more opinionated pycodestyle (E) and pyflakes (F) rules have been removed from the default set: E401, E402, E701, E702, E703, E711, E712, E713, E714, E721, E731, E741, E742, E743, F403, F405, F406, and F722.

• Ruff can now format Python code blocks in Markdown files and will do this by default. See the documentation for more details.

• Ruff now supports ruff: ignore comments at the ends of lines, like noqa comments, or on the line preceding a diagnostic. For example, these both suppress an unused-import (F401) diagnostic:

  import math  # ruff: ignore[F401]
  ruff: ignore[F401]
  import os

• Fixes are now shown in check and format --check output:

  ❯ ruff format --check .
  unformatted: File would be reformatted
   --> try.md:1:1
    |
  1 | ```python
    - import   math
  2 + import math
  3 | ```
    |
  1 file would be reformatted

  This example also shows off the Markdown formatting.

• format --check now supports the same output formats as the linter, including the github and gitlab outputs for rendering annotations in CI:

  ❯ ruff format --check --output-format github .
  ::error title=ruff (unformatted),file=try.md,line=2,col=8,endLine=2,endColumn=10::try.md:2:8: unformatted: File would be reformatted

  See the CLI help or documentation for the full list of supported formats.

• The filename, location, end_location, fix.edits[].location, and fix.edits[].end_location fields in the JSON output format may now be null rather than defaulting to the empty string and row 1, column 1, respectively.
