Trainer no longer calls an overridden gradient_checkpointing_enable after the activation checkpointing rename
### System Info - `transformers` version: 5.23.0.dev0 (main, huggingface/transformers@a85df47ada) - Platform: Linux-6.8.0-1057-aws-x86_64-with-glibc2.35 - Python version: 3.13.9 - PyTorch version: 2.14.1+cu130 - Accelerate version: 1.15.0 ### Who can help? @qgallouedec (author...
Docs: `hidden_states[-1]` of DINOv3 / ViT changed from post-norm to pre-norm in 4.57.2 (not in release notes or migration guide)
Since #40994 (shipped in v4.57.2, and in v5), vision models such as `DINOv3ViTModel` and `ViTModel` use `tie_last_hidden_states=False`: `hidden_states[-1]` is now the last block's output before the final layernorm. Up to v4.57.1 it was identical to `last_hidden_state`. The new...
ZeroShotObjectDetectionPipeline silently drops batched images and misroutes candidate labels
### System Info - **Transformers:** `5.23.0.dev0` (main) - **PyTorch:** `2.11.0+cu130` - **GPU:** NVIDIA Tesla T4 - **Environment:** Kaggle, Linux, CUDA enabled ### Reproduction `ZeroShotObjectDetectionPipeline.__call__()` uses [`zip(image,...
ClapFeatureExtractor forces is_longer=True in fusion mode when every clip is ≤10 s
## Reproduction At batch 1, `is_longer` is always `[True]`, so the clip is routed through the fusion branch even though it is not longer than the window. At batch 8 exactly one index is `True`, and which one changes between calls because the choice is `np.random.randint` and...
Prompt-lookup decoding advances stateful logits processors (CFG, SynthID watermark) on draft tokens, so output differs from generation without prompt lookup
### System Info - transformers 5.21.0 (also reproduced on main @ 494470d6) - torch 2.11.0+cpu, Python 3.12, Linux (WSL2), CPU only - `pip install torch==2.11.0 --index-url https://download.pytorch.org/whl/cpu && pip install transformers==5.21.0` ### Who can help? @Cyrilvallez...
Improve tokenizer validation errors by including the received input type
### Feature request I'd like to improve tokenizer input validation errors by including the actual type received when an invalid input is passed. For example: Currently, the `ValueError` lists the accepted input types but doesn't indicate that an `int` was received. The proposal...
[Regression] EP no longer leaves attention replicated (v5.19)
Since #48859 (**v5.19.0**), DistributedConfig(tp_size=N, ep_size=N) applies the TP plan next to the EP plan, so attention is sharded N ways. Up to **v5.18.0**, expert parallelism applied the EP plan alone and attention stayed replicated. Models with fewer KV heads than tp_size...

set_attn_implementation() does not reach T5 encoder/decoder: model reports SDPA but still runs eager
### System Info - `transformers` main @ `4d536e1f1a` (5.19.0.dev0) - torch 2.11.0, CPU, macOS arm64 ### Description `model.set_attn_implementation("sdpa")` on a T5 model loaded with `attn_implementation="eager"` updates `model.config`, but the encoder/decoder `T5Stack`s (and...
Pixtral Flash Attention 2 uses axial RoPE coordinates as packed sequence boundaries (regression in 5.17.0)
### System Info - Transformers 5.18.0 - Python 3.12 - PyTorch 2.14.0 - flash_attn 2.8.3 ### Who can help? @zucchini-nlp ### Information A PixtralVisionModel raises `CUDA error: an illegal memory access was encountered` with Flash Attention 2 in Transformers 5.17.0 and 5.18.0....
Encoder repetition penalty uses incorrect source rows after beam or sampled-return expansion
### System Info - Transformers: `5.19.0.dev0`, main commit `d6c1e71bd717bf092f8293f0c3c9bd4a5ac5401a`; also reproduced on stable `5.18.0`. - Python: `3.12.14` - PyTorch: `2.14.1+cpu` - Accelerate: `1.15.0` - Platform: Linux x86-64, CPU, single process. - Tiny models constructed...
Trainer reports incorrect final loss and throughput after resuming from a full checkpoint
### System Info - Windows 11 (`Windows-11-10.0.26200-SP0`) - Python 3.14.6 - `transformers` 5.18.0.dev0, commit `f339035b986aaf719bc6f5ea92342f73c498cb0e` - PyTorch 2.14.0+cpu - Accelerate 1.15.0 - Single-process CPU training ### Who can help? @SunMarc ### Information - [ ] The...
