`save_pretrained(state_dict=...)` can duplicate tied weights after state-dict materialization### System Info - transformers: main @ c587bc884db2c2e31fc2b8102314656b17aa07b1 - PyTorch: 2.14.0 - Python: 3.14 - Platform: macOS arm64 ### Who can help? @ArthurZucker @Cyrilvallez ### Information - [ ] The official example scripts - [x] My own modified scripts ### Tasks - [ ]...huggingface/transformersUnitedSnakesSep 214 days ago
[P] Wine synthesis using VAE [P].... Is the loss too large? I know that it never could reach perfect zero by how do I know if the loss is good enough? After reaching the plateau? I use MSELoss.. The repo itself: https://github.com/theaidenmax/tabular-vae-wine-generator . This is my second project in VAE (after...r/MachineLearningu/Dangerous-Pilot-6065Sep 1411 days ago
matrix_exp T8 approximation uses an incorrect x7 coefficient...by `compute_T8`. For a small 2D rotation, this causes a reproducible numerical error when a singleton matrix selects the T8 path. A minimal reproducer is: On macOS ARM64 CPU with PyTorch 2.14.0: The analytic reference is the closed-form exponential of which is the 2D rotation...pytorch/pytorchConcode0Sep 102 weeks ago
[BUG] DTensor RNG tracker is applied to CPU tensors under FSDP2 CPUOffloadPolicy, resetting the CPU RNG state## 🐛 Describe the bug When a module is wrapped with `fully_shard(..., offload_policy=CPUOffloadPolicy())`, its parameters keep a CUDA-typed `DeviceMesh` even though the local shards live on CPU. Random ops on those parameters are still dispatched through the process-wide...pytorch/pytorchfrancesco-bertolottiSep 102 weeks ago
[regression] torch.compile(fullgraph=True) fails on dataclasses.replace for a sourceless instance of a sourced class### 🐛 Describe the bug ### Issue `torch.compile(fullgraph=True)` fails to trace `dataclasses.replace(obj, **changes)` when `obj` is a locally-constructed (sourceless) instance of a module-level (sourced) dataclass, as long as `torch._dynamo.config.enable_trace_load_build_class`...pytorch/pytorchkshitij12345Sep 33 weeks ago
