This hits CJK stop strings: a CJK character can fragment into tokens that each decode to U+FFFD in isolation,...

ImageClassificationPipeline preprocess should accept numpy/tensor arrays
### Feature request Currently, `ImageClassificationPipeline` expects a PIL image or a string pointing to a URL. This makes using existing datasets (e.g. from `torchvision`) a bit more difficult in the generic case. A non-transformers model would work with torch tensors, but not necessarily with a PIL image, whereas `I...

_load_rng_state after get_batch_samples may break training reproducibility when dataloader has random operations
### Reproduction The current implementation in the `Trainer`'s `_inner_training_loop` for resuming from a checkpoint calls `_load_rng_state` *after* fetching the data batch with `get_batch_samples`. This logic appears to be designed to handle the complexities of `skip_first_batches` and multi-worker dataloading. ...

Several models hardcode `torch.float64` in their forward pass, crashing on MPS (Apple Silicon)
### Summary While auditing recent models for Apple Silicon (MPS) compatibility, I found two models that crash during a normal forward pass on MPS because they hardcode `torch.float64`, which the MPS backend does not support (`TypeError: Cannot convert a MPS Tensor to float64 dtype as the MPS framework doesn't support ...
