| Let's try out [BetterTransformer](https://pytorch.org/blog/a-better-transformer-for-fast-transformer-encoder-inference/) + [TorchServe](https://pytorch.org/serve/)! | |
| BetterTransformer is a stable feature made available with [PyTorch 1.13](https://pytorch.org/blog/PyTorch-1.13-release/) allowing to use a fastpath execution for encoder attention blocks. Depending on your hardware, batch size, sequence length, padding ratio, it can bring large speedups at inference **at no cost in prediction quality**. As a one-liner, you can convert your 🤗 Transformers models to use BetterTransformer thanks to the integration in the [🤗 Optimum](https://github.com/huggingface/optimum) library: | |
| ``` | |
| from optimum.bettertransformer import BetterTransformer | |
| better_model = BetterTransformer.transform(model) | |
| ``` | |
| This Space is a demo of an **end-to-end** deployement of PyTorch eager-mode models, both with and without BetterTransformer. The goal is to see what are the benefits server-side and client-side of using BetterTransformer. The model used is [`distilbert-base-uncased-finetuned-sst-2-english`](https://huggingface.co/distilbert-base-uncased-finetuned-sst-2-english), and TorchServe is parametrized to use a maximum batch size of 8. **Beware:** you may be queued in case several persons use the Space at the same time. | |
| For more details on the TorchServe implementation and to reproduce, see [this reference code](https://github.com/fxmarty/bettertransformer_demo). For more details on BetterTransformer, check out the [blog post on PyTorch's Medium](https://medium.com/pytorch/bettertransformer-out-of-the-box-performance-for-huggingface-transformers-3fbe27d50ab2), and [the Optimum documentation](https://huggingface.co/docs/optimum/bettertransformer/overview)!""" | |
