This category should be used to propose and join existing projects that make use of :jax: Flax/JAX and π€ Transformers. Make sure that your project proposal includes all relevant information (as listed below) for people to join/comment/improve your idea.
Feel free to also post any questions you might have about π€ Transformers [flax examples](https://github.com/huggingface/transformers/tree/master/examples/flax). If you found issues in one of the flax examples, please [submit an issue](https://github.com/huggingface/transformers/issues/new/choose) to the transformers repo instead.
Relevant information when proposing a :jax:/π€ project:
- Description: What is the project about? _E.g._ Train a CLIP model in Swedish for zero-shot image classification.
- Model: What model do you propose to use? _E.g._ [openai/clip-vit-base-patch32 Β· Hugging Face](https://huggingface.co/openai/clip-vit-base-patch32) in Flax/JAX
- Dataset: What dataset do you want to use? _E.g._ [GitHub - google-research-datasets/wit: WIT (Wikipedia-based Image Text) Dataset is a large multimodal multilingual dataset comprising 37M+ image-text sets with 11M+ unique images across 100+ languages.](https://github.com/google-research-datasets/wit)
- Training scripts: What training scripts do you want to use? _E.g._ Training scripts will be created as part of the project
- Expected result: What do you expect the outcome of the project to be? _E.g._ A zero-shot image classification pipeline for CLIP

Hi - I wanted to propose a project. But the submitted projects are really interesting. Is it possible to join more than one ?

Yes, you can join multiple projects!

Just noticed this category, which has quite many topics already. Wow.
A stupid question, I see in README of `JAX/Flax Examples`:
βThis folder contains actively maintained examples of π€ Transformers using the JAX/Flax backend. Porting models and examples to JAX/Flax is an ongoing effort β¦ In particular, these examples are all designed to run fast on Cloud TPUs, and we include step-by-step guides to getting started with Cloud TPU.β
I heard of JAX/Flax before in an nlp coursera class. My understanding is that it is a backend different from tensorflow or pytorch, but why making a big deal out of porting to JAX/Flax? What difference does it bring? I guess the difference and gain must be really big to worth the porting. Thank you very much!
