Any ideas on how we can convert a model from huggingface (transformers library )to tensorflow lite?
Author: BENSAFOUAN-Abdelhalim
Pull request: no

### System Info

I want to convert CamembertQuestionAnsewring model to tensoflow lite, i download it from huggingface platform, because when i want to save the model locally it gives me the model with 'bin' format.
i'm asking here because huggingface use pytorch pretrained models.

### Who can help?

_No response_

### Information

- [ ] The official example scripts
- [ ] My own modified scripts

### Tasks

- [ ] An officially supported task in the `examples` folder (such as GLUE/SQuAD, ...)
- [ ] My own task or dataset (give details below)

### Reproduction

when i try to convert the model it gives me this error : AttributeError: 'CamembertForQuestionAnswering' object has no attribute 'call' by using tf_model.h5 file.
Also i can't load it using : tf.keras.models.load_model() it gives me : ValueError: No model config found in the file at <tensorflow.python.platform.gfile.GFile object at 0x7f27cceb1810>.
when i want to save the transformers model locally it gives me the model with 'bin' format, so i download it from the platform.

Maybe of interest to @gante @Rocketknight1 

Hi @BENSAFOUAN-Abdelhalim, `CamembertForQuestionAnswering` is a PyTorch model. The TF model is `TFCamembertForQuestionAnswering`. That's why you're seeing the missing methods on that model!

In general, though, we don't support TFLite conversions for all of our models. There are some operations that TFLite can't support, and we don't guarantee that everything in a model will work for it. However, you can absolutely try to convert it and see what you get!

ok, thanks @Rocketknight1 for your answer.
