### Who can help?

@gante and @Rocketknight1

### Information

- [X] 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

Run:
```py
from transformers import AutoTokenizer, TFAutoModelForSequenceClassification

# Load tokenizer and TensorFlow weights from the Hub
tokenizer = AutoTokenizer.from_pretrained("distilbert-base-uncased")
tf_model = TFAutoModelForSequenceClassification.from_pretrained("distilbert-base-uncased")
# Save to disk
tokenizer.save_pretrained("local-tf-checkpoint")
tf_model.save_pretrained("local-tf-checkpoint")
```

Then:
```console
python -m transformers.onnx --model=local-tf-checkpoint onnx/
```

Taken directly from here: https://huggingface.co/docs/transformers/serialization

Looks like some package version issue since I installed it with
```console
pip install transformers[tf,onnx]
```

### Expected behavior

Error
```console

Some layers from the model checkpoint at local-tf-checkpoint were not used when initializing TFDistilBertModel: ['dropout_19', 'pre_classifier', 'classifier']
- This IS expected if you are initializing TFDistilBertModel from the checkpoint of a model trained on another task or with another architecture (e.g. initializing a BertForSequenceClassification model from a BertForPreTraining model).
- This IS NOT expected if you are initializing TFDistilBertModel from the checkpoint of a model that you expect to be exactly identical (initializing a BertForSequenceClassification model from a BertForSequenceClassification model).
All the layers of TFDistilBertModel were initialized from the model checkpoint at local-tf-checkpoint.
If your task is similar to the task the model of the checkpoint was trained on, you can already use TFDistilBertModel for predictions without further training.

Should export models without any error
Uhmmm I am not knowledgeable about ONNX -- maybe @michaelbenayoun has some ideas? 🤔 <|||||>It works on my side. In any case you can try exporting it with optimum:

```python
optimum-cli export onnx --model distilbert-base-uncased onnx/
```<|||||>seems like the issue is with `numpy==1.24.1`. Works with `numpy==1.21.6`. Maybe tf2onnx needs to make some updates. Closing this. Thank you both 😃
