Hi @xiaoli, thanks for opening this PR. 

Could you provide some more information about when the error occurs? Does this happen when running with the values from [the example readme](https://github.com/huggingface/transformers/tree/main/examples/pytorch/token-classification#pytorch-version-no-trainer)?<|||||>Hi @amyeroberts, it happened on executing [./run_no_trainer.sh](https://github.com/huggingface/transformers/blob/main/examples/pytorch/token-classification/run_no_trainer.sh), and everything works smoothly but the last step of that saving results into JSON file.

I got this error:
`TypeError: Object of type int64 is not JSON serializable`, so this commit is trying to fix that.

This was happened on my Ubuntu 22.04 workstation.<|||||>```sh
(transformers) ➜  token-classification git:(main) ./run_no_trainer.sh && echo $(date +%d.%m.%y-%H:%M:%S)
The following values were not passed to `accelerate launch` and had defaults used instead:
	`--num_processes` was set to a value of `0`
	`--num_machines` was set to a value of `1`
	`--mixed_precision` was set to a value of `'no'`
	`--dynamo_backend` was set to a value of `'no'`
To avoid this warning pass in values for each of the problematic parameters or run `accelerate config`.

Some weights of the model checkpoint at bert-base-uncased were not used when initializing BertForTokenClassification: ['cls.predictions.transform.LayerNorm.bias', 'cls.seq_relationship.weight', 'cls.seq_relationship.bias', 'cls.predictions.bias', 'cls.predictions.transform.dense.weight', 'cls.predictions.transform.dense.bias', 'cls.predictions.transform.LayerNorm.weight']
- This IS expected if you are initializing BertForTokenClassification 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 BertForTokenClassification from the checkpoint of a model that you expect to be exactly identical (initializing a BertForSequenceClassification model from a BertForSequenceClassification model).
Some weights of BertForTokenClassification were not initialized from the model checkpoint at bert-base-uncased and are newly initialized: ['classifier.weight', 'classifier.bias']
You should probably TRAIN this model on a down-stream task to be able to use it for predictions and inference.

I have reproduced this on my Macbook Air M1 with mps accleration enabled. The full error messages have been posted above here, same as on my Ubuntu workstation.<|||||>@amyeroberts Thanks for your comments!

I think your idea is good, and I understand that your intention is obviously to avoid that `int` convertment of everything. 

But according to this page https://docs.python.org/3/library/json.html
```
If specified, default should be a function that gets called for objects that can’t otherwise be serialized. 
It should return a JSON encodable version of the object or raise a [TypeError](https://docs.python.org/3/library/exceptions.html#TypeError). 
If not specified, [TypeError](https://docs.python.org/3/library/exceptions.html#TypeError) is raised.
```

From my understanding, this `default` parameter is just likely giving a new converter function, and in this case that function is a concise `int()`, yes, that's it. I think we don't need to write a new handler function to handling all different object types here, because we only cannot handle/serialize the `np.int64` here.
So in the future if we have something more than that, I could definitely to write a new hanlder to take good care of them, hence for the time being, I think `default=int` is a good enough solution :)<|||||>Hi @amyeroberts, I have changed that a little bit as you mentioned before :)<|||||>_The documentation is not available anymore as the PR was closed or merged._<|||||>@xiaoli For the quality CI checks, you'll need to run `make style` at the top level of the repo and push any changes that are applied.

@amyeroberts Thanks for intructions, but I am afraid that so many files being changed after `make style` execution:
