I am maintaining a program that used to do things like  
`TrainingArguments.to_json_string(my_object)` and `TrainingArguments.to_sanitized_dict(my_object)`.

But in the latest version of [transformers/training\_args](https://huggingface.co/transformers/_modules/transformers/training_args.html) (v4.8.2), these two functions do not take arguments anymore. Instead, they act on ‘self’, which is a TrainingArgument object: `to_json_string(self)` and `to_sanitized_dict(self) -> Dict[str, Any]`.

Therefore, I wonder how do I change my implementation accordingly in order to make the same functionality works. Copying functions from transformers/training\_args to my object class solves part of the issue, but works bad when the function has dependencies on other things in transformers/training\_args, and it doesn’t make a lot of sense to copy everything from the transformers/training\_args file to my object class.

What is the best way of doing this? Thank you!

Those functions have not changed since the 14 months ago, so quite a few versions. They have always been methods, which you should call directly on an instance of a `TrainingArguments`.
