There are too many causes of AttributeError to pinpoint, but it is said that it can be caused by too old or too new a version of the transformers library.

### Reproduction
Hi,
I'm trying to save quantized model. First attempt didn't work. (I also opened an issue, https://github.com/huggingface/accelerate/issues/1713, to clarify it).
I opened this issue because I'm receiving an error message when I run following code. I'm not sure I'm following the right instructions written on https://huggingface.co/docs/transformers/main_classes/quantization. Because model is pushed to hub in documentation. But I expect to save it to local filesystem. Thanks for your help in advance.
