how to move DIFFUSERS_CACHE to new version

[LukeLIN-web]

ImportError: cannot import name 'DIFFUSERS_CACHE' from 'diffusers.utils'

The old code is

from diffusers.utils import (
    CONFIG_NAME,
    DEPRECATED_REVISION_ARGS,
    DIFFUSERS_CACHE,
)
class DiffusionPipeline(ConfigMixin, PushToHubMixin):
    @classmethod
    def from_pretrained(cls, pretrained_model_name_or_path: Optional[Union[str, os.PathLike]], **kwargs):
        cache_dir = kwargs.pop("cache_dir", DIFFUSERS_CACHE)
            cached_folder = cls.download(
                pretrained_model_name_or_path,
                cache_dir=cache_dir,

How to modify the old code?

Hi, it's not clear what you want to do, if it's old code it should work with the corresponding diffusers version, the newer versions don't use that constant anymore but you can just use the import for the DiffusionPipeline which is the base class for the pipelines.

If you want to learn how to convert the old code (which I don't really know why) you can just look at the from_pretrained method in the same class here

Thank you for your help. I want to know what is cache_dir use for, whether we can remove it or whether this function is still using?

[asomoza]

cache_dir as the docstring says is:

Path to a directory where a downloaded pretrained model configuration is cached if the standard cache is not used.

you can set it to none if you just want to use the default cache directory the huggingface_hub library uses.

Thank you!
