ImportError with transformers v5

[albertvillanova]

We get an ImportError when using transformers dev version (current main branch) that will be released as v5:

    import llm_blender
.venv/lib/python3.12/site-packages/llm_blender/__init__.py:1: in <module>
    from llm_blender.blender.blender import Blender
.venv/lib/python3.12/site-packages/llm_blender/blender/blender.py:11: in <module>
    from .blender_utils import (
.venv/lib/python3.12/site-packages/llm_blender/blender/blender_utils.py:22: in <module>
    from transformers.utils.hub import TRANSFORMERS_CACHE
E   ImportError: cannot import name 'TRANSFORMERS_CACHE' from 'transformers.utils.hub'

After investigation, it seems the issue appeared after the merge of this PR in transformers:

• [cleanup] Offline mode and cache dir from huggingface_hub constants + cleanup in PushToHubMixin huggingface/transformers#42391

This PR removed the deprecated TRANSFORMERS_CACHE env variable, but your llm-blender library (one of our extra dependencies) still uses it.

According to the transformers docs, you should use (or fallback to, for backward compatibility) HF_HOME instead.

See our related issue:

• CI fails with dev dependencies: ImportError: cannot import name 'TRANSFORMERS_CACHE' from 'transformers.utils.hub' huggingface/trl#4597

Can anyone take some action on one of the two PRs that are open to fix this simple breakage? Transformers is on 5.8.0 now and TRANSFORMERS_CACHE isn't coming back
