# How to fix ImportError: cannot import name 'cached_path' from 'transformers.file_utils'

A library you use (txtai, classy-classification, etc.) imports `cached_path` from its old home and your transformers is too new. Upgrade that library; if it has no fixed release, pin `transformers<=4.21.3`. `cached_path` was removed from transformers.file_utils (it lives in huggingface_hub now) in late 2022.

## The exact error

```text
ImportError: cannot import name 'cached_path' from 'transformers.file_utils'
```

## Fix it

1. Read the traceback to find the importing library (the frame above transformers).
   Expected: e.g. txtai, classy_classification

2. Upgrade it: `pip install -U [library]`.
   Expected: the new release imports from the new location

3. If no fixed release exists: `pip install "transformers<=4.21.3"`.
   Expected: import works again

## When this applies

importing a transformers-based library fails on `from transformers.file_utils import cached_path`

## When this does NOT apply

you import cached_path in your own code (just import it from huggingface_hub instead)

## Versions

transformers >= 4.22 with libs importing the old path

## Why it happens

transformers removed file_utils.cached_path; the canonical home is now huggingface_hub.

## Edge cases

Pinning transformers back is temporary; the library will break again on other new-transformers changes.
