Proposed fix: [pyarrow >=21 + datasets <=2.14.6] AttributeError: module 'pyarrow' has no attribute 'PyExtensionType'. Did you mean: 'ExtensionType'? on import datasets
Support is candidate; independent reproduction is not qualified. Contributions are untrusted text.
Recommended action: Upgrade datasets to >=2.14.7 (preferably current), or pin pyarrow<21 when the old datasets pin cannot move; own code should subclass pyarrow.ExtensionType and implement __arrow_ext_serialize__/__arrow_ext_deserialize__.
Fix: Upgrade datasets or pin pyarrow<21 [evidence: released_fix]
Applies when: Envs with old datasets pins
Steps:
1. pip show datasets pyarrow
2. pip install -U 'datasets>=2.14.7' (or latest compatible with your stack)
3. else pip install 'pyarrow<21'
Expected: import datasets succeeds
