According to https://github.com/huggingface/datasets/issues/5230, this is due to Python 3.11 making changes in the dataclasses library:

https://docs.python.org/3/library/dataclasses.html

Changed in version 3.11: Instead of looking for and disallowing objects of type list, dict, or set, unhashable objects are now not allowed as default values. Unhashability is used to approximate mutability.

fields may optionally specify a default value, using normal Python syntax:

@dataclass class C: a: int # 'a' has no default value b: int = 0 # assign a default value for 'b' In this example, both a and b will be included in the added init() method, which will be defined as:

def init(self, a: int, b: int = 0): Changed in version 3.11: If a field name is already included in the slots of a base class, it will not be included in the generated slots to prevent overriding them. Therefore, do not use slots to retrieve the field names of a dataclass. Use fields() instead. To be able to determine inherited slots, base class slots may be any iterable, but not an iterator.

weakref_slot: If true (the default is False), add a slot named “weakref”, which is required to make an instance weakref-able. It is an error to specify weakref_slot=True without also specifying slots=True. TypeError will be raised if a field without a default value follows a field with a default value. This is true whether this occurs in a single class, or as a result of class inheritance.
