This PR enables ruff pyupgrade (UP) rules with py310 target, auto-fixing
~5600 annotation modernizations (PEP 585 generics, PEP 604 unions,
deprecated typing imports).
Also removes from __future__ import annotations from ir/module.py and
rmsnorm.py, bumps requires-python to >=3.10, and removes absolute_import
aliases from topi/contrib files.
- Set Python minimal version to 3.9 as Python 3.8 has reached end of life
- Update AST handling to match Python 3.9+ API changes
- Fix deprecation warning: "Support for arbitrary keyword arguments is deprecated and will be removed in Python 3.15"
- Update TVMScript parser components to use modern AST interfaces
- Adjust linting and test infrastructure for Python 3.9+ compatibility
[ARITH] Remove deprecated attributes from Constant AST node
Remove the deprecated `s` and `n` attributes from the `Constant` AST node
class in the script parser. These attributes were previously used for
string and numeric constants but are no longer needed in the current
AST implementation.
Updated all code that creates `Constant` objects to remove the
corresponding parameters:
- Removed `s` and `n` parameters from `Constant.__init__`
- Updated `_FIELDS` list to exclude deprecated attributes
- Fixed calls in `evaluator.py` and `parser.py` to remove extra arguments
This change simplifies the AST structure and removes unused legacy code.
* [Script] Be more careful when generating ast.ExtSlice for Subscript
The ast.ExtSlice expects a non-empty list, otherwise evaluation
fails with "error: empty dims on ExtSlice". Also, each element
in "dims" list of ExtSlice must be either Slice or Index.
In python3.8 an expression A[()] is parsed (by ast) as Subscript
with slice being Index(value=Tuple(elts=[])). When we translate a
subscript from doc.AST to ast, we unconditionally convert every
tuple to ast.ExtSlice, which in this case is incorrect.
The fix is to map empty tuple back to the Index(Tuple[])) instead
of ExtSlice. In other cases, ensure that members of ExtSlice are
of correct types.
* Fix lint #1
This PR introduces some minor restructuring of the `python/tvm/script`
folder structure to make it more convenient for future upstreaming.
