Justin Chu	73e1455327	[BE] Enable ruff's UP rules and autoformat test/ (#105434) ... Pull Request resolved: https://github.com/pytorch/pytorch/pull/105434 Approved by: https://github.com/albanD	2023-07-19 20:36:06 +00:00
lezcano	d1fedad080	Perform value range analysis with rationals when possible (#105137) ... This is particularly useful for guards to avoid rounding errors, as most guards (all?) are rational functions. Fixes https://github.com/pytorch/pytorch/issues/105097 Pull Request resolved: https://github.com/pytorch/pytorch/pull/105137 Approved by: https://github.com/ezyang	2023-07-13 16:45:47 +00:00
lezcano	19a57870a3	Fix a number of issues with divs in ValueRangeAnalysis (#100547) ... This PR: - Adds `floordiv` and `truncdiv` as they were missing - Maps `div` to its correct definition (it was being mapped to `floordiv`) - Simplifies the bounds of `floordiv` - Fixes some issues with the returned types of `floor` `ceil` - Adds tests for the previous point Pull Request resolved: https://github.com/pytorch/pytorch/pull/100547 Approved by: https://github.com/ezyang	2023-05-04 12:31:55 +00:00
Edward Z. Yang	98ff841a75	Use maxint to bound integers. (#96121) ... We don't actually support arbitrary precision integers. Signed-off-by: Edward Z.

Edward Z. Yang	2f9ffe7b0a	Add torch.utils._sympy.interp (#94985) ... This utility allows us to conveniently abstract interpret Sympy expressions with respect to some alternative domain. I am particularly interested in using ValueRanges to do range analysis on expressions (not this PR). Some minor house-keeping: * ReferenceAnalysis got moved to its own file, sprouted a constant() implementation, and some uses of math.* got converted to sympy.* * ValueRangeAnalysis now understands mod * Test file gets moved from `test_value_ranges.py` to `test_sympy_utils.py` Signed-off-by: Edward Z.
