Flakiness

test_solution_consistency is explicitly documented in the test file as "intentionally non-deterministic" (it seeds random fresh each run and prints the seed only on failure), so it is expected to be flaky by design; the seed for this particular failure wasn't captured in the CI log.

The failing PR only touches python/tvm/relax/frontend/onnx/onnx_frontend.py and its test file, with no relation to arith, so the failure looks environment/randomness-driven rather than caused by the PR's own changes.

Failure:

AssertionError: Expression x1 * 3 - x0 * 5 - 1 != x0 * 3 + 1 - x1 * 3 
is not true on {x1: I.Range(-20, 21), x0: I.Range(-20, 21)}
Counterexample: x0 = -13, x1 = -17

raised from _check(num_vars=2, num_formulas=1) in tests/python/arith/test_arith_solve_linear_equations.py::test_solution_consistency.
